VERTEX Piston (manufacturer reference 23702B) — designed for engine refurbishment of off-road machines, this VERTEX piston is aimed at motocross riders and preparers looking for an original part to replace a worn component. VERTEX is renowned for its thermal components intended for off-road use and equips many brands as original equipment.
This aluminum piston is delivered in oversize +0.01 (letter B): a classic choice for light cylinder reboring. Intended for replacement, it adheres to the specified dimensions for precise fitting with appropriate rings and wear control. Its machining and tolerances are designed for the typical stresses of motocross bikes (sharp accelerations, high revs, and muddy conditions).
Main compatibilities: HONDA CRF 250 R (ME10) — 2015 / 2016 / 2017 (250 cc). Before installation, check the bore dimensions, the condition of the cylinder, and follow the engine's break-in recommendations to ensure optimal performance.
