Title: K75 Small OEM tragkorbs
Post by: bluebossa on October 10, 2017, 03:25:04 AM
Anyone know what capacity these are - they seem weedy compared to the ones I had on my R850R..


What capacity are they, versus the standard bigger ones?


Thinking about the less is more argument... where luggage is concerned and the fact that the bigger tragkorbs you have the more Shit you carry!

Those are called "City Cases". I can't tell you the internal capacity compared to the touring case.
The smaller size makes it easier for those that are allow to lane split while commuting to work.
But on the flip side, they limit how much you can pack and carry for touring.

They offer 0.7 cu.ft or 0.2 cu. meters each.  I have a pair and find them really conveniently sized although a tad small.  They just fit a laptop for work or I can run a small errand to the grocery shop for milk and bread.  My Ogio NoDrag backpack has now completely taken over as primary commuting transport for me.

Now that you're making queries about what to carry on a long trip and how to carry it, does that mean you solved the starting issues and the bike is now running well?

Any idea of the size of the big ones

Hey Laitch, no different bikes. The one here still isn't running...

Which Mach? How comfortable is it in traffic during warm weather? It looks to be useful for lane-splitting minimalists who have yet to unburden themselves completely from the tyranny of things. :giggles

The Mach 5's having accommodation for a spare face shield is attractive. I switch from a Pinlock shield to a plain face shield at night to reduce headlight glare.

Are the city cases anymore "friendly" to attach?  I keep forgetting how to easily attach the jumbo OEM cases I have.  Once they are positioned properly, they slide in placed like greased butter--finding that proper position is the hassle.  I remember reading a post on this forum for the correct technique but apparently didn't save it.  Can someone post it up?

No, the City Cases are not easier.  They still have the same problems as the System 3 cases when fixing them to the frames.  The locks are less convenient than the Systems 3 cases.  They are the old design.

It is a Mach 5.  I originally owned a Mach 1 and liked it much better.  The zipper on that original backpack died after many years and Calloway Golf gave me a free replacement (great customer service).  I love the features of this backpack.  It's very comfortable in hot weather because it provides air pocket on the back, and it is fully aerodynamic meaning it is not noticeable at speed.  The only complaint I have is the interior pockets are much worse in the Mach 5 than the original Mach 1.  It's one of those cases where the manufacturer had to tweek the original product and just made it worse.  I find that I don't use the shield holder and it reduces the available space for me.  I have a pinlock visor on my Shuberth C3 Pro as well as a flip down sun shield.  I like the expansion zipper  that was introduced with the Mach 5.

city cases are great for day trips.  ez on and off, hold "just enough".  look a little sleeker on the bike.  95% of the time, these are what I use.


2% of the time i use the enourmous integral cases.


3% of the time i use a tank bag.

In regards to the difficulty of R/R tragkorb cases, I found this on the BMW MOA forum from 2003.

1. Open and unlatch bottom latch.
2. Lift up and tilt bottom out.
3. Slide back a little.  (Lifting the back of the tragkorb makes it easier to remove from the rack)
    It will come right off. Putting back on is the exact opposite.
   
I add the "lifting the back ..." as it sure makes it more friendly to those who seldom remove/replace tragkorbs.  I also added a silver mark from a Sharpie on the top of the rack at just the right placd so once I am ready to install, I position the tragkorb clamp onto the rack, with the back slightly elevated.  Works like greased butter.

Thanks guys, nice details..

So if the City Cases (which I have) are .7 cu feet or .2 cu meters - how much the Bigger OEM ones are??

Wondering how much more they hold % wise... Thanks??

I've got to review my You Can Learn Metric Measurement Despite Your Native Education correspondence course. I can't seem to get those two values to balance. Is the updated version available?

Looks like RBM got his decimal places mixed up... .02 cu metres


Any idea what the Big ones are in comparison - that's the answer I'm after...??

My idea is that they're around ±28 liters. Be aware that there are three case types. The Type 3 has outward facing lock cylinders in the latches combined with the largest capacity of the three. My bike has those.

Thanks Laitch - another conversion!
So if that's accurate - are these units per Case do you know, or for both?


City tragkorbs - 20 Litres approx
Full size tragkorbs - 28 Litres approx


So just nearly 30% larger...

The estimate comprising my idea that was a response to your request for ideas was for a single case volume. What I can tell you accurately in the style of mlytle is that I use my tank bag 100% of the time, my side cases 98% of the time, my top case 5% of the time, and that the one side case will easily hold the contents of the standard, brown-paper grocery bag commonly found in the grocery stores under the spacious skies above the purple mountain's majesty, the amber waves of grain and the fruited plains.

Please refer to page 9 in this BMW Accessory Brochure from John's Garage (http://www.beemergarage.com/documents/equip932.pdf) for the capacity details.  The City Case is 0.7cu.ft. and the System 3 Case is 1.23 cu.ft. PER CASE.


I apologize for getting the decimal point in my metric conversion wrong; I rarely work in US units of measure.  Using a better volume conversion tool so that I don't throw off the decimal point, the City Case is 20 litres and the System 3 Case is 35 liters PER CASE.

Big enough to hold a baby elephant.  The downside is the K75 bikes are not powerful enough to tote a baby elephant.

Wow! That means I can put more stuff in mine. :giggles  But I'm head right out there now with a measured pail of water to verify this, Robert, if I can fill one faster than the patched holes leak out.

Depends on whether the wombats are the Northern hairy-nosed or Southern hairy-nosed.


Baby elephants are estimated to weigh around 600 lbs.
Title: Re: K75 Small OEM tragkorbs
Post by: Martin on October 14, 2017, 05:22:06 PM
I'll be using the standard Northern hairy nosed variety, due to the scarcity of Southern hairy nosed variety in these northern realms.

Dry uncooked rice is less messy (funerary urn makers method. One lb of um ... live weight = 1 cubic inch of cremains).

Cremains. That's a great word! I need to use it at the next barbecue. "I can't finish my second helping. Who wants these cremains?" 

Water can only help the interior of those cases. :giggles

Sadly we usually use plastic bags here in our sunburnt country, A land of sweeping plains, Of ragged mountain ranges, Of droughts and flooding rains.

But they fit too :)

How do those wombats know if they are North from South?  Is there a DMZ between the two areas?

You can tell them by their accents. Northern ones also have longer nose hair.

Thanks RBM - no worries... so 40 litres v 70 litres for both? Quite a difference really..
