The Spring Conversion Kit is a complete replacement cartridge assembly for your current TAC Air Fork setup. It is designed to completely remove all the pneumatic system from your current Showa Motorcycle Forks and replace it with a traditional preload adjustable steel coil spring and cartridge setup - compression damping in one leg and rebound damping in the other.
Parts included in the kit:
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.
Also note we have had great results using one spring down for Veteran / C level riders on 450cc machines. E.g. - 90kg rider running a 0.96kg/mm spring for a plusher ride.
