Product Description

Genuine front brake caliper piston kit (Piston Assy, Caliper) supplied directly by Yamaha complete with its matched OEM fluid pressure seal and dust wiper seal ring. Specifically designed for Sumitomo 4-piston monoblock front brake calipers, these pistons feature a hard-anodized surface treatment to resist heat fading, prevent corrosion pitting, and ensure fluid-tight sealing under high braking pressures.

Fitment Details

Unlike bare piston replacement options, the Genuine 4XV-W0057-50 factory package includes the original inner square-profile fluid seal and outer wiper seal needed for a full caliper piston service. Ensure caliper piston bores are fully cleaned of old brake fluid varnish and oxidation before installing the new seals and lubricate all mating surfaces with clean DOT 4 brake fluid or red rubber grease during assembly.
