An expert got paid $4.80 to identify this. Become an expert today.

These are the input, intermediate, and output shafts from a BMW R1100 or R850 motorcycle transmission from model year 1997-1999. I am currently rebuilding a 1998 trans, and those shafts are exactly the same gears and bearing numbers as the ones I am working on. I also work in the parts dept. of a BMW dealership, so I'm pretty familiar with those as well as other BMW parts. Go to Max BMW's online parts fiche and lookup R1100gs or any other R1100 model from 1997-1999 and you'll see these trans shafts.

Well. I looked a little further at 5 speed Airhead transmissions that I suggested earlier. The middle shaft that looked to me as from one of these is not correct. The shifting fork ramp is in the wrong place and so definitely wrong. I will try to see if I can find something about early Oil Head 5 speed BMWs. But I don't have any experience with those anyway.

Okay, thanks for letting me know!

Do you think these 3 shafts are from the same transmission? The middle shaft is called a layshaft and sits between the input shaft and the output shaft. Well, the middle shaft looks like one from a BMW motorcycle 5 speed made sometime between 1974 and 1995. It has the correct bearing to be from one of those. But the 2 end shafts are not from this vintage. There are differences in the models I think the middle shaft is from. If so it will have to be taken apart to identify which specific part of the vintage I have suggested. The early Oil Heads had a 5 speed also and these may have similar parts to the Airheads 5 speed I mention. If you really think these are from the same transmission I guess it may be from one of those. Don't know if I can find the info about those but I'll look a little into it and if I come up with anything I'll post more for you.

I sent you a message. I'm not positive that they are a set, but they were in a box together.
