The Wiseco 466PS piston rings are made from high-quality materials, ensuring they can withstand the extreme conditions of a high-performance two-stroke engine. The rings are precision-engineered to fit perfectly into the piston, reducing the risk of engine damage due to misalignment or poor fit.
The top ring of the Wiseco 466PS kit is a two-piece design, with a compression ring and an oil control ring. The compression ring is designed to seal the combustion chamber, reducing the loss of compression and improving engine efficiency. The oil control ring, on the other hand, helps manage the oil flow into the crankcase, reducing oil consumption and preventing engine oil from entering the combustion chamber.
The second ring in the kit is the oil scraper ring, which is designed to scrape off any excess oil from the combustion chamber walls and direct it towards the crankcase. This helps maintain proper oil levels in the engine and prevents oil buildup on the piston and cylinder walls.
The third and final ring in the kit is the skirt ring. This ring fits around the bottom of the piston and helps to seal the piston in the cylinder, preventing oil and gas from escaping. The Wiseco 466PS skirt ring is designed to minimize friction between the piston and cylinder walls, reducing engine wear and improving overall performance.
