This ring set is aimed at DIY motorcyclists and workshops looking for a suitable replacement part for 55 mm piston/cylinder assemblies. Before installation, check the condition of the cylinder and the radial clearance between piston and cylinder, clean the ring grooves, and adhere to the installation clearances recommended by the manufacturer. Proper installation of the rings is essential to achieve uniform compression and reduce smoke and consumption related to wear.
Notable compatibility: particularly suitable for Vespa PRIMAVERA ET3 (1982‑1983) and Vespa ET3 (1983) in 125 cm³ — verify the piston diameter (Ø55 mm) before ordering to ensure compatibility.
