Wiseco 4583M06700 Forged Piston Kit Bore CR Kawasaki - 67mm 11.8 1 ZX600

The Wiseco 4583M06700 is a high-performance forged 4-stroke piston kit designed specifically for the Kawasaki ZX600 Ninja ZX-6R engine. Featuring a 67.00mm bore and an 11.8:1 compression ratio, this piston kit is precision-engineered to deliver maximum power output and long-term reliability for street and track applications.

Key Features:

• 67.00mm bore diameter — +1mm oversize; requires cylinder boring or sleeving
• 11.8:1 compression ratio for increased performance over stock
• Forged from high-silicon, low-expansion aluminum alloy for superior strength, reduced weight, and improved heat transfer
• Dedicated forging design optimizes strength-to-weight ratio for each specific engine application
• Built to tight tolerances for consistent fitment and maximum sealing
• Engineered, forged, and machined in the USA in Mentor, OH
• Kit includes piston, rings, wrist pin, and circlips

Wiseco forged pistons offer superior durability compared to cast alternatives. Forged construction produces a condensed grain structure aligned to the part geometry, resulting in higher mechanical properties and resistance to impact and fatigue — critical for high-performance powersports engines.

Note: This is an individual (single) piston kit. For a complete four-cylinder engine rebuild, four kits are required. As an oversize piston, cylinder boring or sleeving is required before installation.
