Wossner Forged Piston Kit - 73mm Bore - 250cc - Size A - 8646DA

Elevate your motorcycle's performance with the Wossner Standard Series Piston Kit, meticulously engineered for 250cc 4-stroke engines. This premium Wossner 250cc 4-stroke piston kit delivers exceptional durability and power, ensuring your engine runs smoother and stronger.

Description

The Wossner Standard Series Piston Kit is designed to meet the rigorous demands of high-performance motorcycle engines. Forged from aerospace-grade aluminum alloy, this piston provides superior strength and resilience while maintaining an optimized lightweight design. The crown and skirt wall cross-sections are precisely machined to reduce reciprocating mass without compromising structural integrity, leading to improved throttle response and higher RPM capabilities. A key feature is the advanced Molybdenum Disulphite (Moly) skirt coating, which significantly reduces friction between the piston and cylinder wall. This coating not only contributes to quieter operation by minimizing piston rock but also aids in the crucial engine break-in process, extending the life of your engine. With a bore size of 73.00 mm and a precise 72.95 mm piston diameter, coupled with a robust 10.2:1 compression ratio, this kit is perfectly suited for enhancing the power output and reliability of your 250cc 4-stroke motorcycle engine.
