The ProX 01.2114.B Standard Piston Kit is designed for reliable replacement performance in compatible Yamaha YZ85 two-stroke motorcycles. This Molycoated piston kit is manufactured to work with Nikasil-plated cylinders and provides a direct interchange with the corresponding OEM components, making it a practical choice for engine rebuilding and routine maintenance.
The kit includes the piston, piston rings, wrist pin, and retaining clips needed for installation. Its standard-size 47.45 mm piston configuration is intended for properly prepared, standard-bore applications. The moly coating supports smooth piston operation during break-in and normal engine use, while the included components help simplify the rebuild process compared with sourcing each part separately.
Fitment includes the 2002 through 2011 Yamaha YZ85. Verify the cylinder condition, bore specification, and existing engine components before installation to ensure proper compatibility. The ProX brand is recognized for replacement engine components designed to meet the needs of powersports repair and performance applications.
