Review PRO X Prox Piston Kit .050 Oversize fits CR250R

The PRO 0399 FT84-FT85 CR250R Piston 0.50 Kit is a high-performance upgrade designed specifically for the CR250R motocross bike. This piston kit represents an excellent investment for riders looking to enhance the power output and overall engine performance of their bike.

The piston is crafted from forged aluminum alloy, ensuring superior strength and durability. Its design features a compression height of 0.50 inches, making it suitable for advanced riders seeking increased horsepower and torque. The piston's ring package includes a compression ring, a transfer port ring, and an oil control ring that work together to optimize engine efficiency and reduce friction.

The piston kit also includes a rings kit, consisting of a compression ring, a transfer port ring, and an oil control ring. These rings have been engineered to be narrow in design, allowing for minimal friction and better sealing against the cylinder wall. The rings are made of top-quality materials, which provide excellent wear resistance and long-lasting performance.

The skirt design of the piston is optimized for better engine breathing and cooling. The piston and piston pin are finished with a durable coating that resists scuffing and wear, enabling the piston to run smoothly and reliably for an extended period.

Compared to OEM pistons, the PRO 0399 FT84-FT85 CR250R Piston 0.50 Kit delivers increased performance, longer engine life, and greater reliability.
