motorcycle on a stand so that the front wheel is off the ground. Now try to
move the fork forward and backward. To adjust, loosen the five clamp
screws 1 of the top triple clamp and turn steering stem bolt clockwise
until there is no more play. Don't tighten the steering stem bolt all the way,
otherwise the bearings will be damaged. With a plastic hammer, lightly rap

Changing the spring preload of the shock absorber

KTM sets the shock absorber for a driver only, weighing approximately 75
kg (165 lb). If you want to take a passenger with you, of if you weigh
considerably more or less than 75 kg (165 lb), you should change the spring
preload accordingly. This is easily done.
NOTE:
– Before changing the spring preload note down the basic setting, e.g.
how many threads are visible above the adjusting ring.
– One rotation of the adjusting ring
approximately 1,75 mm (0,07 in).
