So Ive got a 98 cbr 900 and i was thinking about stretching the swingarm. Im not really trying to put a pile of money into this bike since it is older and i plan on selling it in the next year or two. I found these extensions for $250 and wondered if anyone has used them or know if theyre shit or not.

Or if anyone knows of a reputable company that can stretch it for me.
Thanks for the input in advance.
