Cylinder Works 21-22 Gas-Gas EX 250 F 250cc STD Bore High Compression Cylinder Kit 14.7:1 Comp.

This kit from Cylinder Works gives you everything you need to rebuild the top end of your 2021-2022 Gas-Gas EX 250 F. Inside the box, you'll find a cast aluminum cylinder from Cylinder Works, a Vertex piston, and all the necessary gaskets to get your engine back to its full potential. This is a standard bore kit, meaning it's designed to replace your original cylinder without needing to machine the crankcase, making installation more straightforward.

What sets this kit apart is the high compression piston, designed to achieve a 14.7:1 compression ratio. This means more power and improved throttle response when you get back on the trail. The cylinder itself features a nickel silicon carbide (NSC) electroplate bore. This advanced plating allows for very tight tolerances, which translates to less friction as the piston moves and exceptional durability over time. It's also precision diamond honed to exact dimensions, ensuring your piston rings seal properly and maintain oil retention for a healthy engine.

Compared to buying individual OEM parts, this kit offers a competitive way to restore your bike's horsepower and performance. It's a well-built package designed to get you back out there with renewed power.
