Product Description

KYB AOS (twin chamber) front fork replacement free piston kit. By changing the material from stock plastic to anodized aluminum alloy, the strength is increased and it is less likely to break.

The standard type is designed to optimize the pressure balance so as not to affect the feeling of the stock product.

The LT type is as lightweight as possible and friction is reduced. By reviewing the pressure balance, a more comfortable feeling is realized and the burden of riding is reduced. In addition, it can be changed to the same feeling as stock by adjusting the amount of oil. The overall movement also has a progressive feel.
