Race Tech Gold Valve Fork Emulators for RD250/350/R5/DS7 (all) & RD400 (76-78), sold in pairs.Damping rod forks are notorious for being both too harsh yet too easy to bottom. This is the nature of damping rod fixed orifice forks. In the past all that could be done to improve these forks was change spring rate, oil viscosity or damping hole size, until now. Cartridge Emulators make damping rod style forks perform like well-tuned cartridge forks. These tunable valves sit on top of the damping rods and are held in place by the main springs. This makes them both simple to install and completely tunable for all conditions and rider preferences. Track tests have consistently produce lap times that are 1 or more seconds a lap faster while Cruisers and Gold Wing owners rave at the increased control and ride quality.
