Wiseco 235M05350 2-Stroke Forged Piston Kit 53.50mm Bore

The Wiseco 235M05350 is a high-performance forged 2-stroke piston kit featuring a 53.50mm bore, engineered specifically for small-displacement Yamaha 2-stroke engines. Forged from high-silicon aluminum alloy, this piston kit delivers superior strength, reduced weight, and improved heat transfer compared to standard cast pistons.

Key Features:

• Forged from high-silicon, low-expansion aluminum alloy for maximum strength and dependability
• Dedicated forging design optimizes strength-to-weight ratio using aerospace-grade alloy
• Innovative forging profile and piston skirt geometry engineered to maximize horsepower and torque
• Designed and built for each specific 2-stroke powersports engine application
• Improved tensile strength over cast pistons for extended service life under high-performance conditions
• Engineered, forged, and machined in the USA in Mentor, OH
• Compatible with cast iron, chrome, Nikasil, and boron composite cylinder bore compositions

Kit Includes:

• Forged piston
• High-quality piston ring(s)
• Wrist pin(s)
• Circlips

Important Notes:

• This is an oversize piston at 53.50mm bore — cylinder boring or sleeving is required prior to installation
