We are talking 3 things here
Race Tech 'Gold shock Valves' - are pistons for inside rear shocks
Race Tech 'Gold fork Valves' - are pistons for inside modern cartridge type forks
Race Tech 'Cartridge Emulators' - are cartridge fork emulator valves for old damping rod forks which also happen to be 'Gold' in colour
I have never heard anyone say that the cartridge emulators dont work, are not worth the money or dont totally transform the bike so i dont think so many people can be wrong. They actually won an award for motorcyle product of the year in safety and design or something along those lines way back in 94 or 95, sometime around there. Its pretty safe to say that your not buying a gimmick.
