Cylinder Works 19-20 CRF 450 L/21-23 CRF 450 RL/19-23 CRF 450 X Big Bore Cylinder Kit

If you're looking to get more power out of your Honda CRF 450 L, RL, or X, this Big Bore Cylinder Kit from Cylinder Works is a solid option. It's designed to increase your engine's displacement and horsepower, giving you that extra edge whether you're on the trail or the track. This kit aims to give you that performance boost while keeping the appearance close to stock, so you get improved performance without a radical change in how your bike looks.

Inside this kit, you'll find a big bore Vertex piston that's been hand-matched to the cylinder. This careful pairing ensures a good seal and optimal performance right out of the box. The cylinder itself is made from a well-built 2618 aluminum alloy, which is known for being strong and durable, able to handle the increased demands of a larger displacement engine. You also get a complete top-end gasket kit, including O-rings, which means you have most of what you need to get the job done. Buying it as a kit can also save you some money compared to sourcing all the individual OEM parts separately.

When you're ready to install this kit, make sure to refer to the manufacturer's service manual for the correct procedures and torque specifications. Having the right tools and a clean workspace will make the installation process smoother. This kit is a significant upgrade for your CRF 450's engine, offering a noticeable increase in power and a more engaging riding experience.
