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. Until now, all you could do is change spring rate, oil viscosity and damping hole size. The best available was a serious compromise.
The Gold Valve Cartridge Emulator is another one of the outstanding inventions from Race Tech’s Paul Thede. 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.
Customers report using Emulators consistently produce lap times that are 3 to 4 seconds a lap faster.
Dirt Emulators - FEGV 3004
Race Tech’s latest vintage model fork kit fits vintage Yamahas with 34mm KYB forks. The stock damping rod does not have a piston ring and thus does not create consistent rebound damping. Race Tech’s unique Piston Ring design seals the fork chamber for better damping. FEGV 3004 includes FEGV 3001 Emulators, FPPR 253417 Piston Rings and FPEV AD3003 Emulator Adapter for easy drop-in installation. Most common bike models are: 1973-78 Yamaha DT/ MX/ SC/ YZ.
