Cylinder Works 15-17 Yamaha WR 250 F 250cc Standard Bore High Compression Cylinder Kit 14.2:1 Comp.

Cylinder Works is known for providing well-built engine components that help riders get back on the road or trail. This high compression cylinder kit is designed for the 2015-2017 Yamaha WR 250 F, aiming to restore lost horsepower and performance. It features a standard bore size, meaning it matches the original cylinder dimensions, making installation more straightforward.

This kit includes a cast aluminum Cylinder Works cylinder, a Vertex Piston, and all the necessary gaskets to complete the job. The cylinder itself is treated with a nickel silicon carbide (NSC) electroplate bore. This advanced plating allows for tighter tolerances, which translates to lower friction during operation and extreme durability over time. The bore is also precision diamond honed to exact dimensions, ensuring a proper surface finish that helps with ring seal and oil retention, crucial for efficient combustion and engine longevity. With a 14.2:1 compression ratio, this kit is built for riders looking for an improved power output from their machine.

When rebuilding your engine, using a complete kit like this ensures all the core components are designed to work together seamlessly. This can save you time and potential headaches compared to sourcing individual parts. Always refer to the manufacturer's service manual for specific installation procedures and torque specifications.
