The factory start is mounted directly on the fork. Before the start, the fork is compressed and fixed in the desired position to shift the center of gravity forward. This prevents the front wheel from lifting at the start, thus providing greater traction and perhaps securing you a holeshot or two. The first time the fork dips, the fixing is slackened and the fork releases automatically. With additional fork protector reinforcement for more stable attachment to the fork leg (SXS13540100 only).
