YSS Progressive Wire fork springs with a firmer design than stock.
YSS fork springs are made of high quality silicon spring steel. This allows the thickness of the wire to be reduced, which makes the spring more active and thinner, but at the same time effectively prevents twisting of the spring.
To minimize noise and improve oil flow in the fork, the springs are fully polished and ground on the top and bottom.
2 springs are included for a complete fork conversion. SPRING TYPE: PROGRESSIVE LENGTH: 565MM DIAMETER 1: 25.5MM HARDNESS 1: 3.8 N/MM HARDNESS 2: 5.2 N/MM LEFT AIR CHAMBER: 180 MM RIGHT AIR CHAMBER: 180 MM RECOMMENDED VISCOSITY: 10W
