· Race-developed and tested in World Superbike, World Supersport and AMA Superbike competition · Improved design features a fork cartridge that uses a sealed, one-cylinder piston chamber that allows oil flow only through the shim stack on the cartridge piston when compressed · Kit uses a larger, 30mm diameter piston that flows more oil that allows for a wider range of adjustment · This provides immediate suspension response and generates optimal suspension oil pressure all the way through the fork damping sequence · All damping adjustment knobs are at the top of the fork caps for easy suspension tuning (compression on left fork leg, rebound on right leg; both have spring preload adjustment) · For use with OEM fork tubes · Used only 3 times · $850.00 OBO plus shipping · Forks are sprung for a 190lb rider done at Boulder Motorsports email: [email protected] or text 303-330-6794
