Cylinder Works Standard Bore Cylinder Kit Honda CRF250R 2010-2013 10007-K01

When you're pushing a CRF250R to its limits, factory tolerances become a ceiling, not a target. The Cylinder Works Standard Bore Kit delivers a bolt-on refresh that restores compression, improves ring seal, and eliminates the guesswork of sourcing matched components. This is precision engineering built to last—no machine work, no plating delays, just reliable performance out of the box.

Built with Nickel Silicon Carbide plating, the cylinder resists wear far longer than stock while the matched Vertex pistons ensure consistent ring tension and minimal blow-by. You get the durability of a fresh top-end without the downtime or complexity of a full rebuild.
