Race Tech has developed the most advanced valving technology for KTM’s WP 48mm forks found on the 2007-09 big bike KTM SX/ SX-F/ XC/ XC-F models. The G2-R Gold Valve Kit (FMGV 2820G) is designed to optimize the damping by progressive and digressive shim stacks. The OEM stock valving pistons have very restrictive valve ports making it impossible to get the “ultimate ride” results. The innovative design of the Race Tech G2-R Gold Valve Kits optimizes the flow area putting valving control on the shim stacks. This makes for dramatically more traction and control of the bike.The dual port pistons are designed to optimize the loading of the shims while improving flow. G2-R Gold Valve Kits include pistons, shims, valving charts and complete instructions for easy installations. All Race Tech Gold Valve Kits includes accessibility to adjust damping curves with the DVS (Digital Valving System).
