YSS SUSPENSION Rear shock absorber piston kit 789.03.44

YSS pistonkit of original motocross struts.

The piston kit contains a piston ring and shims.

This piston kit will prevent conditional suspension slump heat on the factory equipped strut.

The factory pistons are made of sintered metals, the cylinder of aluminium.

These two materials have fundamentally different temperature behavior: Aluminum expands more than sintered metals. This creates excessive deviation from tolerances while driving, the piston ring cannot seal. The result is a noticeable loss of damper performance.

YSS offers the same material with its aluminum piston, so the thermal properties are identical, the piston extends in drive mode as tightly as it does from the cylinder, tolerances remain the same, piston rings seal effectively outside. The result is much better response, better damping. The attached devices are tuned to a perfect valve function. The piston kit should be run with the weight tuned YSS MX rider spring to its full developing potential.
