Title: Project DevilK75S
Post by: Devil K on June 16, 2016, 01:46:10 AM
This thread will be dedicated to turning my 1994 BMW K75S into a cafe bike... more or less at least.

When I first got this bike I knew that the transmission was bad. During repairs i soon found out that the drivshaft was bad as well. Since then i have given the whole rear end of the bike a complete overhaul. New used 5 speed transmission, custom driveshaft, the previous owner installed a new used final drive (I wonder if I can find another final drive with taller gears?). Shortly afterwards though I snapped my clutch cable. I have found another one on ebay, just waiting for funds to order it.

That does not look like a K75S.  Looks like a base model/75C.

What is the VIN?

It's a hybrid.
Rear brake would be a drum,the final drive ratio will by lower ratio too.Forks are the next distinction.
Dressed as a C.

A stock K75 wouldn't have bar weights either. It's hybridized, like Dude said. A C would have a slightly differing headlight assembly, too. It looks to me like a Standard that got a C-bar. It's the perfect candidate for cosmetic surgery. Pretty good pics, Devil.

So it has a c bar, does that mean that it's a mid/high rise handlebars? The first digits of the vin are 1057

I thought for sure the rear disc brake was a give away
Title: Re: Project DevilK75S
Post by: Devil K on June 21, 2016, 09:04:20 PM
Not to mention it has a 17 in the rear. It's deffinetly not stock but I'm 99 percent sure that it's an S.

Wrong first digits.  The VIN usually refers to the last 7 digits in that long series.   The first part is other codes saying where it was made and other info. When I said first four it was the first four of that 7.  What are the last 7 digits of your vin?

  VIN Last 7 digits should be 0154xxx.  Mine was the first 94 S made.  Vin 0154291.  Yours would be higher than 291.

You can also put your last 7 into realoem.com and it will tell you what it is.

Yep, those are barred owls all right.

I think that you guys are right. It's a standard
Title: Re: Project DevilK75S
Post by: Devil K on June 22, 2016, 01:06:17 AM
0134935 are the last seven digits.

So then let me ask you guys this. If I ordered a low rise clutch cable will it still fit these C handlebars? Really wish someone hadn't already had at my bike, now it's even harder to find parts for it.

At maxbmw there's a cable labeled "low/medium applications." If that is the one you bought and you do have a C-bar, let not your heart be troubled and avoid wasting valuable cursing time by wishing for the impossible.

Actually,  since we have confirmed your do not have an S model,  looks like you have a stock base model.   No mods.  Easy to look up parts for now.
