Title: How Fast is Fast?
Post by: argent brick on March 29, 2013, 07:54:45 PM
I just have a couple of fun & silly questions for all of you Brickheads. What is the top speed that you have ever done on your brick? That is the main question. The secondary question is this: What bike modifications did you have to make to achieve that speed?

125 MPH on the interstate. She was stock back then but now I am running with better injectors and tires!

I hit an indicated 110 couple of times,  removed airbox and fitted a conical K&N filter to the air meter, with a Supertrapp or Goofmaster pipe, but those mods were more to look and sound cool than add any real performance.  It is a 2v K, yaknow.

LOL The first time I raced anyone was on Hwy 99,  Sacramento to Stockton.  I was on a R60 and the other guy was on a Honda 750. I lost big time but it was worth it because he got really pissed that a Tonka toy R60 could even come close to his 750. Within a week, he went through his whole bike. Top to bottom.

116 per GPS while the speedo read about 130. No mods and would have kept climbing.

First try, the Givi fairing wasn't up to it.

Second try, rev limiter in 5th on a nameless reservation road.

According to specs, that should be 134 mph.

Although there's not so much air to push aside up here on the high desert, I'd wager that the real speed was   somewhat less than what the book claims.

All is stock. Wouldn't mind a 4 valve motor.

Stock on a K1200 with a Givi E52 trunk and saddle bags.   :2thumbup:

(of course I won't tell you it is a glitch and it appears that it is reading in KPH since on the run that day I hit maybe 125 to 130 mph tops on a straight ... I have really topped 140+ according to the Nevada Sate Troopers tho)

I had the old girl up to a GPS indicated 98 once (105 on the speedo). It had more, but in western WI it can be tough to find a straight road without cops. (Summer project?)

I went 80 the other day. That'll probably be enough for me. Must've gotten all that propensity for risk taking behavior out of my system in my younger days. Plus, my teenage son is getting ready to go on my auto insurance. I don't need any infractions of the traffic laws driving up the cost even more than it will already once he's on there.
Title: Re: How Fast is Fast?
Post by: motodude on April 03, 2013, 12:12:39 PM
Indicated 110 mph; at Portland International Raceway; Bone stock '90 K75RT w/ 96K miles on it and about 30 psi in the tyres.

Of course, I would never go anywhere near that on a public highway.   :nono

Yeah I hear ya, I'm not afraid of going fast but I'm sure afraid of facing my wife when I have to explain a speeding ticket!

Ran my 86 K100 in New Mexico up to 145mph, wanted to keep accelerating but bike started to wobble as I got to about 135.
Title: Re: How Fast is Fast?
Post by: Grim on April 14, 2013, 10:13:58 PM
60mph but I'm on a learners so not allowed on the hwy yet. LOL

Now the fastest I have ever been was in my company work van. Those LS 5.3 motors are the BOMB!  I managed to get that thing going fast enough I drove across the gulf of Mexico!

 GPS confirmed.

(dont tell my boss he doesn't like when I go over the speed limit)

120 indicated between Atlanta & Montgomery last week, 86 k100 RS w/bags & fairing.  Felt good @ 115mph.  120 got a little scary so I backed it back down to the speed limit..

120 indicated on a fairly regular basis, '92 nekid K75. According to Duck, that prolly means something less than 110 due to the 10% discrepancy with the stock speedo. Need to load a proper GPS app into my iPhone to confirm.

Me too, here in Finland. But I'm quite sure the speed meter of my K75 is very optimistic and that's why I may sometimes ride with high numbers on the speed meter...  :hehehe

(Not K-series bike but I was testing a Honda Blackbird: 1st gear max was 160 km/h = 100 mph, then to the max of the second and third gear and I suddenly felt the curves had strangely changed to very tight ones and I never saw the 300+ km/h = 190+ mph digits the owner says it goes... So it must have even more optimistic speed meter because I would never exceed the speedlimits...  :D )

Actually I usually follow speed limits very well because if speeding, my back starts to hurt. It's somehow related my wife sitting on the backseat...  :hehehe

Riding my new K75S home from SF on the 5, she started vibrating and the wind was acting like it does on my GL500 at about 75mph.

