About this product
About this product
The Prox Piston Kit provides a high-quality, reliable solution for your engine rebuild. Manufactured with precision and using advanced materials, this kit ensures optimal performance and longevity.
Description
This Prox Piston Kit is engineered for superior strength and durability. The piston is cast from a hypereutectic alloy, which provides exceptional strength while minimizing expansion. Its special dual-ring setup enhances durability and wear resistance, crucial for demanding applications. The full MOS2 skirt coating reduces friction and scuffing, particularly during the break-in period, while the anodized piston dome offers increased protection against excessive heat. High-quality rings, like Riken, are included for optimum heat transfer and sealing, ensuring efficient combustion and power delivery. Designed for 544cc 2-stroke engines with a 73.50mm bore size, this piston kit delivers consistent performance and reliability.
