Race Tech’s newest Fork Gold Valve Kits are for the Showa BPF forks found on the new 2011 Kawasaki ZX-10R and Harley-Davidson XR1200 (FMGV S3901C), and the 2011 Suzuki GSX-R600 (FMGV S3701C). The kit addresses issues with the stock BPF design, which has an oversized, yet very restrictive singular piston that is required to flow more than 10 times the fluid of a standard cartridge, creating harshness and contributing to fork chatter during braking, according to Race Tech.
Race Tech’s Gold Valve improves the flow characteristics dramatically
Travel is increased to improve bump absorption, particularly under heavy braking
Increases front end trail, improving stability and grip
Kits make the bottoming process more gradual, decreases front brake chatter and improves traction
