Wiseco WK1246 Kawasaki Forged Piston Kit Bore - 1100ZXi 2-Stroke 80.00mm

The Wiseco WK1246 is a complete forged piston kit designed for the Kawasaki 1100ZXi and 1100STX personal watercraft, covering model years 1996–2003. Built to Wiseco's exacting standards, this kit delivers the strength and precision required for both recreational use and high-performance applications. The manufacturer part number 809M08000 designates a standard bore diameter of 80.00 mm.

Kit Includes:

• Piston rings
• Wrist pins
• Circlips
• Top end gasket set

Key Features:

• Forged High-Silicon Aluminum Construction: Each piston is forged from a high-silicon, low-expansion aluminum alloy for superior tensile strength, reduced weight, improved heat transfer, and extended service life.
• Waffle-Design Dome: The forged, reinforced dome incorporates a waffle pattern for enhanced heat transfer and additional structural strength under demanding conditions.
• CNC Diamond-Turned Finish: Precision CNC high-speed diamond turning centers hold exact tolerances with no size variation, ensuring consistent fit across all compatible cylinder bore compositions—including cast iron, chrome, Nikasil, and boron composite.
• Closer Wrist Pin Boss Spacing: Tighter wrist pin boss spacing eliminates wrist pin flex, reducing wear and improving power transfer.
• Optimized Strength-to-Weight Ratio: Dedicated forgings and precision lightening operations deliver maximum strength without unnecessary mass.
• Engineered and Machined in the USA: Manufactured at Wiseco's facility in Mentor, OH.

The Wiseco WK1246 is a direct replacement for worn or damaged factory pistons and is an ideal choice for top-end engine rebuilds. Compatible with standard bore cylinders; oversized options may be available for cylinders that have been bored out. Cross-reference: Wiseco piston number 3150KD.
