Need some dimensions for KZ650 swingarm, Please

I need the following measurements, hopefully someone will have a swingarm laying around that they could measure for me

Looking for :

-Width @ pivot (of swingarm or of width inside of frame)

-Length from pivot center to axle center

-Distance from pivot center to shock mount center

-Width @ shock mounts

Thanks

At pivot 9 in

pivot to axle 18 1/2 to axle center

pivot to shock 17 en

shock width 10 1/4

Thanks, appreciate the info. Trying to plan a project and I have 2 ZR swingarms that I can use, Looks like the one from a 550 will go in w/out machining. The 750 arm is 9 1/4 at the pivot.

I have a GPZ 750 swing arm in my 650, It uses a GPZ 550 bearing sleeve and the 650 pivot bolt.

Mark,

Thanks for the info.

Your bike looks great, your concept is not all that different than what I have in mind. You seem to have gone for upgraded performance while keeping the bike somewhat retro. I've bought a bunch of cool parts over the last 5 years about it's time to start using some of them.

I'm looking to start with a 650 chassis and add ZR550 running gear (forks,swingarm,brakes,Rr wheel,18" Concours Fr wheel),Ohlins shocks,Kerker. All stuff I have sitting around. The only piece of sacrilige on this project for the KZ crowd will be the motor........I have a Katana/GSXR750 air/oil coiled motor I bought a while ago that I want to use. It should easily make 90hp stock. The motor is the main reason I am looking to use a 650 chassis instead of a 550. I know that it will go into a 550, but it looks crowded.

1st pic is of a bike I found on a Euro KZ site, I want to end up with something very similar :

2nd pic is a GSXR/GPz550 I found a pic of also:

I can say with absolute certainty that you can make just about anything you want work out. You've got the vision, collected the parts and are ready to embark on a life changing odyssey. In the last 5 months, I've done things I never knew I could do, just because of the need to overcome the obstacles in the path to my dream. Best of luck, you have some extremely knowledgable people here to help you through the tough parts.

i need help fast, the way you have set up your mono shock i done the same but iv been told by someone in the twin forum
"If I interprete your monoshock-system well, I expect it wouldnt work. With this geometric you dont have a progressive system, it would be degressive and by a deep movement of the rear swingarm it would collapse. The Geometric should be of the type, that a up-moving swingarm an increasing force against the movement produces. Your geometric system doesnt it."

The GPz550/GSXR motor bike is just something That I found a picture of. I didnt build it.

It looks like you have to raise your lower shock mount so that it would be positioned above the chord line from the rear axle to the top shock mount, and that the lower mounting point of the shock would never drop below the chord line, even at full compression.

raise the lower shock mount? the shock mount is fixed onto the swing arm. iom using a buse shock because its the strongest.
