About this product
Upgrade your two-stroke engine with the Prox Cast Piston Kit. Designed for superior stability and performance, this piston kit is engineered to meet or exceed OEM specifications, offering a reliable and cost-effective solution for your motorcycle.
Description
The Prox Cast Piston Kit utilizes gravity casting with a high-silicon aluminum alloy, containing approximately 18% silicon, which significantly reduces thermal expansion. This ensures consistent performance under demanding conditions. Specifically designed for two-stroke engines, these pistons are compatible with both cast iron and Nikasil cylinder bores. For Nikasil cylinders, ProX provides a range of oversizes (A/B/C/D) increasing in increments of 0.01mm, ensuring a precise fit. Easy to install, the Prox piston enhances engine efficiency and extends its lifespan. Count on Prox for quality and durability.
