Wiseco CK186 Forged Piston Kit Compression - 4-Stroke 75mm 13.2 1

The Wiseco CK186 is a complete 4-Stroke Forged Piston Kit featuring a 75.00mm bore and 13.2:1 compression ratio, purpose-built for high-performance Honda CBR1000RR engines. Engineered, forged, and machined in the USA at Wiseco's facility in Mentor, OH, this kit delivers the ultimate combination of performance, strength, and reliability.

Key Features:

• Aerospace-grade forged aluminum construction — forging compresses the material's molecules, increasing density and aligning grain flow for superior impact resistance, fatigue resistance, and ductility compared to cast pistons
• Application-specific design — engineered and built to the tightest tolerances for this specific 4-stroke engine, optimizing the strength-to-weight ratio
• CNC diamond-turned finish — precision machined on CNC turning centers for a perfect finish with zero size variation, compatible with cast iron, chrome, nikasil, and boron composite cylinder bore compositions
• 3D design and finite element modeling — Wiseco engineers use the latest modeling software to ensure every piston delivers maximum strength at minimum weight
• Complete kit — includes forged pistons, high-quality piston rings, wrist pin(s), and circlips — everything needed for a top-end rebuild
• Made in the USA — Wiseco is the only U.S. aftermarket piston manufacturer that exclusively uses the forging process, controlling every step from raw material to finished skirt coating

The Wiseco CK186 piston kit is proven at every level of riding and racing, making it an ideal choice for both competitive track use and performance street riding. With decades of motorsports heritage and rigorous field testing, Wiseco pistons are built to meet the demands of the most serious riders.
