( Brand: Namura Technologies ), ( Manufacturer Part Number: NW-20000R ), ( Part Type: Ring Piston )
The Namura NW-20000R piston rings are specifically designed to fit Kawasaki JS300 SX Standard motorcycles manufactured between 1986 and 1991 with a cylinder bore size of 76mm. These piston rings are an essential component of the engine, sealing the gap between the piston and the cylinder wall to contain the combustion pressure and prevent the loss of engine oil.
The Namura NW-20000R piston rings are manufactured using the latest technology and high-quality materials. The compressive ring strength has been optimized to ensure proper sealing at the top of the piston, while the ring width and collar design provide excellent compression and oil control. The rings are also heat treated for improved durability and resistance to wear, ensuring long-lasting performance.
The top ring in this set is a compression ring and is designed to provide efficient combustion and prevent oil leakage. The second ring is the oil control ring, which helps maintain correct engine oil levels by controlling oil consumption and preventing excessive oil consumption. The third ring is the oil scraper ring, which ensures the engine stays clean by scraping off excess oil from the cylinder wall and directing it back to the crankcase for reuse.
These piston rings are precision manufactured and come in sets, ensuring perfect fitment and ideal matching between rocker arm rings, second rings, and oil control rings. The rings are shipped in a protective packaging to prevent any damage during transportation.
By installing Namura NW-20000R piston rings on your Kawasaki JS300 SX Standard motorcycle, you can expect improved engine performance, better fuel efficiency, and extended engine life. The rings come with a 100% satisfaction guarantee, ensuring you get the best value for your money. For professional installation, it is recommended to consult with a certified mechanic.
