The KLR650 damping rod forks are notorious for being both too harsh and too easy to bottom. This is the nature of damping rod fixed orifice forks. They have to do all the suspension challenges of both road and off-road work by holes used to regulate the flow of fork oil. Until now, all you could do is change spring rate, oil viscosity and damping hole size. The best available was a serious compromise.
These Race Tech Gold Valve Cartridge Emulators change everything! Simply put, Emulators make damping rod forks perform like well-tuned cartridge forks. Emulators are tunable valves that sit on top of the damping rods and are held in place with the main springs. This makes them both simple to install and completely tunable for all conditions and rider preferences.
