Swingarm extention basics

Cool. I've been wondering about it for a while. I guess it'd be nice to do some welding and do some tests.

looks much better without that big ol ugly stock brace on top of it!

Ya it does look alot better with the top brace gone, But the reason I did the busa arm is because they fit the kz frame with nothing more than some pivot bolt reducer bushings. Pretty much all of the early model gsx-r's and all of the busa arms even the second gen busa fit the kz frames with just a simple bushing set up. It is a little more work with other late model sportbike arms.

Good stuff man! we all appreciate your time to document this info.

thanks alot for that little tutorial mike. :evil:

very much appreciated.

documenting does add to the time.

i have not had my hands on a busa swinger,YET :woohoo: .

but now that you have explained it so thoroughly i will be lookin for one to mod.

so is the first gen's (1999-2007) the best for modding for a kz?

Thanks Leon. Ya the arm I did was a first gen 99-07 but the second gen busa arms are just about the same, the only real difference is gen 2 has smaller dog bone linkage bearings,instead of a brake bar for the rear caliper it uses a brake block on the inside of the arm and the caliper braket slips into it and the inside of the tubing when you cut the adjuster blocks off there is a webbing inside the arm where the first gen is hallow. Both are good for modding to the kz frame!

A stock busa arm is 22.5 inches from center of the pivot tube to the center of the axle adjuster slot.
