swingarm swap into kz650

looked thru all i could about this one, picked up a rolling chassis from a 85 ninja 500(?) everythings in good shape and was going to stick the swing arm into my parts 78 kz650, was wondering if anyone had done this or had any info i may not know as to it not working.... thanks

The closest I've heard of is the swap of an EX250 into a KZ400. My questions would be why do you want to make this particular swap other than you happen to have the parts? What do you hope to gain by doing it? Do you plan on making it a monoshock or welding tabs on to make it twin shock?

The reason I ask is that I don't see any particular advantage to that swap. The EX is steel also, correct? So you're not going to gain much in weight reduction, I think. Your EX arm may not be up to the task since your Kz is about 30Kg heavier than the EX. Also, I think the stock tire widths are the same so you gain nothing there.

All in all, it doesn't seem worth the effort to me.

yup, basically cuz i have the parts, or access to em... but yeah, your right, too much work for not much of an improvement

which wheel do you like best? if its the ex, see if it will fit the kz arm?, if not, do the swingarm swap.
also if the ex arm is longer, you might find that desirable as well. its your bike, modify it the way you want itB)
