The Wiseco CK222 is a complete forged top-end piston kit engineered specifically for the Honda CBR600RR. Built to a 67.00mm bore and 13.5:1 compression ratio, this kit delivers the precision fitment and high-performance durability that demanding street and track riders require. Total displacement with this kit is 599cc.

Key Features:

• Aerospace-grade forged aluminum construction — Wiseco is the only U.S. aftermarket piston manufacturer that uses exclusively the forging process, compressing the alloy's molecular structure for superior density, impact resistance, and fatigue strength compared to cast alternatives
• Dedicated forgings for an optimized strength-to-weight ratio, with a dome profile engineered for improved flame travel and combustion efficiency
• ArmorGlide® skirt coating reduces friction and noise at the cylinder wall, contributing to increased horsepower and extended service life
• Precision-machined skirt shape and profiles for stability and smooth operation throughout the full range of cylinder bore movement
• Horizontal slot-pin oiling reduces friction and provides scuff resistance, complemented by a pressure seal groove for maximum ring seal
• Each piston is designed with the proper installed clearance to maximize power output, minimize wear, and optimize ring seal at running temperature
• Engineered, forged, and machined in the USA at Wiseco's facility in Mentor, OH
