YSS linear fork springs with a firmer design than the original.
YSS fork springs are made from high quality silicon spring steel. This makes it possible to reduce the thickness of the wire, 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: LINEAR Length: 300 mm DIAMETER 1: 36MM HARDNESS 1: 9.5 N/MM LEFT AIR CHAMBER: 110-130 MM RIGHT AIR CHAMBER: 110-130 MM RECOMMENDED VISCOSITY: 10W
