This big bore cylinder kit is designed to give your Yamaha WR 450 F a significant boost in power and displacement. It's an all-in-one solution that makes upgrading your engine's performance more straightforward and cost-effective than sourcing individual parts.

This kit features a cylinder that looks like the original but is built for improved performance. It comes with a Vertex piston that's hand-matched to the cylinder for a precise fit. The cylinder itself is constructed from a 2618 aluminum alloy, which is chosen for its strong and durable properties, helping it withstand the increased demands of a larger displacement engine. By increasing the engine's displacement to 470cc, this kit raises horsepower and gives your WR 450 F a more potent feel.

Included in this kit is a complete top-end gasket set with o-rings, so you have everything you need to get the job done. This approach saves you money compared to buying each OEM component separately and ensures you have the correct parts for a proper seal and reliable operation.
