The WiseCO MN/3477 piston kit is a high-performance replacement option for the pistons on the 1985-1986 Honda ATC250R engine. This piston kit is designed to provide improved durability and power output compared to the OEM pistons.

Each piston in this kit is forged from a high-strength alloy, ensuring superior strength and resistance to engine stress. The piston crown is optimized for a better combustion process, providing increased horsepower and torque.

The piston rings included in this kit are made of a high-temperature, low-friction material. This ensures a tight seal between the piston and cylinder wall, reducing blow-by and improving engine efficiency. The piston rings are also designed to provide excellent wear resistance, ensuring that they last longer than OEM rings.

The piston pins are also upgraded in this kit. They are made from a high-strength alloy and are chrome-molybdenum coated, reducing the risk of galling and ensuring a long-lasting, smooth piston-pin connection.

The piston kit also includes wrist pins, piston pin bushings, and piston pin clips. The wrist pins are made from high-strength alloy, and the piston pin bushings are made of a high-performance material that provides excellent durability and reduces friction.

This piston kit is a direct replacement for the OEM pistons and comes with all necessary hardware for installation.
