Description
Piston rings are critical wear items that directly impact compression, power delivery, and oil control in your two-stroke engine. Over time, rings wear and lose their seal, causing loss of compression, increased blow-by, and excessive oil consumption. A fresh Wiseco ring set restores your engine’s efficiency and extends service life between rebuilds.
The Wiseco 2165CD is precision-engineered specifically for 55mm bore applications found in 1985-1986 Honda CR125R and Suzuki RM125 engines. This ring set features proven metallurgy designed to handle the thermal and mechanical demands of high-RPM two-stroke operation while maintaining a tight seal against cylinder walls.
