BASIC SUSPENSION SETUP FOR THE WEIGHT OF
THE DRIVER
To achieve maximum handling performance and to prevent the fork, shock
absorber, swing arm and frame from being damaged, the basic setup of
the suspension components must be suitable for your weight. At delivery,
Husaberg's offroad motorcycles are set to accommodate a driver weig-
hing 70 - 80 kg (wearing full protective clothing). If your weight exceeds
or falls short of this range, you will need to adjust the basic setup for the
suspension components accordingly. Minor deviations in weight can be
compensated by adjusting the spring preload. Different springs must be
installed for larger deviations.
CHECKING THE SHOCK ABSORBER AND SPRING
You can establish whether or not the shock absorber spring is
suitable for your weight by checking the riding sag. The static slag must
be correctly adjusted before the riding sag can be determined.
DETERMINING THE STATIC SAG OF THE SHOCK
ABSORBER
The static sag should be as close as possible to 35 mm. Deviations of
more than 2 mm can strongly influence the motorcycle's performance.
Procedure:
– Jack up the motorcycle until the rear wheel no longer touches the ground.
– Measure the vertical distance between the rear wheel axle and a
fixed point (e.g. a mark on the side cover) and write it down as
dimension A.
– Place the motorcycle on the ground again.
– Ask a helper to hold the motorcycle in vertical position.
– Measure the distance between the rear axle and the fixed point again
to establish dimension B.
– The static sag is the difference between dimensions A and B.
EXAMPLE:
Motorcycle jacked up (dimension A) . . . . . . . . . . . . . . . . . . . . .600 mm
Motorcycle on ground, unloaded (dimension B)
. . . . . . . . . . .– 565 mm
Static sag . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .35 mm
If the static sag is lower, the spring preload of the shock absorber must
be reduced, if the static sag is higher, the spring preload must be incre-
ased. See chapter "Changing the spring preload of the shock absorber."
DETERMINING THE RIDING SAG OF THE SHOCK
ABSORBER
– Have a helper hold the motorcycle while you sit on the bike in a
normal seating position (feet on the footrests) wearing full protective
clothing and bounce up and down a few times to allow the rear wheel
suspension to become level.
– Stay on the bike and have another person measure the distance bet-
ween the same two points and write it down as dimension C.
– The riding sag is the difference between dimensions A and C.
EXAMPLE:
Motorcycle jacked up (dimension A) . . . . . . . . . . . . . . . . . . . . .600 mm
Motorcycle on ground, loaded (dimension C)
. . . . . . . . . . . . .– 510 mm
Riding sag . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .90 mm
