FULL DESCRIPTION

ProX Piston Kit 54.00 mm Bore for Honda CR125R

This ProX Piston Kit is a high-quality replacement part designed to restore the performance of your motorcycle's engine. Precision-machined using the latest CNC equipment, ProX pistons are crafted from a low-expansion, low-friction alloy, mirroring the materials used by major Japanese engine manufacturers. This makes it an excellent solution for replacing the original piston in your off-road motorcycle.

Key Features:

  • Precision Machining: Manufactured on state-of-the-art CNC equipment for accurate fit and optimal performance.
  • High-Quality Alloy: Utilizes the same low-expansion, low-friction alloy found in original equipment from leading Japanese manufacturers.
  • Performance Coatings: Many ProX pistons feature specialized coatings. The OEM-style Tin coating aids in the break-in process, while a new skirt coating not only assists wear-in but also reduces friction for improved performance. The black coating is formulated from a unique material blend to enhance overall engine performance.
  • Complete Kit: Includes all necessary components for a complete piston replacement.

Replacement Parts Available: ProX Ring Set 02.1225, ProX Piston Pin 04.1547, ProX Clips 05.1510.
