Wiseco R1049 Honda CBR1000F 4-Stroke Forged Top End Piston Kit 79mm 12:1

The Wiseco R1049 is a complete forged top end piston kit engineered specifically for the Honda CBR1000F. Featuring a 79.00mm bore and a performance-oriented 12:1 compression ratio, this kit is built to deliver a noticeable improvement in power output and engine reliability over a stock or worn piston assembly.

Key Features:

• Forged aerospace-grade aluminum construction — Wiseco is the only U.S. aftermarket piston manufacturer that uses exclusively the forging process, compressing the material's molecular structure for superior density, impact resistance, and fatigue strength compared to cast alternatives
• Dedicated forgings for an optimized strength-to-weight ratio tailored to this specific engine application
• Race-ready dome finish with smooth edges designed to improve combustion flow and efficiency
• ArmorGlide skirt coating reduces friction and noise while contributing to increased horsepower output
• Complete kit includes piston, high-performance ring set, alloy wrist pin, and circlips — everything needed for a proper top end rebuild
• Engineered, forged, and machined in the USA at Wiseco's facility in Mentor, OH
• 2.00mm oversize (79.00mm) — ideal for engines requiring a bore refresh or performance overbore

Wiseco's 4-stroke forged piston kits are proven at every level of riding and are built to the tightest tolerances for the ultimate combination of performance and long-term reliability. The R1049 is the go-to choice for CBR1000F owners looking to restore or upgrade their top end with a trusted, race-heritage component.
