Title: Greetings and Questions about K75
Post by: VAK75 on September 02, 2019, 01:56:16 PM
Hello all!

New member from Virginia, USA and prospective K75 purchaser/owner with a number of questions.  Hopefully I'm in the right place to ask them?

I'm in the early stages of researching the purchase of a K75.  I'm focussing on the K75 "standard" (is that the right terminology?) for the low seat height.  I also prefer the simple clean look of this version.  I'd like to find a late-model ('94/'95) with low miles and ABS. 

My first questions concern the optional ABS.  Can this option still be added to a K75 that was not equipped with ABS from the factory?  If yes, is it an oem solution from BMW, or aftermarket?  If no, what is the general sentiment about the desirability of the ABS feature on a K75?  (I come across many good candidates, but they often lack ABS.)

My second question concerns oem or aftermarket saddlebags and associated mounting brackets/legs/hardware.  Are these readily available new?  If not, how difficult is it to find them on the used market?

I have more questions but will hold off - - don't want to overload you folks and not even sure if I've posted in the correct location. 

Thanks!

greetings...

to add abs to nonabs brick it will likely have to be oe... you will have to source all the components... will costs thousands for sure...

oe is the way to go for side bags and top box... they are available new and used... click on parts guidance and getts familure with the fische... butts you can fit anything on there f you have tools and skills and piggy bank...

you can find a seven fitty with everything you want if you are patient and wait for the right one to go up for sale...

j o

Thank you.  This info is very helpful.

Agree with Johnny. I would never attempt to add ABS to a non-ABS bike.  There are too many hoses, pipes, pumps, rotors, wiring and a computer to add that would make it not worth the cost or effort while there are fine bricks on the market if you are patient.

Here is an example I found nearby Craig's List -> https://easternshore.craigslist.org/mcy/d/ocean-city-1987-bmw-k75c/6960335395.html

While it does not have ABS it looks clean, has low mileage with cases and it appears the seller is knowledgeable of spline maintenance.

Thanks for the welcome.

My riding experience is very limited.  I took the MSF Basic course a few months ago.  Shortly after that, I purchased a small starter bike (2016 Honda Rebel 250) on which to practice and build my skills/confidence.  I have only logged about 500 miles on it so far. 

But I live in a congested urban environment, so 100% of that is in pretty challenging riding conditions with tons of stop/go and traffic (I have seen references on this website to the detours riders take to avoid my
area.)  It usually takes 60-90 minutes to travel about 20 miles around here.  So my time in the saddle is more than the miles suggest.  But I have very limited time at highway speeds.

I recognize my inexperience, and plan to keep riding the Rebel for quite a while yet.  I may even keep it as a second bike when I eventually upgrade - - it’s actually a lot of fun to ride and well-suited to this area.  But these K75s interest me and due to their age will need a thorough going-over before using.  So I am beginning to sniff around.

Most bikes I see of the vintage you are interested in have both side cases and ABS.  Top cases are fairly easy to find if you aren't in too much of a hurry. 

ABS is an OEM system.  There is too much stuff to put together to make the system work.  Personally, I have it on my bikes because they came with it.  It's nice because it gets an insurance discount of $10-20 per year.   I have actually activated the system only once to see if it was working.  Normally, I am leery of hitting the brakes hard enough to activate it because I don't want to find out it isn't working.  Alert defensive driving is more valuable to me than ABS.

Luggage is readily available on eBay along with the necessary hardware.  Adding it is strictly an easy bolt on task as long as the bike has the rack mounted on the tail cowl.  No big deal if the rack isn't there.  You just need to spend an afternoon removing the cowl and drilling four holes.

Copy, thanks.

So adding ABS is a no-go.   What is the consensus on the desirability of the ABS feature?  I know ABS is a good thing in theory,  but how is it holding up on 25-year-old bikes?  Reliable, or problematic?

Welcome!

