2016 KTM 65 SX
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 forward. This to a large extent 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 device releases and you are ready to race!
