Wiseco CK227 Forged Piston Kit 84mm 13.5:1 Kawasaki ZX-14 4-Stroke Top End

The Wiseco CK227 is a complete forged top-end piston kit engineered for the Kawasaki Ninja ZX-14 platform, featuring an 84.00mm standard bore, 13.5:1 compression ratio, and a total displacement of 1352cc. Designed for high-performance street riding and demanding powersports use, this kit delivers the strength and precision needed for a reliable, power-optimized engine rebuild.

Key Features:

• Aerospace-Grade Forged Construction: Pistons are forged from high-silicon, low-expansion aluminum alloy, providing superior strength-to-weight ratio, improved heat transfer, and extended service life compared to OEM cast pistons.
• ArmorGlide® Skirt Coating: Proprietary skirt coating reduces piston-to-wall friction and noise, contributing to measurable horsepower gains and smoother operation.
• CNC Diamond-Turned Finish: Each piston is machined on precision CNC turning centers for a perfect finish with zero size variation, ensuring consistent bore clearance across all cylinder bore compositions — including cast iron, chrome, Nikasil, and boron composite.
• Floating Wrist Pin Design: Features a floating-style wrist pin for reduced stress on the pin boss and smoother power transfer at high RPM.
• Performance Ring Set: Includes a gas-nitrided steel top ring and chrome-faced stainless steel oil ring for excellent sealing, reduced blowby, and long ring life.
• Oversize Availability: Wiseco's oversize piston range supports cylinder resleeving of chrome, Nikasil, and boron composite bores, extending cylinder life through multiple rebuilds.
• Complete Kit: Includes forged pistons, ring sets, floating wrist pins, and wrist pin retainer circlips — everything needed for a full top-end rebuild.

The Wiseco CK227 is manufactured in the USA and backed by Wiseco's reputation for quality in motorsports applications ranging from street performance to competitive road racing. This kit is sold as a complete set and does not include head gaskets.
