Wiseco Piston Kit – 50mm Bore – +2.0mm – 520M05000

Upgrade your two-stroke engine’s performance and reliability with the Wiseco PE Piston Kit 2.0mm Oversize, engineered specifically for the Yamaha YZ 80 and YZ 80 LW models from 1985-1999. This high-performance piston kit is meticulously crafted to deliver increased horsepower and exceptional durability, making it ideal for both competitive racing and demanding trail applications.

Description

The Wiseco PE Piston Kit is forged from premium high-silicon aluminum alloy, ensuring maximum strength and dependability under the most extreme conditions. Its innovative forging design and piston skirt geometry are engineered to optimize the combustion process, unlocking maximum horsepower and torque from your Yamaha YZ 80 engine. Each kit comes complete with a forged piston, high-quality rings, a precision-machined wrist pin, and durable circlips, providing all the essential components for a comprehensive top-end rebuild.

These high-tech pistons feature designs that achieve maximum compression ratios, supported by ultra-stiff strutted forgings for superior stability. The included titanium nitride-coated rings significantly reduce friction and wear, contributing to sustained power output over longer service intervals. Furthermore, every piston is E-Coated on the crown, ring grooves, and pin bore, offering unparalleled wear resistance and protection against micro-welding, galling, and detonation. As part of Wiseco’s GP Series, this piston features less external machining to enhance bore sealing for increased compression, and boost ports are removed to ensure a more predictable powerband and an impressive pull on the top end.
