I am toying with the idea of getting an extra set of rims for supermotard for my XR400R. I have searched here but no results. Anyone have experience with this. I don't want to spend a fortune on this. I now have more or less two kits to convert the bike to electric start. I got the crank extension from a company is Switzerland. It looks like it needs a different bearing for the ring gear, need to look into this next week. Anyone know the deal on this?
