What is the main benefit of the nickel silicon carbide (NSC) bore?

The NSC electroplate bore allows for tighter tolerances between the piston and cylinder wall. This results in lower friction and extreme durability, contributing to improved engine performance and longevity.

Does this kit include everything needed for installation?

Yes, this standard bore cylinder kit includes the Cylinder Works cylinder, a Vertex piston, and all the necessary gaskets to restore your engine's performance.

Is this cylinder kit a direct replacement for the original part?

This kit is designed as an OEM-style standard bore replacement. It aims to restore original horsepower and performance without requiring the original cylinder to be bored out.

About this part

Product Details

If you're looking to bring your 2021-2023 Yamaha WR 450 F back to its original power, this standard bore cylinder kit from Cylinder Works is a solid option. It's designed to replace your worn-out cylinder and piston, getting your engine running strong again without needing to bore out the original case. This kit aims to restore the horsepower and performance you expect from your WR 450 F.

Inside this kit, you'll find a cast aluminum cylinder from Cylinder Works, built to OEM specifications. It's paired with a Vertex piston, a well-known name in performance engine components. The cylinder features a nickel silicon carbide (NSC) electroplate bore. This advanced plating allows for tighter tolerances, which means less friction as the piston moves up and down. That tighter tolerance, combined with the precision diamond honing to exact dimensions and a proper surface finish, helps ensure your piston rings seal well against the cylinder wall. This good seal is crucial for both oil retention and consistent compression, contributing to the engine's overall health and performance.

This kit comes with all the necessary gaskets to complete the installation, making it a complete package to get your engine rebuilt. It's a competitive alternative to going with a full OEM replacement, offering a way to restore your bike's performance with quality components.
