The Wiseco 4289PS Piston Kit is designed for Honda ATC/TRX200 models from 1981-1986. This high-performance piston is forged from high-silicon, low-expansion aluminum alloy, ensuring superior strength, reduced weight, and improved heat transfer. The precise CNC-machined finish guarantees a perfect fit with minimal size variation, making it compatible with various cylinder bore compositions. This 4-stroke piston kit includes a piston, rings, wrist pin, and circlips. It features a dedicated lightweight forging for enhanced durability, and a race-ready dome design for improved combustion flow. The armor glide skirt coating reduces friction in racing applications. Oversized pistons may require cylinder sleeving. Wiseco's advanced engineering, including anti-detonation grooves and optimized ring land diameter, helps eliminate ring blow-by while maximizing engine performance. This piston is designed to provide increased power, torque, and throttle response, making it an excellent choice for both racing and recreational use.
