( Brand: Namura Technologies ), ( Manufacturer Part Number: NX-10200-4R ), ( Part Type: Ring Piston )
The Namura NX-10200-4R 040 piston rings are specifically designed for the two-stroke, 2-valve Honda XR200 and Honda XR200R motorcycles manufactured between the years 1980 and 2002. This set of piston rings comprises four rings: an compression ring, an oil control ring, a combustion ring, and a scraper ring. These rings are engineered to deliver exceptional performance, durability, and reliability for your Honda XR200 or Honda XR200R engine.
The compression ring, the innermost ring in the set, is responsible for creating the necessary grip between the piston and the cylinder wall to ensure optimal compression of the fuel-air mixture during the combustion process. The advanced design of this compression ring ensures efficient sealing and reduced heat transfer, improving overall engine efficiency.
The oil control ring sits just below the compression ring. Its primary function is to prevent oil from escaping from the crankcase into the combustion chamber. This oil control ring is meticulously engineered to maintain a consistent oil film on the cylinder walls, reducing engine wear and ensuring long engine life.
The combustion ring is essential for efficient fuel burning during the combustion process. This ring is installed slightly further out from the compression ring and is designed to seal effectively against the cylinder wall, ensuring a proper gas flow during combustion for optimal engine performance.
Lastly, the scraper ring, located at the outermost position of the piston ring set, is crucial for transferring excess heat away from the piston and into the engine coolant. This ring incorporates grooves that efficiently scrape off excess heat generated during the combustion process, keeping your engine running at optimal temperatures and delivering a more enjoyable and consistent riding experience.
These high-quality piston rings from Namura are designed to provide you with a reliable replacement solution for your Honda XR200 or Honda XR200R motorcycle engine. Enhancing performance, longevity, and efficiency, these rings are the ideal choice for motorcycle enthusiasts seeking top-tier replacement parts for their beloved two-stroke Honda motorcycles.
