PISTON KIT 2021-24 KTM 150 EXC TPI, PROX 01.6241.C
ProX pistons are precision machined on CNC equipment using the same low-expansion, low-friction piston alloy utilized by major Japanese engine manufacturers. This ProX Piston Kit is a high-quality replacement for the original piston. Many ProX pistons feature a Tin coated assist for the wear-in process and a new skirt coating that reduces friction after wear-in, contributing to increased performance. ProX offers pistons in standard size and oversizes (A, B, C, D+) for Nicasil/plated cylinders. Size 57.96mm.

FULL DESCRIPTION
ProX Piston Kit 57.96mm
This ProX Piston Kit is engineered for high performance and durability, serving as a premium replacement for original pistons in motorcycles and other powersports vehicles. Precision machined using state-of-the-art CNC equipment, this kit utilizes a low-expansion, low-friction piston alloy consistent with that used by major Japanese engine manufacturers.
The piston features a unique black skirt coating. This advanced coating is a carefully developed blend of materials designed to not only facilitate the crucial wear-in process but also significantly reduce friction once the engine is broken in, leading to enhanced performance.
For modern engines with Nicasil plated cylinders, ProX offers a comprehensive range of pistons. This specific kit is available in standard size, with additional oversizes (A, B, C, D) also offered to accommodate cylinder wear or re-boring.
