High-Performance 4-Stroke Racing Cylinder Kit

This high-performance 4-stroke racing cylinder kit is engineered for maximum durability, power output, and reliability under extreme racing conditions.

The cylinder is manufactured from premium cast iron and reinforced with AISI 4140 steel, featuring a precision nitriding treatment to significantly enhance surface hardness, wear resistance, and thermal stability. With a 68 mm bore, the cylinder is optimized for increased displacement and improved combustion efficiency.

The kit includes a forged aluminum piston, specifically designed for high-compression applications. The forged construction ensures superior strength, reduced weight, and excellent resistance to high temperatures and mechanical stress, making it ideal for competitive racing environments.

Sealing performance is ensured by a head gasket  copper treatment, providing exceptional resistance to pressure and heat while maintaining optimal compression and long-term reliability.

Designed as a complete racing solution, this cylinder kit delivers consistent performance, improved throttle response, and extended service life for demanding 4-stroke racing applications.
