650 extended swingarm

i put a 1985 gsxr750 arm in my gpz.no mods it was 238mm wide at mounting same as gpz. and a couple inches longer and i used a gsxr1100j 18 inch wheel with a 170. i dont know how wide your mounting area is but it was cheap and no effort. just had to cut off the monoshock mounts and weld tabs for the shocks. www.streetfighters.com.au/forum/topic.asp?TOPIC_ID=5630

Thank you for the post, i like the way it turned out...so then let me ask you this.

The rim of a stock 650 is not wide enough to handle anything above a 130 tire, if i understand it correctly. So, should i look into getting a GPZ rear wheel. How would that fit on a GS1100 swingarm that i have?

Hey ZeeEuro a cop cast wheel is the widest that look stock on a KZ. I'm using on with a 150 in a 84 GPZ750 arm on my KZ650. The stock wheel is 2.15 wide and the cop wheel is 2.50.

Thanks Mark, that really helped. One more question: how does my 81 GS1100 arm compare to your the 84 GPZ750 arm as far as length, etc?

I think their close. The GPZ is 1 3/4 longer than 650 arm. I put the whole mono-shock set up on my bike but you could have shock brackets welded on. I used GPZ 550 bearing sleeves in the 750 arm and the stock 650 pivot bolt.
