Why Forged?

Unlike cast pistons, Wiseco forgings feature a condensed, aligned grain structure that produces superior mechanical properties, higher resistance to impact and fatigue, and the ability to withstand extreme operating conditions without catastrophic failure. The optimized strength-to-weight ratio ensures maximum performance without unnecessary mass.

Key Features:

• 65.00 mm bore — standard size fitment
• 10.25:1 compression ratio for strong power delivery
• Forged aluminum construction for improved tensile strength and service life
• Dedicated forging design optimizes strength-to-weight ratio
• Engineered, forged, and machined in the USA (Mentor, OH)
• Built to tight tolerances for each specific engine application
• Kit includes high-quality piston rings, wrist pin(s), and circlips

Wiseco remains the only U.S. manufacturer with full in-house forging capabilities, ensuring complete quality control from raw material to finished part. The 4394M06500 is the trusted choice for riders rebuilding or upgrading Honda 200cc engines to perform at their best.
