The oil control ring is designed to minimize oil consumption and ensure consistent oil control.

This piston kit is a direct replacement for the OEM piston and ring set and is easy to install. It is recommended for riders who are looking to increase the power output and reliability of their Suzuki RM125 or RM125L motorcycle. With its superior materials, precise engineering, and proven performance, the WiseCO 580P4 0.40 Pro Forged Piston Kit is an excellent investment for any Suzuki RM125 or RM125L rider.
