Cylinder Works 2007 KTM 250 EXC-F 250cc +4mm Big Bore Cylinder Kit 276cc 13.3:1 Comp. 80mm

This Cylinder Works big bore cylinder kit starts with a precisely matched Vertex piston and a complete top-end gasket kit, including O-rings, all bundled together. It’s designed to look like your stock cylinder but perform like a race-tuned engine. The kit increases your engine's displacement from 250cc to 276cc, giving you more power and a noticeable boost in performance.

The cylinder itself is constructed from a 2618 aluminum alloy. This material is chosen for its strength and ability to handle the increased demands of a larger displacement engine, ensuring it holds up under pressure. By increasing the bore by 4mm to an 80mm diameter, this kit effectively raises your engine's horsepower and overall displacement, offering a significant upgrade over the original setup. It's a cost-effective way to get more performance compared to sourcing individual OEM parts.

This kit is a comprehensive solution for riders looking to get more out of their 2007 KTM 250 EXC-F. It provides everything needed to perform the big bore conversion, aiming for a direct fit and improved performance right out of the box.
