Stage 2 Upgade includes everything in Stage 1 plus Racetech Gold Valves Custom Valving Kits. They are designed to break through the limitations of stock piston designs. Research has shown that the stock piston ports induce unnecessary harshness. Gold Valves are designed to reduce piston restriction so harshness is dramatically reduced. This also allows the valving stack to be personally tailored to the individual rider. Tests have proven that bottoming resistance is actually increased as the harshness is decreased. Traction is also improved. The key is a careful combination of the Gold Valve itself and the valving stack. Custom setups are computer calculated with the Digital Valving Search (DVS)™ Developed and refined for over 18 years, this system calculates the proper setup for the individual rider including clicker settings from over 300,000 possible combinations.