I've seen this listing for some time in the NYC area. Clean looking moto, very low miles, looks like "C" type bars not Sport bars
I don't know if its Mystic Red or Marrech Red but I doubt you find another like it

https://newyork.craigslist.org/lgi/mcy/d/hampton-bays-1994-bmw-75/6965416034.html

Another Low Seat model recently listed

https://newyork.craigslist.org/mnh/mcy/d/new-york-1995-bmw-k75/6967337429.html

I saw another NYC K75s for sale from one of the MOE's here. Don't know if it was sold or not

Good luck with your search

As with any brand-new technology, the 1st iteration is often imperfect.

So it was back in the 1980s with the BMW K-bikes, the very first motorcycles with ABS.

Their ABS was good... for the time.  In no  way was it a perfect system.  It was a 1st try at it.

Welcome to the forum - I have a K75 and am in central Arlington, likely right next door to you, figuratively.

My K75 started life as a "low seat" model.  It is now a "regular/aftermarket seat" model, by my choice.  It took me across the country this Summer.  Frankly, unless you are a VERY short person, I would advise a regular model because the Low Seat model has some significant storage and tool limits.

Go ahead and PM me if you want "life with a K75" -type advice, etc.

Your Rebel is more suitable for chronic traffic congestion; furthermore, you'll develop much needed low-speed skill riding that moto in traffic. Low-speed maneuvering is an essential skill easier to learn and perfect on a moto lighter than a Brick. I recommend viewing Jerry Paladino's Ride Like A Pro Series. Once you've picked up that skill, it will make riding a larger moto more pleasurable.

The Brick wants to be run on the open road as frequently as possible. In congestion its fan will bathe the rider with heat periodically although the naked Brick will be cooler than one with a fairing.

An electric moto would seem to be ideal for congested traffic. More are becoming available on the used market.

Thanks for the ABS insight. 

Yes, we are near neighbors.  Don’t be surprised to get a pm from me - - I would be curious to test that seat height.  I am only 5’ 7”, with a disproportionately short inseam (28”).  I was assembled from the spare parts bin.  The low seat height of “Standard” trim appeals to me - - I want to be able to flat foot.  As I understand it, the K75 standard had an oem low seat as standard equipment.  (Does anyone happen to know the seat height measurement?)

Incidentally, in your signature you list your 1995 K75 as a “T” model.  I thought the T was only made from ‘86-‘87?

According to Phil Hawksley's site, 29.90 inches is the low seat height.

As far as the T designation goes, don't get tangled in minutiae.

Thanks for the tips.  Like said, I expect to be on the Rebel for a good while.  And if possible will hold onto it after acquiring my “next bike.”  It is a great platform for practicing skills, and for riding around here.

I am considering the K75 for other purposes.  The Rebel is a great bike, but highway cruising is not it’s strong suit.  I would be using the K75 for longer road trips, cruising with camping gear, etc.

How much does a K75 Standard weigh?
Title: Re: Greetings and Questions about K75
Post by: Laitch on September 02, 2019, 06:38:53 PM
How much does a K75 Standard weigh?
Slightly over 500lbs with all fluids and ready to ride. The Rebel weighs approximately 330lbs. The Rebel has approximately 16 horsepower; the K75 has around 65 horsepower. Experience, good judgment, coordination, upper body strength and humility would be helpful to have before you climb on one.

You are welcome to sit-test... I have a very nice used Corbin seat and I junked the OEM low seat.

My bike was ordered by the original owner (as relayed to me by the 2d owner) with the "Touring" plexiglass windshield.  It is a late model (1995)K75 with the standard, or "C" handlebars, a huge round headlight, OEM "City" baggage cases and the OEM 22-liter top case, and this windshield.  I therefore call it a "T" because it is decently set up for touring.

Hope this helps.

BTW - in my experience on several bikes, "flat-footing" while at rest, although reassuring, is not really necessary as long as the rider's toes can touch the pavement on both sides.  By contrast, bikes designed to sit the rider low can be quite hard on our tail bones at the bottom of the spine, because the lower the bike, the more weight that body area has to support.  Also, on "low" bikes the seat material is often skimpy, adding to the problem.  Both these factors often manifest on longer rides.

