Honda Pioneer Forged Replica Piston Kit - Vertex Pistons - +0.50mm Oversized - `15-`23. A direct-fit forged replica piston kit designed for Honda Pioneer 500 (2015–2023) 500cc applications, supplied complete with rings, wrist pins and circlips for a straightforward rebuild or performance refresh.

This Vertex kit is engineered to match cylinder bore specifications with Exact Fit A, B or C pistons to minimize blow-by and reduce oil consumption. Each piston is heat treated with a T-5 hardening and tempering cycle for consistent strength and durability, and the skirts receive a molybdenum disulphide (MoS2) coating to promote faster break-in and longer piston life. Kits include everything required for installation so you can replace pistons without sourcing additional parts.
