Spring preload<br />
Setting<br />
It is essential to set spring preload<br />
of the front suspension to<br />
suit the terrain. Increase spring<br />
preload for riding in rough terrain<br />
and reduce if the terrain is level.<br />
It is essential to set spring preload<br />
of the rear suspension to<br />
suit the load carried by the motorcycle.<br />
Increase spring preload<br />
when the motorcycle is heavily<br />
loaded and reduce spring preload<br />
accordingly when the motorcycle<br />
is lightly loaded.<br />
Adjusting spring preload<br />
for front wheel<br />
Make sure the ground is level<br />
and firm and place the motorcycle<br />
on its stand.<br />
Make sure there is no load<br />
on the motorcycle; remove all<br />
items of luggage, if carried.<br />
Hold the motorcycle upright<br />
and measure distance d from<br />
bottom edge 1 of the outer<br />
tube to front axle 2.<br />
Apply the rider's weight to the<br />
motorcycle.<br />
With the assistance of a<br />
second person, measure<br />
distance d between points 1<br />
and 2 again and calculate the<br />
difference between the two<br />
readings.<br />
Load-dependent adjustment<br />
of spring preload<br />
Negative spring displacement<br />

Your motorcycle's handling<br />
will suffer if you do not<br />
match the spring-preload and<br />
damping-characteristic settings.<br />
Adjust the damping characteristic<br />
to suit spring preload.<br />
To reduce the difference (increase<br />
