Cylinder Works 11-12 KTM 350 SX-F 350cc +2mm Big Bore Cylinder Kit 365cc 13.5:1 Comp. 90mm

This Cylinder Works Big Bore Cylinder Kit is designed for the 2011 and 2012 KTM 350 SX-F. It takes your stock 350cc engine and increases its displacement to 365cc, giving you a notable bump in horsepower and overall engine performance. This kit is built to look like an OEM cylinder but offers a significant performance upgrade.

The kit includes a hand-matched Vertex piston and a complete top-end gasket set with O-rings, making it a convenient all-in-one solution. This saves you the hassle of sourcing individual parts and often offers cost savings compared to buying OEM components separately. The cylinder itself is constructed from a high-quality 2618 aluminum alloy, chosen for its strength and durability, which is essential for handling the increased power and displacement. The compression ratio is set at 13.5:1, and the bore size is 90mm, representing a +2mm increase over stock.

When you're looking to get more out of your KTM 350 SX-F's engine, this big bore kit is a solid option. It's a comprehensive package that addresses the core components needed for a displacement increase, aiming to provide a noticeable improvement in power and torque.
