I have seen/read multiple threads on this subject but they always wind up in some kind of fight.
But anyway heres my question

2002 Zx9R swing arm swaps. I have heard that the 05-06 Zx6R is a direct fit?? Anyone ever do this? i assume I will need swinger, axle/pivot bolts, caliper brakcet wheel and spacers??

And how about fork swaps? Is the 05-06 Zx10 forks the easiest swap? I know that pressing the stem and swapping them is required and a washer or something for the spacing of the top nut?

If anyone could clarify this would be great.

I did this work on my zx7r as part of an experiment in weight reduction....which in my case was significant.

I can say that zx7r guys have used the 05/06 zx6r swingarm...but yes, its very custom, since the pivot axle is smaller diameter and is significantly narrower at the pivot. The rear axle is the same size though.

I measured and weighed a number of kawi swingarms for that project and the 02 zx9r is not heavy given its on a liter bike. I actually put an 02 zx9r arm and rear wheel on my zx7r...it saved me 12 pounds (yes, 12 pounds). The 636 arm is approximately a pound lighter. If you are just going for a cosmetic change, the 04/05 zx10 would be a nice one, but the rear axle bearings are smaller. It is also a little longer. Regardless of what you grab, you will always have some amount of fitting you have to do to line up the chain/wheel.

Forks...swapping stem's may be necessary depending what you pick. Kawi appears to use the same bearing size and press fit size on all their forks (in the ZX family bikes anyway)...that applies to taper or ball bearing styles....they interchange...but the lower seals and dust cap on top may be different. The newer bikes will have less offset and so they might bump into stuff at full lock. Key mounting will be different and the steering stop will be different....nothing insurmountable...but not a drop in.