Thanks.  Yeah, I have spoken with the owner.  It seems like a really nicely fixed-up K75.  Unfortunately he did a seat conversion to raise it up several inches.

I have a gimpy ankle/foot and flat-footing works best for me.

Low seat and associated mounting hardware can be found and most of the mounting parts are still available at MAX BMW (https://shop.maxbmw.com/fiche/DiagramsMain.aspx?vid=51741&rnd=07242017)

This MOE was looking to trade his low seat for regular seat

keep watching the local clist and be patient.  i got both of my K75's through the DC clist.

although the ABS on these bikes is first generation and  very primitive, it works.   if the bike is maintained well the system is very reliable.  make sure it is working on any bike you look at.  easy to tell, there should be no lights flashing in the cluster after rolling the bike a short ways and hitting both brakes.  i intentionally excercise mine regularly.

+1 for the Seller. Great guy. Bought my K1100RS from him. I believe he has a couple ads up. He was downsizing his fleet when I was visiting/purchasing.

As far as testing the ABS, when you say “after rolling the bike a short distance”,  is that with the engine on or off, in gear, etc?  Just trying to better understand the test procedure.  Thanks.

I’m surprised at that measurement for the low seat height. I can get an F 750GS with a similar height seat, and that’s an adventure bike with quite a bit of ground clearance.   Also, Hawksley’s site shows the same low seat height for all models across all years.  Is that correct?

Not getting tangled in minutiae, just curious about his K75 model.  It seems some others are as well.


Slightly over 500lbs with all fluids and ready to ride. The Rebel weighs approximately 330lbs. The Rebel has approximately 16 horsepower; the K75 has around 65 horsepower. Experience, good judgment, coordination, upper body strength and humility would be helpful to have before you climb on one.

Good luck on your search for a brick.
I'm also short on the inseam, and found the K75 top-heavy and cumbersome if wearing the flat sole AlpineStars, whereas, wearing the lugged sole work boots is 3/4" of instant confidence at stops. The handlebar is also critical to parking lot slow speeds, and feels much better at a higher setting (K75S) ... even though I prefer being bent over with "strap-ons" ;)
FWIW, I'm across the river from you, Waldorf.

To solve height problems. As per Nat thicker soled motorcycle boots are available gain 1" +. Shoe lifts gain 1" +. Drop the forks through the trees 10-12 mm. Shave the nose of your OEM seat. Have your seat lowered by a competent upholsterer. Fit the optional 1" lower rear shock, however  your cornering clearance will be reduced. And you will have to shorten your centre stand unless you are super strong.

Your bike is a K75 Sport, correct?  Was that offered with a low-seat option and does yours have it?

As I understand it, on the K75 Standard the original equipment seat is a low seat, not an optional seat choice.   Have you ever compared the height of your Sport bike’s seat to the low seat on a Standard?

Yes, it's an "S" with the standard "S" weird, welded bar. I have a comfort seat on mine, it's a great for longer days, and my wife says the pillion is spacious and comfy.

I've test ridden a low seat K, just a short distance. This was a potential buyers ride for 10-15 mins around the neighborhood. It was noticeably easier to flat foot, although I ended up getting the brick with the comfort seat and just slide a cheek to the seat edge if needed in wind or an off-camber road. Once moving there's little to notice in seating, except the low seat option is easier to shift around on.

As far as seat comparison's, it's really odd, but I felt super confident on an XT600 with aftermarket springs and 34" seat height, and never felt secure and solid on a CB750F which is about 31". Riding with dirt riding gear and boots probably had a lot to do with it.

Low comfort seats were also manufactured, come up for sale every once in a while and would fit S models, too.