I glanced down to see I was doing 105mph...  :eek:

I'd never even hit the ton on the Honda, so I tucked in, got up to 112 and then backed off to regular freeway speeds for the rest of the trip.  :curvy-road

Oh, back when there was no daylight speed limits in MT, I met the MT state police coming the other way when running an indicated 95 mph on US 212 heading toward Little Big Horn.  I didn't roll off and he didn't bat an eyelash. 

Ya gotta love that those K-bikes will run at those speeds for hours on end without any drama.

I remember wondering what the cops would think was, "reasonable and prudent".  That's why I kept it in double digits.  I figured triple digits they might consider to be a bit beyond that particular metric.

:riding: Is there life beyond 65???

I had a friend that used to ride a SECA 650 and he wore a t-shirt I loved, I've looked for one but to no avail. I played around and came up with something similar, I think I'll have some made, what do you think...

When I raced I had a shirt that said Life Begins at 170 and a GP 500 bike on it - I don't know that it begins there, but it sure makes you assess things differently.  :hehehe

Around 150 kph, I think, which would be about 93 mph. That was testing the bike out when I first got it.

Been up to 140 kph while passing folks on the highway more than enough times since then, but that's about it. More than fast enough for my terrible eyeballs. Course the speedo on mine seems to be about 5 kph high (which is quite a bit!), but I'm taking that into account.

Not too fast by your guys standards…. Last weekend I did a mountain road trip with a passenger on my 90 K75RT and was hitting 80mph in the twisties, had it cranked over far enough that I ground down the outside of my shoes a bit. That was a great fun ride. I'm not too inclined to do top speed runs in this part of the world because of the wildlife risk, I've only had the bike a couple months and already clobbered a deer that spooked out of a ditch in front of me. I got super lucky and managed to stay on the bike and keep it upright, took the deer in the shoulder/chest area and had a good splat mark on my coat from the deer fur after.

I think I clipped 100 today. Group I was riding with didn't all make a a turn. The Sweep (my cousin) and I got caught by traffic. Heard him tell the lead we would catch up so I did. Looked in my mirror and Cuz was playing catch up with me on his brand new Harley lol
I was really impressed how solid it felt and howchard it was pulling. I really didn't realize I had wound it out that much. Then scrubbing off the 40 or so surplus MPH so I could drop back in behind the group was a little scary.

If I can figure out my 12year old GPS it may have the actual speed in it. 
Title: Re: How Fast is Fast?
Post by: Oma Aika on August 27, 2013, 12:57:14 AM
Yes, my K75 too is very solid and nice to ride 100-110 mph even with passenger.
Title: How Fast is Fast?
Post by: TaosBrick on October 01, 2013, 11:39:44 PM
Achieved a personal best of an indicated 130mph on my Chile Red K75 today. Guessing that to be something over an actual 115. Figger that must be all there is, as I held it wrung out all the way for over a minute.
  Solid as a rock, smooth as glass - Wheeeeee!!

116 mph on a K 75,downhill with a tailwind.

Unless your top speed is verified by GPS or a LEO it's probably inaccurate on a BMW speedometer. Well known to be 10% or higher.

Is it really? Maybe it can be adjusted or depends on tires? My ex-police bike's speedometer shows exactly (+/- 1 km/h) the same numbers as my GPS.

Post by: TaosBrick on October 02, 2013, 09:30:42 AM
Yeah, Th' Duck sez they categorically run 10% over. I believe he also posted how to fix it in The Lieberry. But this involves dickin' with teeny weeny electrical parts, soldering and other forms of Black Majic Hoo-Doo where I fear to tread.

Strange... either something has been done to my brick or there are different speedometers  - different for mph and km/h versions? For European/American versions? I've never tested any other bricks so I can't say much. Mine is very accurate though.

Police bikes have a specially calibrated speedo. Needs to be done if they are giving tickets based on it.

Well, You may be right. At least it would be a logical explanation. There are some other differences so why not this one, too.

Most motorcycles for the domestic market have speedometers that indicate up to 10% higher than actual road speed.  That's why there's a market for electronic add-ons to correct the readings.

For the K-bike, there is an potentiometer inside the unit that can be adjusted.  Use a program like Karamba (http://www.k100-forum.com/t2038-karamba-speedometer-calibration-program-tutorial) to provide the calibrated signal and adjust away.  Means taking off the instrument cluster from the bike to get this done -- but you do it only once.  No soldering or playing with the electronics required, except for a special audio cable to adapt the cluster to the PC.
