If you're rebuilding the top end of your 2010-2018 Yamaha WR450F, 2010-2017 YZ450F, 2016-2018 YZ450FX, or 2016-2018 YZ250, this standard bore cylinder kit from Cylinder Works is a solid option to get your engine running like new again. This kit is designed to bring back the horsepower and performance you expect from your machine, offering a competitive alternative to OEM parts.

What sets this cylinder apart is its construction. It features a cast aluminum cylinder with a nickel silicon carbide (NSC) electroplate bore. This advanced plating allows for tighter tolerances between the piston and cylinder wall, which means less friction and improved durability over time. The bore is also precision diamond honed to exact dimensions, ensuring a proper surface finish that helps the piston rings seal effectively and retain oil, crucial for consistent performance and engine longevity.

This kit comes complete with a Vertex piston and all the necessary gaskets to get your engine back together. It's a well-built replacement that focuses on restoring your bike's original power output without breaking the bank. Refer to the manufacturer's installation instructions for specific details on assembly and break-in procedures.
