Hi there, I'm not often here but as I sometimes saw pics of GS conversions on BMW K75, here is mine, juste finished: The purpose was not to make another off road monster bitza but to build a K75GS that BMW could (should) have done and commercialized in the mid 80's, using nothing but original parts, melting the qualities of the K75 ( smooth, reliable, highway proof, comfortable for pilot and passenger) with the GS ones ( off road aptitudes, easy and efficient on mountain twirling roads ( I live in the French Alps). The base is a '85 K75C, with 100k kms, the engine was overhauled. A K1100LT gearbox, paralever and bevel drive, with the K11 shock, drive a R1100GS wheel. I first planned to fit a R100GS bevel on the K11 shaft, and use a R100GS wheel with drum brake, but that would need machining, the R100 intake shaft beeing longer than the K1100 one. So the R1100 rim is a bit wide at my opinion, visually. The front end comes also from a R100GS, but with a twin disc brake, using a right slider machined to fit the left stanchion and wheel axel to provide its fixings for the extra caliper. Calipers, discs and master cylinder are still the K75 equipment, as the drilled discs save weight compared to the plain surface of the R100GS disc. The headlamp carter is cut to fit the original K75 instrument cluster above, hiding between the GS windscreen and bars. The seat receives a new foam and cover, referring to the original R80G/S pattern, with the Alpinwhite paint sprayed on the body. The exhaust is stock, that allows to keep the saddlebags mountings in place and my ears in peace. I don't expect to ford rivers anyway. But who does really? After 18 months building, it now runs fine...handling is great on the road, as my R100GS is, but with a better frame rigidity and better brakes. The main difference is about the engine character, the K75 gives its best after 4500rpm, when the R100 is better under that, but the 15 extra HP allow to ride pretty fast. I've not really tested it off road yet, but that will come. The reactions of people seeing that bike in the middle of the others in the workshop makes me thing that the goal is attempted: they don't notice it at first: "Oh, you have R1100GS...and an R100GS Paris Dakar, great! And a K1, wahou! And a R100RS..."etc. Then "Oh, and this is a...no, it"s a...but...no? Yet it has...But it's a...with a?! Er, tell, what's this model exactly, I never saw it?"
