Cylinder Works 10006-K01 Standard Bore 12.0:1 High-Compression Cylinder Kit for Honda CRF450R

The Cylinder Works 10006-K01 Cylinder Kit is a complete standard-bore, high-compression top-end solution for select Honda CRF450R models. Designed for dependable replacement and performance-focused engine rebuilding, this kit includes the cylinder, piston kit, and required gaskets for a convenient installation. The 12.0:1 compression ratio helps support strong engine response while maintaining the fit and appearance of a stock-style cylinder.

Each Cylinder Works cylinder is nickel silicon carbide plated to promote long service life, consistent performance, and improved wear resistance. The cylinder is matched with a Vertex piston to help ensure longevity, reduce engine noise, and provide reliable operation under demanding riding conditions. No machining work is needed for standard applications, helping streamline the top-end replacement process.

Fitment: This Cylinder Works kit fits 2009, 2010, 2011, and 2012 Honda CRF450R motorcycles. The kit is intended as a replacement cylinder solution for standard-bore applications. The included top-end gasket kit does not include valve stem seals, so verify the condition and availability of those components before installation. Replacement pistons, gasket sets, and ring sets are also available separately for future service needs.
