Introducing the Suzuki 12140-40700 piston ring set for the RM250 motorcycle model years 1976-78. This ring set is an essential component for maintaining the optimal performance and longevity of your two-stroke engine.

The Suzuki 12140-40700 piston ring set includes four rings: the compression ring, the oil control ring, the scraper ring, and the piston ring carrier. Each ring is meticulously crafted from high-quality materials to ensure a perfect seal and efficient engine operation.

The compression ring, responsible for compressing the fuel-air mixture during the combustion process, is made of a durable, heat-resistant material. Its precise cross-section design ensures maximum sealing performance and efficient power transfer.

The oil control ring, designed to prevent oil from leaking into the crankcase, is manufactured from a flexible, oil-resistant material. Its optimized width and thickness provide an effective seal while allowing for proper engine lubrication.

The scraper ring, also known as the skirt ring, is tasked with removing excess carbon build-up from the piston. Made of a wear-resistant material, it effectively scrapes away carbon deposits, ensuring continued engine efficiency.

The piston ring carrier is a critical component that holds the piston rings in place. Its robust design ensures a secure fit and proper alignment of the rings for optimal engine performance.

The Suzuki 12140-40700 piston ring set is an excellent choice for RM250 motorcycle owners seeking to restore their engine's performance or maintain it at its best. These rings are specifically designed to fit and function optimally in the RM250 motorcycle engine during the specified model years.
