The Cylinder Works Standard Bore Cylinder Kit is a ready-to-install, direct bolt-on replacement for the OEM cylinder. Designed for the 2004-2007 Honda CRF 250R, it requires no re-plating and closely matches the stock appearance. The kit includes a nickel silicon carbide-plated cylinder for durability, along with a matched Vertex piston kit to enhance longevity, performance, and reduce engine noise. It comes complete with gaskets, piston, rings, pin, and clips for a hassle-free installation. This kit is intended exclusively for closed-course competition use and is not legal for use on public roads in California.
