Re: WTB: SWING ARM EXTENSION for cbr 954
hello, punch in your bike to google, look for people who specialize in your model or swing arms. they may not be a kit, so you will have to figure out what you need. generally you need the arm to fit at the pivot point ,shock and brake mounting, axel adjustmentand longer chain(hugh!) with maybe a tensioner roller. chain lengths are usually 100 to 108 links. longer chains whip themselves to death, outside of wasted power. the right bike frame geometry in original design is when to decide these things.function before beauty, in function is beauty.
