Wiseco Pistons 4382M06700 Forged ATV Piston Kit 67.00mm Oversized 10.25:1 Compression

The Wiseco 4382M06700 is a high-performance forged 4-stroke ATV piston kit designed for 233cc applications requiring a 67.00mm bore size (1.00mm oversize). This complete kit features 10.25:1 compression ratio and is engineered for riders seeking enhanced durability and performance over stock cast pistons.

Key Features:

• Forged 4-stroke piston designed for specific engine applications and built to the tightest tolerances for the ultimate combination of performance and strength
• Forged from aerospace-grade aluminum using a process that compresses the material's molecules, increasing density and aligning grain flow for superior impact and fatigue resistance
• Dedicated forgings allow for optimized strength-to-weight ratio
• Complete kit includes piston, piston rings, wrist pin, and circlips for convenient installation
• Engineered using the latest 3D design techniques and finite element modeling software to ensure highest strength and lightest weight

Kit Includes:

• 1x Forged piston
• 1x Ring Set #2638XD
• 1x Wrist Pin #S259
• 1x Circlip Set #CW16

Wiseco's forged pistons are manufactured in-house at their USA facility, providing superior durability compared to cast pistons. The forging process creates a condensed grain structure aligned to the piston's features, delivering higher mechanical properties and resistance to the extreme demands of high-performance riding. This piston kit is ideal for engine rebuilds, performance upgrades, or replacing worn components in compatible ATV applications.

Important Note: Only Wiseco replacement ring sets can be used on Wiseco pistons. Always measure your cylinder bore and verify clearances before installation to ensure proper fitment.
