Wiseco 40319M09600 Forged Piston Kit Bore Powersports - 96.00mm

The Wiseco 40319M09600 is a forged powersports piston kit engineered for high-performance 4-stroke engines with a 96.00mm bore diameter. Manufactured entirely in the USA, Wiseco forges all pistons in-house using premium-grade aluminum alloy, giving this kit a significant strength and durability advantage over standard OEM cast pistons.

Wiseco's proprietary forging process aligns the grain structure of the material to the geometry of the piston, resulting in superior mechanical properties and resistance to impact and fatigue — critical for demanding off-road and performance riding conditions. Built to exacting tolerances, this piston kit delivers quiet operation, consistent ring seal, and extended service life compared to cast alternatives.

Kit Includes:

• Forged aluminum piston (96.00mm bore)
• Piston rings
• Wrist pin
• Wrist pin circlips

Key Features:

• 96.00mm bore diameter — precision-machined to tight tolerances
