Yamaha WR 250 F Forged Replica Piston Kit - Vertex Pistons (20-24). A direct-fit forged replica piston kit engineered to replace worn components and restore reliable performance in WR250F models from 2020–2024.

This Vertex kit provides an accurate replacement option built to the specifications needed for close bore tolerances. Exact fit A, B or C piston options match your cylinder bore to help reduce blow-by and oil consumption while maintaining intended compression and combustion characteristics. Each kit ships complete with piston, rings, wrist pin and circlips so you have what’s required for an install. Skirts are treated with a hi-tech molybdenum disulphide (MoS2) coating to promote faster break-in and improved skirt life, and the pistons undergo a T-5 hardening and tempering heat treatment for consistent material properties.
