VERTEX Forged Piston (manufacturer ref. 24268A): a forged aluminium piston designed for demanding motocross engines. Precisely designed and machined by VERTEX, it features an oversize letter A and a piston diameter of Ø 76.95 mm for a nominal bore of 77.00 mm. Its geometry and forged manufacturing ensure an optimised microstructure, better mechanical resistance, and fatigue performance compared to cast parts.
This piston is aimed at motocross riders seeking a reliable engine part for the rebuilding or preparation of a cylinder. Forging improves resistance to thermomechanical stresses and facilitates heat management during intensive use. Fitting and bore control are recommended before installation to ensure correct ring clearance and tolerances.
Main compatibilities: KAWASAKI KX 250 (KX252A) 2019 and KAWASAKI KX 250 F (KX252A) 2018 — for engine capacities of 250 cm³. Please check the reference and engine specifications before purchase.
