Wossner Standard Series Piston Kit

Elevate your motorcycle's engine performance with the Wossner Standard Series Piston Kit. Engineered for superior durability and efficiency, this premium 4-stroke piston kit is designed to deliver reliable power and extended engine life, making it an ideal choice for enthusiasts and professionals seeking an upgrade or rebuild.

Description

The Wossner Standard Series Piston Kit is meticulously crafted to meet the demanding requirements of high-performance motorcycle engines. Forged from aerospace-grade aluminum alloy, this piston ensures exceptional strength and resilience under extreme operating conditions. A critical feature is the permanent Molybdenum Disulphite (Moly) skirt coating, which significantly reduces friction, minimizes piston rock, and promotes quieter engine operation. This advanced coating also aids in the break-in process, contributing to improved performance and longevity.

Optimized machining techniques ensure the piston achieves an ideal balance of lightness and structural integrity. Key areas such as the crown and skirt wall cross-section maintain robust strength, preventing premature wear and failure. Designed for 4-stroke engines, this kit boasts a high 14.1:1 compression ratio, translating to enhanced power delivery and responsiveness. With a precise 77.97 mm piston diameter and a 52.20 mm stroke length, the Wossner Piston Kit provides a precise fit for standard bore applications. Each comprehensive kit includes the piston, high-quality nitride coated steel and cast rings, a sturdy piston pin, and reliable clips, providing everything needed for a complete and confident engine rebuild.
