Wiseco CK208 Forged Piston Kit Suzuki Hayabusa Turbo - GSX1340R 9.5 1 81mm

The Wiseco CK208 is a complete forged piston kit engineered specifically for turbocharged builds on the Suzuki GSX1340R Hayabusa. Designed with a 9.5:1 compression ratio ideal for forced induction applications, this kit delivers the strength and precision required for high-performance and drag racing use.

Wiseco pistons are produced from aerospace-grade forged aluminum alloy, offering a superior strength-to-weight ratio compared to cast alternatives. The dedicated forgings are tougher and more fatigue-resistant, able to withstand the extreme cylinder pressures generated in turbocharged applications. The dome is engineered for improved flame travel, while the detailed skirt geometry ensures stability and smooth operation throughout the cylinder bore.

Key Features:

• Bore diameter: 81.0mm (standard bore)
• Compression ratio: 9.5:1 — optimized for turbo applications
• Total engine displacement: 1340cc
• Aerospace-grade forged aluminum alloy construction
• Application-specific dome profile for optimized flame travel
• Precision skirt profile for reduced friction and bore stability
• Designed to OEM installed clearance specifications for maximum power, minimal wear, and optimal ring seal at operating temperature
• Includes pistons, wrist pins, and piston rings

Important Installation Note: This piston kit requires the use of a cylinder spacer (Wiseco part number W6342, a 0.032" aluminum spacer plate) for proper fitment on turbo applications. The spacer must be sourced separately.

Whether you are building a dedicated drag bike or a street/strip turbo Hayabusa, the CK208 provides the foundation for a reliable, high-output engine build backed by Wiseco's decades of motorsport forging expertise.
