I almost hate to say it, but with some connections, mine was free.
It will cost some for the conversion, though.

Lucky you - I just paid $215 for one.
From the IBMWR.org site. Now the fun begins.

I'm curious. Could someone share what the deal is about 1200c final drive conversion?
Do you put this on a K1100?
I have no idea what it's all about and why.

Gwen - it's on K11 here somewhere. IIRC, the 12RC rear has a different final drive ratio and lets you install a wider tire. Found this from Gary, but I think he just changed the gears: "By the way, I changed the Final Drive Gears with R1200C Gears, they fit straight in no modifying or machining and it took 500rpm's off 5th gear at 100kmh... just perrrfect!"

I want the six speed transmission for my K. I was told it bolts right on.

Yes, new bearings, sealings and a lot of shimming.
Tooth backlash must be adjusted, contact pattern and preload for the wheel bearing must be adjusted.

Just about the only thing I take to the shop. I don't have any special tools that you need to disassemble and reassemble the rear end.
Also, the purpose doesn't have anything to do with tire size. It is a ratio change, equivalent to approximately 11%. Fewer rpm all the time. I have always felt that these bikes were geared from the factory for towing trailers.

I suppose you are talking about the transmission on the K12RS/GT.
Yes, it will bolt on, but you'd be better off buying a K12.
The bellhousing is different, the frame is different, the bike is different.
With enough money and engineering you can adapt anything to practically anything. Mounting a complete K12 running gear wouldn't bolt up either.
A K12 ENGINE will bolt up with minor changes.
