Description

The Wossner Standard Series Piston Kit is meticulously crafted to deliver unparalleled performance and longevity for your 250cc 4-stroke engine. Each piston is precision-forged from high-grade aerospace aluminum alloy, ensuring exceptional strength while maintaining optimal lightness through advanced machining. This meticulous design strengthens crucial areas like the crown and skirt wall cross-section, providing robust durability under extreme conditions. With a high 14.1:1 compression ratio and a 77.97 mm piston diameter, this kit is engineered to unlock your engine's full potential, offering a noticeable boost in power and responsiveness. The piston skirts feature a permanent Molybdenum Disulphite (Moly) coating, drastically reducing friction and piston rock, which translates to quieter operation, improved engine efficiency, and a smoother break-in process. The dual ring design, complemented by nitride-coated, steel, and cast rings, ensures superior sealing and wear resistance, making this Wossner 250cc 4-stroke piston kit an essential component for any serious engine rebuild or performance upgrade.