While I've ridden a lot of motorcycles over the past 15 years most of my miles have been on a Vespa GTS 250 scooter.  Similar weight to the Rebel.  Six weeks ago I got a 1992 K75 and at Laitch indicates -- the increase in weight demands a few considerations.  That said, I've found the K75 an easy machine to deal with compared with others I've ridden.  Perhaps the biggest challenge for me is learning to be a bit more respectful of the weight when getting on and off the motorcycle.  The scooter is so light that I can throw it around, push it, pull it and get it on the center stand from a lot of awkward positions.  Not so with the K75.  I've had to develop some good habits with both the slow speed maneuvering and the no speed handling.  But otherwise, if you are completely comfortable with the Rebel you'll make the transition ok.

One other thing -- I'm 6'2" so I can easily flatfoot the motorcycle.  That definitely helps.  On the negative side -- at 65 years old I'm not as strong as I once was so I have to be a bit more careful with handling.

Anyway, hope things work out for you.  The K75 is a joy to ride.

I have a 94 ABS standard model. Bike is a very easy machine compared to my R bike. It is rather heavy though, but this feeling goes away once you get rolling. The handling, ride and cornering are excellent. It especially likes around 5500rpm on highway in 5th. I ride my K75 every day. Good luck in your quest for a nice one. Its a great machine.

Thanks for the info and encouragement.

I like the idea of the ABS, but am now softening somewhat on that requirement based on the info gleaned here.  I still would definitely prefer one with ABS, but may consider one without ABS if it is an otherwise outstanding candidate.

What sort of speed are you seeing at 5500 rpm in 5th on the highway?  Does a K75 have 5 or 6 gears?

What is it about your K75 that makes it an easy machine compared to your “R bike”?  R bike being???

Thanks.

The problem many have is not with the moto's rolling weight; it's with its static weight. Once it is tipped, it is difficult to keep it from falling unless the rider is strong and has firm footing. Once fallen, it takes personal strength or the combined effort of two people to raise it.

The solution, of course, is to stay aware and keep the moto balanced.

While I've ridden a lot of motorcycles over the past 15 years most of my miles have been on a Vespa GTS 250 scooter.  Similar weight to the Rebel.  Six weeks ago I got a 1992 K75 and at Laitch indicates -- the increase in weight demands a few considerations.  That said, I've found the K75 an easy machine to deal with compared with others I've ridden.  Perhaps the biggest challenge for me is learning to be a bit more respectful of the weight when getting on and off the motorcycle.  The scooter is so light that I can throw it around, push it, pull it and get it on the center stand from a lot of awkward positions.  Not so with the K75.  I've had to develop some good habits with both the slow speed maneuvering and the no speed handling.  But otherwise, if you are completely comfortable with the Rebel you'll make the transition ok.

One other thing -- I'm 6'2" so I can easily flatfoot the motorcycle.  That definitely helps.  On the negative side -- at 65 years old I'm not as strong as I once was so I have to be a bit more careful with handling.

Anyway, hope things work out for you.  The K75 is a joy to ride.

Thanks for that feed back and encouragement.  Good to hear you transitioned relatively easily from the Vespa.  We have a couple Honda scooters as well, so although the Rebel is not nearly as heavy as the K75, I do have a good idea what you’re talking about. 

It took a bit to get used to the extra heft of the Rebel, but now I’m pretty comfortable with it.  I’d like to think these skills will transfer well to any larger motorcycle.  Unless there is something especially cumbersome or poorly designed with the weight and balance of a K75?

I don't think you'll find any difficulties adjusting to the K75 unless you can't flat foot the bike.  Then it might seem cumbersome, especially moving it around.  Just go slow and practice a bit.  Whenever I take a new motorcycle out I usually spent 15 minutes or so in a parking lot experimenting with brakes, clutch and slow speed maneuvers.  Everything feels more cumbersome than the Vespa but you adjust rapidly.  The only motorcycle I remember not adjusting to was the BMW K1600 GTL.  It was a whale.  Nice on the road under power but don't ever stop or try and do a U turn.  Geez it was big and heavy.  I've never ridden a Goldwing but I sense they are similar.

