About this product
Upgrade your motorcycle's engine performance with the high-quality Wossner 250cc 4-Stroke Piston Kit. Engineered for demanding conditions, this Pro Series kit delivers enhanced durability and power for your ride.
Description
Unleash the full potential of your 250cc 4-stroke engine with the Wossner Pro Series Piston Kit. This premium kit is meticulously forged from aerospace-grade aluminum alloy, ensuring exceptional strength and heat resistance under the most extreme operating temperatures and pressures. Designed with a precise 76.01 mm bore size and a high 13.0:1 compression ratio, this piston is engineered to maximize horsepower and torque output, giving you a noticeable edge in performance. The dual ring design provides superior sealing and stability, contributing to consistent power delivery and reduced blow-by.
Every Wossner piston features an advanced Molybdenum Disulphite skirt coating. This permanent, low-friction layer significantly reduces wear, minimizes piston rock, and ensures quieter operation, while also aiding in a smoother, more efficient break-in process. Optimized machining processes result in a lightweight piston without compromising structural integrity, particularly in critical areas like the crown and skirt wall cross-section. This standard size B piston kit (75.97 mm diameter) includes everything you need for a comprehensive replacement: the piston, high-quality nitride-coated steel rings, a durable wrist pin, and secure circlips, making it an ideal choice for enthusiasts and professionals seeking a reliable and performance-driven engine rebuild.
