Cylinder Works Standard Bore Cylinder Kit Honda CRF450R 2017-2018 10001-K01

Stock cylinder wear limits your CRF450R's potential, whether you're chasing track times or extending engine life on your rebuild. The Cylinder Works Standard Bore Kit delivers a direct bolt-on solution with matched components—no machine work, no guesswork. You get a complete, dyno-ready assembly that restores lost compression and adds measurable power while maintaining the reliability you need for consistent performance.

This kit pairs a nickel silicon carbide-plated cylinder with a Vertex piston engineered for the CRF450R platform. The plating reduces friction and resists wear, while the matched piston-ring-pin assembly ensures proper ring seating and longevity. Everything ships as one complete package—gaskets, clips, and hardware included—so you can go from box to running engine without sourcing individual components or paying for port work.
