I am pretty sure the sidecars are allowed to change up gears from the start, but once up to speed not allowed to change down, ie they have do the whole race, other than the start, in one gear. It follows then that what ever cams they use should be able to give a pretty wide power band. On the other hand the back tyre is spinning most of the time, that would effectively be a constantly variable transmission. Could be interesting on the road.
it's not a bad thing till you throw a KLR into the mix.
those cheap ass bitches can do anything with ductape.
