What is included in this cylinder kit?

This kit includes a cast aluminum Cylinder Works cylinder, a Vertex piston, and all the gaskets needed to install the cylinder and piston assembly.

What makes the Nickel Silicon Carbide bore special?

The Nickel Silicon Carbide (NSC) electroplate bore allows for tighter tolerances, which reduces friction during piston movement. This also contributes to the extreme durability of the cylinder.

How does the diamond honing affect performance?

Precision diamond honing ensures the cylinder bore is to exact dimensions with the proper surface finish. This is critical for achieving a good seal with the piston rings and for retaining oil, which is essential for lubrication.

About this part

Product Details

This Cylinder Works standard bore cylinder kit is built for your 2019-2020 Yamaha WR 450 F. If you're looking to bring your engine back to its original performance levels, this kit is a solid option. It includes a cast aluminum cylinder from Cylinder Works, a Vertex piston, and all the necessary gaskets to get your engine running right again. It's a way to restore horsepower and performance without going the OEM route, often at a more competitive price point.

What sets this cylinder apart is its Nickel Silicon Carbide (NSC) electroplate bore. This advanced plating allows for very tight tolerances, which means less friction as the piston moves up and down. That lower friction translates to better efficiency and helps with the extreme durability of the cylinder. The bore is also precision diamond honed to exact dimensions, ensuring the piston rings seal properly against the cylinder wall. This precise surface finish is crucial for good ring seal and also helps with oil retention, keeping your engine properly lubricated.

When you're rebuilding the top end of your WR 450 F, having a well-made cylinder and piston is key. This kit aims to provide that, giving you the parts needed to get your bike back on the trail with renewed power.
