I have already done some research, but will be spending a lot more time as I get into this more - I have my eye already on a pre-74 (1971 /5) tranny - apparently after '74 the kickstart lever wasnt that well built.

I'm used to low compression kickstart bikes, and this project will be a Sunday morning/Friday night poser bike (I admit that!) so, I don't think I'll be too concerned about the kick!

I thought that the best way was a post 85 R-airhead monolever swingarm and final drive, mated to a 3 spoke K bike should only require a bracket/space etc for the disk brake - so thanks for confirming that Anton - and YES I have been reading your site too!

Hmm...changing the clutch/flywheel etc may be a drama - but I may have to replace the original clutch anyway on the donor bike, so maybe not?

Thankyou Alfons for the info as well - the BMW-Ducati conversion is brilliant. I have a picture somewhere of a guy with similar swingarm and front end, but with no fairing. Ill post it later.

Just bought a spare R65 triple tree - so I'll start researching what front end I can put on the bike (the original will be sold, its a single disk with a pitted fork).

anyone know the fork diameter on the R65?
Hi it is Germany again here,

R 65 forks are 36 mm just like the forks used in all the type 247 airheads. I would suggest considering K 100/K75 forks as these are made for bikes which are not as heavy as the K 1100s, so the forks springs might work well in a much lighter bike.
If I were you I would keep an electric starter since they are more convenient than a kick starter, particularly since the kick starters of the later series are useless, and with a /5 gearbox you would be restricted to the heavy flywheel.
Keep us informed
