Prox Cast Piston Kit for 2-Stroke Engines

Elevate your motorcycle's performance and reliability with the Prox 2-stroke cast piston kit, meticulously engineered for optimal engine function. This high-quality piston kit provides a durable and stable foundation for your two-stroke engine rebuild or upgrade.

Description

The Prox 2-stroke cast piston kit is designed to meet or exceed OEM specifications, with ProX engineers often refining designs for enhanced performance. Each Prox cast piston kit, including the 53.96 mm standard size B, is crafted through a precise gravity casting process utilizing a specialized aluminum alloy. A crucial element in its composition is the approximately 18 percent silicon content, which significantly contributes to decreased thermal expansion. This ensures exceptional stability and consistent performance even under extreme operating temperatures, making it a robust choice for any motorcycle piston kit replacement. These pistons are versatile, manufactured to be compatible with both traditional cast iron cylinder bores and modern Nikasil cylinder bores. For Nikasil applications, ProX offers a range of oversizes, graded in A/B/C/D, with each step increasing the diameter by 0.01mm, ensuring a perfect fit for various rebuild scenarios. The piston also features a durable moly-coated skirt, further reducing friction and extending engine life.
