This is how the factory riders start! The factory start is mounted directly on the fork. Before the start, the fork is dipped and fixed in the desired position to shift the center of gravity forwards. This to a large extent prevents the front wheel from lifting at the start, thus providing greater traction and perhaps securing you a hole shot or two. The first time the fork dips, the device releases automatically and the fork returns to normal function. Provides more traction when starting. Made of high-strength aluminum. Elegant anodized surface. Pure race feeling. Mounted directly on the O.E.M. fork. Two different selectable preloads, without additional effort in mounting. Simple mounting of the fork ring due to two part design. No longer necessary to remove the fork.