There is something that can be especially cumbersome about the classic K models. There is plenty written on this site about the need for awareness of its balance point when maneuvering it slowly. Your riding skills will transfer from the Rebel to the Brick once they are thoroughly embedded in your awareness; however, cruiser-style motos like the Rebel differ from Bricks. They place the rider closer to the pavement thus giving the rider's legs stabilizing advantages.

You'll want the benefits that a low-seat on a K75 might give you. You'll need the benefits that riding thousands of miles on the Rebel first will give you.

What model and which seat height did that bike have?

He went straight from scooter to K75?  Did he take any training courses or learn to ride on a smaller bike first?  (Scooters don’t count.)

If you're referring to me -- I ADDED the K75 to the garage.  So now I have a K75 and a Vespa.  I've taken the Beginning Rider course once and the Advanced Rider course twice.  It was about 15 years ago when I "returned" to riding.  Hadn't gotten on a motorcycle or scooter since high school in 1971.  So the courses were useful and I recommend everyone take them.  Learning to ride is the easy part.  Learning to be on the road is the hard part.  It's like you have to get past all the things you believe riding in a cage.

After a few years with the scooter and having started a blog that suddenly started getting a lot of traffic, the local BMW-Vespa-Ducati-Triump-URAL dealer asked me if I would be interested in doing reviews.  He would give me whatever I wanted and I could play with it and write something on my blog with a link to his place.  So for several years I always had a motorcycle in the garage along with the scooter.  I estimate I put 10 to 15 thousand miles on various machines.  So I wasn't unfamiliar with something as big as the K75 but it had been a few years since I rode anything other than my Vespa.

My K75 has the low seat.  It's fine even though I'm 6'2".

I've seen plenty of men buy a big bike early and regret it because they never got past their uneasiness.  As someone already said, put a lot of miles on that Rebel before you step out for something like the K75.  You'll thank yourself later.  And you'll also learn consumption patience -- a wonderful opportunity for personal growth.

If you need additional restraint and you're married, tell your wife that unlike the slow and underpowered Rebel, the K75 will go 130mph!  She'll probably help you wait.

as i said in my post..it was a K75S

it had a corbin seat, which is slightly lower than the standard K75S seat.

Sorry, I misread your post as “K75’s”, not K75S’s”. 

I was genuinely interested to hear more details about his path from scooter to K75.  If he went straight from the scooter to throwing a leg over the K75, without any additional training or practice on a smaller bike, then it’s not surprising he ran into trouble.  But if he took training and practiced extensively on a smaller bike first, then that could certainly say something about the unforgiving nature of the K75.

Your statement that his friends goaded him into buying a motorcycle, if accurate, suggests he might have hurried the process.  Also, if he was short, he should have targeted a Standard with the low seat.

I met up with Brickdad today who very kindly offered me the opportunity to examine and sit on his K75.  His is a very nicely maintained and equipped Standard, and he added a Corbin seat to replace the standard low seat.  (His city cases are VERY nice - - much less bulky than the larger cases I’ve seen in photos.)

The K75 feels big and heavy compared to the Rebel (no surprise.)  The seat height was too tall for my leg length. 

Brickdad estimates that his original low seat would reduce seat height only by about an inch.  I will have to test a low seat.  If it only gets me an inch closer to the ground, I’m not sure if that will be enough.

Is a suspension lowering kit available or was a low suspension ever offered as an option on the K75?

As per my previous post 1/ Thicker soled motorcycle boots will give you an 1" plus. 2/ Shoe lifts another 1" plus.3/ You can drop the forks through the trees 1/2' with no adverse effects. 4/ Have the seat nose shaved this will allow you to better get your legs down and give you another 1"plus or minus. 5/ Have the seat foam redone by a competent upholsterer to lower the whole seat. 1" plus. 6/ Get a 1'' lower rear shock but this will effect the handling and your ability to get it onto the centre stand. This can be overcome by shortening your stand legs. I am 5'7" with short penguin legs. I have lowered my front forks through the trees 1/2" wear thicker soled boots, shaved and lowered my seat and I can flat foot with bent knees.

