Wiseco CK199 Forged Piston Top End Kit Suzuki GSX-R600 1mm Oversize

The Wiseco CK199 is a complete forged piston top end kit designed for the Suzuki GSX-R600, featuring a 1mm oversize bore. Built for performance riders and engine builders looking to restore or upgrade their GSX-R600 powerplant, this kit delivers the precision fitment and durability that Wiseco is known for worldwide.

Key Features:

• Forged high-silicon, low-expansion aluminum construction — delivers superior tensile strength, reduced reciprocating weight, improved heat transfer, and extended service life compared to cast pistons
• CNC diamond-turned finish — precision machined on computer-controlled turning centers for a perfect, consistent finish with zero size variation
• Universal cylinder bore compatibility — pistons are engineered to install confidently in cast iron, chrome, Nikasil, and boron composite cylinder bore compositions
• 1mm oversize specification — ideal for refreshing worn cylinders on the Suzuki GSX-R600, restoring proper bore clearance and compression
• Engineered, forged, and machined in the USA — manufactured at Wiseco's facility in Mentor, OH with over 80 years of piston-making expertise
• Complete kit contents — includes forged pistons, piston rings, wrist pin(s), and circlips; ready to install right out of the box

Wiseco's oversize piston options extend the service life of cast iron lined cylinders. For chrome, Nikasil, or boron composite cylinders, replacement sleeves allow the bore to be re-sleeved to accept oversized pistons like the CK199. Whether you're building for the track or refreshing a street machine, the CK199 provides the reliability and performance the GSX-R600 platform demands.
