Wiseco CK191 Forged Piston Kit for Suzuki GSX-R1000 2005-2006

The Wiseco CK191 is a complete forged piston kit designed for the Suzuki GSX-R1000 (2005–2006). Each kit is forged from high-silicon, low-expansion aluminum alloy, delivering superior strength, reduced reciprocating weight, improved heat transfer, and extended service life compared to cast pistons — making it an ideal upgrade for both performance riders and rebuilds.

Key Features:

• Forged Aluminum Construction: High-silicon, low-expansion alloy provides outstanding durability and fatigue resistance under high-RPM and high-temperature conditions
• Diamond-Turned CNC Finish: Each piston is precision-machined on CNC turning centers for a consistent, accurate fit with zero size variation
• Universal Cylinder Compatibility: Engineered for use in cast iron, chrome, Nikasil, and boron composite cylinder bore compositions
• Oversize Availability: Wiseco offers a wide range of oversize options to restore worn cast iron cylinders; chrome, Nikasil, and boron composite cylinders can be re-sleeved to accept oversize pistons
• Complete Kit: Includes piston(s), rings, circlips, and wrist pin (wrist pin included unless otherwise noted)

Wiseco pistons are manufactured in a state-of-the-art computerized facility and are trusted by professional racers and recreational riders worldwide. The CK191 kit provides a straightforward, confidence-inspiring solution for engine rebuilds on the GSX-R1000.
