This piston has the same characteristics as the original but is improved. With its flat piston head, its slightly bevelled ring (watch out for the direction), its graphite coating and its lubrication point on the exhaust bar, it offers increased reliability and optimum performance. Sold as shown, with piston, ring, 2 clips and piston pin. We advise you to change your needle cage every time you change a piston, to avoid premature breakage.
