VERTEX offers you this replacement piston for your original top motor mounted on your Gas Gas, TM, Rieju MR 250cc motocross bike. This piston has the same characteristics as the original, but is improved and forged. With its flat piston head, its slightly bevelled ring (be careful of the direction), its graphite coating and its lubrication point on the exhaust bar, it offers increased reliability and optimum performance. Sold as shown in the photo, with piston, ring, 2 C-clips and piston pin. We advise you to change your needle cage every time you change a piston, to avoid premature breakage.
