Spring Rate Recommendation
General riding & Motocross applications
These recommendations are a guide only as fork Springs are weight and speed dependent. For example a 72 kg Pro rider falls into the 0.92kg/mm category but may well be better suited to a 0.96kg spring due to the much higher corner entry speed and the ability to hit large bumps at high speeds. Please note this guide is for rider weight ‘without’ gear.
Please note we have had great results using one spring down for Veteran/ C level riders on the 450 machines. Eg. 90kg rider running a 0.96kg/mm spring for a plusher ride.
