Spring Preload Adjustment

The front and rear shocks have a spring preload
adjustment. Suspension spring preload may be adjusted
to suit different riding conditions or vehicle payloads.
Uneven adjustment may cause poor handling of
the vehicle, which could result in an accident
and serious injury or death. Always adjust both
the left and right spring preloads equally.