The bike I bought last week has a low after-market seat.  I have a 32 inch inseam and can plant the ball of my foot on the ground when the bike is on the center stand.  I'm just coming back to riding after a long break and I like the low seat for the time being.  I've been practicing low speed maneuvers and it's reassuring to know I can put my feet firmly on the ground if needed.

I've only been out riding the k75 3 times since I got it this week.  The bike is very easy to ride.  I can make tighter circles on this than I could on the TU250 I used for my BRC course 2 years ago.

As far as finding your bike.  I looked for on craigslist for 2 years before I found the one for me.  After looking for awhile I stopped worrying about finding one that had low miles.  I decided that I would rather have a k75 with 50K that has been lovingly maintained and actually ridden, than one that has 12k and sat in a garage for the last 10 years.

While searching, I called local BMW mechanics and asked them what are the main things to look at.  All of them were happy to spend 10 or 15 minutes educating me.  This also helped me decide where I was going to go for maintenance.  The BMW dealership only had one guy that worked on old bikes and his schedule was booked months ahead.  I found a small place where the owners had worked on old BMW's for years and had a great reputation.

Thank you, johnny, Martin, volador, and wiarmu for the suggestions.  This info is very helpful.  Martin, sorry I misssed your earlier post with all the tips for gaining some inches - - it’s all very encouraging.

Brickdad’s K75 really impressed me.  There’s a lot of engineering and clever features in these bikes. Plus they look awesome.  I am not ruling out a K75 yet and hopefully I can make it work.  Planning to watch local craigslist and see if anything materializes locally.  But it could be a while before I end up buying one - -  I have a good training bike so I’m not in a hurry.

Thanks for the suggestion.

I’ve sat on the CTX at Honda dealers.  They are an interesting bike, with a nice low seat.  Very sleek and modern/hi-tech.  Most of the new ones come with automatic transmissions.  They kind of remind me of a 3/4- or 4/5-scale Goldwing.

But here’s the thing, I prefer older classic styling over sleek/modern.  I guess I’m more of an analogue guy.   Though they are different styles of bikes, my Rebel 250 and the K75 are more in line in that respect.

Another member here suggested I should explore the BMW R65.  I know this forum is dedicated to K bikes, but from what I see in signatures there are quite a few airheads here as well.   Does anybody have any first hand feedback on this model?

Yeah, I have seen the ad for that one.  Looks very nice, relatively close by, original owner too.  But it’s a 1980 model, and from what I’ve learned so far it’s preferable to find a later model year with point-less ignition.  And some other tweeks came along that improved the R65 later in the production run. 

Also, they seem to be pricey compared to K bikes, and objectively the K bike appears to be a much more advanced machine... But I’m still in the information gathering stages.

Have you ever had your K75 side-by-side with the R65LS?  If so, can you give me your impressions of the size difference, particularly with respect to seat height?

Oddly, the published specs suggest that an R65 is actually a taller bike than the K75.  I find that hard to believe but have never seen one in person.  From what I understand, the R65 was built on a smaller frame than the R80 etc. 

That said, the published spec also shows the R65 to be a lighter bike by about 50 lbs (10%).  It could well be that that it has a much lower CG as well, with the boxer engine.  But the brick engine doesn't exactly look like a high CG arrangement by any means.

I graduated from an LS to a K75s back in '86, kept the LS for a couple years then sold it because I never rode it anymore.  Impressions: relatively slow, buzzy enough to put hands to sleep, It seemed much more than 50lb lighter and made the K feel really top heavy.  Hard luggage was hard to find, smaller frame didn't accept R80-100 gear.  I never recall the seat height being an issue with my 30" inseam, could be the narrower seat made it easier to flat foot than the K.  It was a fun around town bike but not much fun for all day superslap jaunts.  Here's a side by side pic.

