Topic: Yet another swingarm swap question

[greenjeans]

Ok, for the last hour and a half I've been going though swingarm posts and can't find the post that had year & models for easy swaps....

I have a 1972 CB750K

I would like to fit a longer swingarm on there without any machining etc...  pipe dream ?     Does anyone know definitively which years would bolt right up
to my '72 and be 1 to 2" longer ?    I plan to run the original drum on the back. 

Can anybody point me in the right direction as to which year and model number I could search for ?       

Thanks,  I'm back to the search....

Think the F1 is longer, know for sure the F2 is longer. They both fit, at least to my knowledge.

Good luck.

you can fit a DOHC swingarm. If you do a search there are pics. No machining but you do have to cut a few inches off the pivot. Rear spacers are up to you but you can figure it out with DOHC spacers since some of them share a wheel with the SOHC f2/3

When you say "cut off a few inches off the pivot"  what are you talking about ?   
Is the DOHC frame wider by that much ??

Haven't searched DOHC swingarm yet....off to the archives

I threw my F2 swing arm on a 76 K model just fine and I know its longer than the one that came on the bike.
