About this part

Product Details

This kit from Cylinder Works gives you everything you need to get your Yamaha YZ 125 back to its original power. Inside this box, you'll find a cast aluminum Cylinder Works cylinder, a Vertex piston, and all the necessary gaskets to complete the job. It's designed as an OEM-style replacement, meaning it fits and functions just like the original part, but at a more competitive price point than going with a factory option.

The cylinder itself is built with a nickel silicon carbide (NSC) electroplate bore. This advanced plating technique allows for very tight tolerances, which helps reduce friction as the piston moves. It also contributes to extreme durability, so you can expect this cylinder to hold up well under use. To ensure optimal performance right from the start, the bore is precision diamond honed to exact dimensions. This creates the perfect surface finish for your piston rings to seal properly and retain oil, which is crucial for engine health and longevity.

When you're looking to restore the horsepower and performance of your 2005-2021 Yamaha YZ 125, this standard bore cylinder kit is a solid option. It includes the key components to get your engine running strong again.
