Prox Cast Replica 2-Stroke Piston Kit

Elevate your motorcycle's engine performance and reliability with the Prox 2-stroke cast piston kit. Engineered to meet or exceed OEM specifications, this kit provides a durable and high-performing replacement for your worn-out piston, ensuring your ride maintains optimal power and efficiency.

Description

The Prox cast replica 2-stroke piston kit is meticulously designed for exceptional stability and longevity in demanding motorcycle engines. Crafted through a gravity casting process, this 53.98 mm piston is made from a high-quality aluminum alloy containing approximately 18% silicon. This significant silicon content is crucial for reducing thermal expansion, which helps maintain consistent piston-to-bore clearance across a wide range of operating temperatures. The result is a more stable engine, reduced wear, and prolonged component life. While often mirroring OEM configurations, Prox engineers frequently optimize these designs to unlock opportunities for increased performance. This piston kit is versatile, manufactured for compatibility with both traditional cast iron cylinder bores and modern Nikasil-plated cylinders. For Nikasil applications, Prox offers a range of precise oversizes (graded A/B/C/D), each increasing the piston diameter by 0.01mm, allowing for exact fitment during rebuilds. The piston also features a moly-coated skirt, further enhancing durability by minimizing friction and wear.

Features & Highlights

• Enhanced Durability & Stability: Gravity cast from a premium aluminum alloy with approximately 18% silicon, ensuring exceptional stability and long-lasting performance under extreme 2-stroke engine conditions.
• Optimized Thermal Management: High silicon content actively reduces thermal expansion, maintaining optimal piston-to-bore clearance for consistent power delivery and extended engine life.
• Precision OEM-Style Design: Engineered to replicate or improve upon OEM specifications, providing reliable fitment and often enhanced performance over stock components for your motorcycle.
