This design helps to reduce engine oil consumption, improve engine performance, and extend the life of the engine.

The two skirt rings, also known as the third and fourth rings, are responsible for sealing the piston to the cylinder wall. They feature a high-tensile, heat-resistant material that offers excellent sealing capabilities even under high cylinder pressures and temperatures. These rings are also designed to minimize friction and wear, ensuring long-lasting performance and reliability.

The MN/KW51 ring set is precision-manufactured to meet or exceed OEM specifications, ensuring a perfect fit and function in your 2008-2009 Honda CRF230L engine. It is also backed by a comprehensive warranty, providing peace of mind and protection against any manufacturing defects.
