Wiseco K0076X2 Piston Kit Oversize Forged - 0.020 2-Stroke

The Wiseco K0076X2 is a forged oversize piston kit engineered for two-stroke powersports engines. As part of Wiseco's trusted performance piston line, this kit features a +0.020" (0.5mm) overbore sizing — ideal for engine rebuilds requiring a fresh bore job to restore proper cylinder clearances.

Wiseco pistons are cold-forged from 4032 aluminum alloy, offering superior strength-to-weight ratio compared to cast alternatives. The forging process aligns the grain structure of the aluminum, resulting in a piston that withstands higher heat cycles and mechanical stress — critical for high-revving two-stroke applications.

Key Features:

• Forged 4032 aluminum construction for high strength and thermal stability
• +0.020" oversize bore designation for use with a freshly bored cylinder
• Precision CNC machined to tight tolerances for optimal ring seal and performance
• Hard anodized crown for improved heat resistance and wear protection
• Includes piston, wrist pin, circlips, and piston rings as a complete kit
• Manufactured in the USA to OEM and performance specifications

Wiseco has been a leading manufacturer of forged pistons for motorsports, powersports, and racing applications for decades. The K0076X2 is a direct replacement piston kit designed for a reliable, performance-oriented engine rebuild.
