Wossner Standard Series Piston Kit for 250cc 4-Stroke

Upgrade your engine's performance and reliability with the Wossner Standard Series Piston Kit for 250cc 4-Stroke engines. Engineered for the demanding conditions of high-performance motorcycles, this kit delivers exceptional strength, reduced friction, and a complete solution for your rebuild or upgrade needs.

Description

The Wossner Standard Series Piston Kit is meticulously designed to elevate the performance of your 250cc 4-stroke engine. Forged from aerospace-grade aluminum alloy, this Wossner forged piston ensures superior durability and resistance to extreme temperatures and pressures, making it a robust motorcycle engine piston choice. Each piston features an advanced Molybdenum Disulphite (Moly) skirt coating. This permanent coating significantly reduces friction and piston rock, leading to quieter operation, improved power delivery, and an extended lifespan for your engine components. The optimized machining process focuses on achieving the lightest possible weight without compromising strength in critical areas such as the crown and skirt wall cross-sections.

With a precise piston diameter of 77.97 mm and a high 14.0:1 compression ratio, this high-performance piston kit is engineered for optimal power output. The dual ring piston design, utilizing nitride-coated steel and cast rings, provides excellent sealing and wear characteristics. This comprehensive kit includes everything you need for a seamless installation: the piston, piston rings, wrist pin, and retaining clips, ensuring a complete and ready-to-install solution for your engine rebuild. Experience the Wossner difference with a piston kit built for peak performance and enduring quality.
