Cylinder Works 10-13 Honda CRF 250 R 250cc Standard Bore High Compression Cylinder Kit 14.1:1 Comp.

This Cylinder Works high compression cylinder kit is built for the 2010-2013 Honda CRF 250 R. It's designed to bring your engine back to its peak performance, giving you that lost horsepower and responsiveness you're looking for. If you're rebuilding the top end of your CRF 250 R, this kit offers a solid way to get back on the trail with confidence.

Inside this kit, you'll find a cast aluminum cylinder from Cylinder Works, a Vertex piston, and all the necessary gaskets to get the job done. The cylinder features a nickel silicon carbide (NSC) electroplate bore. This advanced plating allows for very tight tolerances, which means less friction as the piston moves and a bore that's built to last. It's also precision diamond honed to exact dimensions, ensuring your piston rings seal properly and retain oil effectively, which is crucial for engine health and consistent power delivery.

With a 14.1:1 compression ratio, this kit is intended for riders looking for improved performance over stock. It's a well-built option that compares favorably to OEM replacements, offering a way to restore your bike's power without breaking the bank. Make sure to refer to the manufacturer's installation instructions for specific details on assembly and break-in procedures.
