Kawasaki KX 250 Piston Kit - Vertex Pistons - Cast Replica - `02-`04. A direct-replacement piston kit designed for 2002–2004 KX250 models, offering a reliable, factory-style option for riders restoring or tuning their two-stroke engine.

This Vertex cast replica kit is built to match your cylinder bore with A, B, or C piston sizes to minimize blow-by and reduce oil consumption while maintaining performance. Each kit includes the piston, rings, wrist pin and circlips required for installation. Skirts are treated with a hi‑tech molybdenum disulfide (MoS2) coating to promote faster break‑in and extend piston life, and pistons are heat treated using a T‑5 hardening and tempering cycle for consistent durability.
