Wiseco CK150 Big Bore Forged Piston Kit Suzuki - 76mm 13.5 1 GSXR1000

The Wiseco CK150 is a complete top-end forged piston kit engineered for the Suzuki GSX-R1000 (2001–2004). Featuring a 76.00mm bore (+3mm over stock) and a high-compression 13.5:1 ratio, this kit bumps total displacement to 1071cc and is purpose-built for serious street and drag racing applications. A head gasket is included to complete the rebuild.

Key Features:

• Forged aerospace-grade aluminum construction — Wiseco's forging process compresses material molecules for increased density, superior strength, and fatigue resistance compared to cast pistons
• 76.00mm bore / 13.5:1 compression ratio — Delivers a significant displacement and compression increase over the stock 999cc engine
• ArmorGlide skirt coating — A permanently applied dry-film lubricant that reduces piston-to-wall friction, lowers operating noise, and improves seizure resistance, especially during cold starts
• Race-ready dome finish — Smooth dome edges promote improved combustion flow for maximum power output
• Dedicated forging per application — Each piston is engineered specifically for the GSXR1000 bore geometry for optimal piston-to-wall clearance
• High-performance ring kit included — Matched ring set designed for compatibility with the Wiseco piston
• Alloy wrist pin included — Lightweight, high-strength pin engineered to handle increased cylinder pressures
• Circlips included — Complete hardware for a full top-end assembly

The Wiseco CK150 kit cross-references piston part number 4819M and ring set 2992XG. This kit is ideal for performance builds targeting increased displacement and compression in drag racing or high-output street applications. Note: This product is not CARB legal and is not for sale in California.
