Prox Piston Kit +0.50mm for 81.50mm Bore 2-Stroke

Elevate your engine's performance with the Prox 81.50mm Piston Kit, engineered for demanding 2-stroke applications. This high-quality replacement kit ensures optimal power delivery and durability, making it an ideal choice for rebuilding or upgrading your 700cc or 1100cc engine.

Description

The Prox 81.50mm Piston Kit is meticulously crafted to meet or exceed OEM specifications, providing a reliable and robust heart for your 2-stroke engine. Each piston is cast from a premium high-silicon-content aluminum alloy, a material renowned for its strength, heat resistance, and lightweight properties. This advanced casting process, combined with precision CNC machining, ensures extremely close tolerances for a perfect fit and consistent performance. The piston features a durable Moly coating on the skirt, which significantly reduces friction and wear, extending the lifespan of both the piston and cylinder wall. Designed as an +0.50 mm oversize piston, this kit is perfect for engines requiring a slight bore increase during a rebuild, restoring lost compression and power. It's suitable for a range of 2-stroke displacements, including 700cc and 1100cc models, offering a standard compression ratio for balanced power and longevity. This comprehensive kit provides everything needed for a seamless installation, including the piston, rings, wrist pin, and circlips, ensuring your engine runs efficiently and powerfully.
