The shock will bolt right up.
Although it is longer than most shocks and puts the swing arm at a huge angle. If you have an extended S.A. you can make it work.
The shock is longer but has less actual shaft travel.
so you get the ride height but not the travel. A KTM 50 feels plush like it does b/c of the angle the shock sits. Giving it good wheel travel.
If you have a stock set up and am wanting a better feel in the back for less cash. check out the Kitaco shock at
www.hondaminitrail.com , I think it sells for 100 or less. Its a great feeling shock.
