This high-quality piston kit delivers enhanced power and durability, making it an ideal choice for enthusiasts and professionals seeking a robust engine upgrade or rebuild.
Description
The Wossner Premium Series Piston Kit is meticulously crafted from aerospace-grade forged aluminum alloy, ensuring exceptional strength and lightweight performance for your 500cc 4-stroke engine. Designed with a precise 94.94 mm piston diameter and a 95.00 mm bore size, this standard size A piston maintains an aggressive 12.75:1 compression ratio, optimizing power output and responsiveness.
