Review PROX Piston Ring Set 66.50mm fits 250 1980–1987

Introducing the 02.2020.250 piston ring set for the Yamaha YPVS RD350LC engine, specifically designed for engines with a piston diameter of 66.50mm and a stroke length between 80-87mm. This comprehensive ring set includes all the necessary components to ensure optimal engine performance.

The set includes six piston rings in total: an oil control ring, two compression rings, one oil scraper ring, and two piston rings for the top and bottom of the engine respectively. Each ring is meticulously crafted using high-quality materials to provide exceptional durability and reliability.

The oil control ring is designed to maintain proper oil pressure within the engine by preventing oil from escaping between the piston and cylinder walls. Its unique design ensures effective sealing, reducing oil consumption and preventing blowby.

The two compression rings work together to compress the air-fuel mixture during the combustion process. These rings are made of a high-temperature alloy that ensures they can withstand the intense heat and pressure inside the engine. Their precise fit ensures a tight seal, improving combustion efficiency and engine power.

The oil scraper ring is responsible for scraping excess oil from the piston skirt and returning it to the crankcase for reuse. Its design ensures efficient oil circulation, reducing oil consumption and preventing engine wear.

The top and bottom piston rings are specifically designed for their respective positions within the engine. The top piston ring is responsible for sealing the combustion chamber, preventing the escape of gases during the power stroke. The bottom piston ring seals the crankcase, preventing the loss of oil and ensuring proper lubrication of the engine.

This piston ring set is a must-have for any Yamaha YPVS RD350LC owner looking to maintain their engine's performance and longevity. Each ring is carefully manufactured to meet the highest standards of quality and precision, ensuring a perfect fit and optimal engine operation. With this ring set, you can enjoy the power and reliability of your Yamaha motorcycle for years to come.
