Super easy install - undo top cap then drain oil completely and remove base bolt. The kit slides in as a complete replacement supplied with spring installed all ready to go!

Fork Spring Rate Recommendation

KG	Spring Rate
35-40	6.0 N/mm
40-45	6.5 N/mm
45-50	7.0 N/mm

55-65	8.0 N/mm
65-70	8.5 N/mm
70 >	9.0 N/mm

General Riding and Motocross Applications.

These recommendations are a guide only as fork Springs are weight and speed dependent. For example a 44 kg A Grade Pro level rider falls into the 6.5 N/mm category but may well be better suited to a 7.0 N 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.

Also note we have had great results using one spring down for C level riders or absolute beginners on the 85cc machines. E.g. - 42kg rider running a 6.0 N/mm spring for a plusher ride.