Can’t thank you enough for that feedback and photo.  Man, that was a super-sweet combo of bikes you had there for a while! 

They look to be pretty close to the same size.  Do you suppose the sense you had that the R65LS was more than 50 lbs lighter came from a lower CG?   With your 30” inseam, how does the height compare on the K75S and does it have the low seat or standard?

What a dilemma!  Your input hasn’t made my decision any easier.  These are both nice options - - from what I’ve learned the R65LS has many of the neat features that are on the K bikes (I’m primarily thinking of the  underseat storage.)  It’s almost like the “missing link” between the old airheads and the “new” K bikes.

They really aren't. The LS is just closer to the camera, the jump to the K is significant in weight, & power.  Never had a low seat so I can't really comment on them but never had much trouble with the height of the k75.  I have the 3/4" shorter shock and lowered the forked tubes 1/2" in the triple clamps.  Can't quite flat foot it but it's no big deal.  The LS back then was refinement of a many decades old design, the K was ahead of it's time.  The difference was like jumping from a bugeye sprite to a 911.  Never missed or regretted selling the LS, nor have I felt the need for something more modern than my K.  But that's strictly a personal opinion.

Interesting site that may help or may totally confuse you.https://www.bikesales.com.au/editorial/details/cycle-ergo-bike-size-test-22558/ And at 5'7" with the legs of a penguin if I can sit on a 75 with bent knees so should you.

. . . with the legs of a penguin . . .
Let's not bring birds and beasts into the discussion, Martin. It's already unsettling enough for some people.

Sorry Laitch I'll try to refrain from animal comparisons. However at the time of the operation that was all that was available. As a result I'm a much better swimmer now.

 Hi, I've got a 30" inseam and can easily flat foot the low seat (1993) k75, so i think it will fit you okay even with less inseam to work with.  Seat height in itself isn't the end all on comfortably reaching the ground, also to be considered is how fat the seat is at the front.  When it's wide, it will push your legs out more making in effect a longer reach to the ground. 
 On ABS, i wouldn't be stuck on that, rather find a nice, low mile, well maintained example and if it has ABS great, but if not you won't miss it probably.  Personally I search out models without ABS for less complexity and the extra plumbing that comes with the system.  Good brakes, and proper application of the brakes is key to survival in my opinion.  Unless you plan on riding a lot in rain, or in icy conditions, probably isn't necessary.  Good luck with your searching.  scott
Edited to add pic, this is a stock low seat, really low, Just like my r100r Mystic, same height i think.

I only just now learned that Motobrick is a “virtual gay bmw biker bar.”  My fault for not checking the aggregating sites before signing up.  No judgement - - just not my thing. 

Thanks to those who provided helpful info.  Safe riding to all.

It is?  I was unaware of aggravating sites but maybe I need to  check them.

Anyway, at 5;10", and 32" inseam, K75 which in my case is normal seat is easy to get both feet flat on the  ground. It's hardest to move around at a stop. Mine has gotten tired and laid down a couple times, always at a dead stop or nearly so. A few times as I was trying to get onto center stand.

Engine protection bars and tragkorbs help a lot, you don't have to lift it so far.

PS if you do get one, don't forget to lube the splines. I found lack of spline lubrication to be a real pain in the ass.

At 5'7" and 29" inseam my low seat conversion this past summer was next to installing radials the best mod I've done.  And yes Mystic Red is faster. 

My first brick was non ABS my current is Gen 1 ABS.  I can push the brakes farther, deeper with the ABS ready to "click click click" when adhesion ends.  I like. 

My current project is Gen 2 ABS.  My 94 with 70k I paid a premium, 3k, knowing  I could click up 10k miles without a thought of doing major service except spline lube.  In October a reasonable garage queen on Craigslist is a $1500 idea.

My current K1100 was a $500 Craigslist find. Fill piggy banks, be patient.
