Relieving the front fork internal pressure
If the front fork initial movement feels stiff during a
run, relieve the front fork internal pressure.
– Elevate the front wheel by placing a suitable stand under
the engine;
– Remove the air bleed screw “1” and release the internal
pressure from the front fork;
– Reinstall air purge screw “1”.
Air bleed screw: 1.3 Nm (0.13 m•kg, 0.95 ft•lb)
To improve the front fork performance, and adapt it to different road conditions, driving style and rider’s weight, Fantic
features springs with different load coefficients which can be purchased from authorized dealers.
