Cylinder Works 09-15 Kawasaki KX 450 F 450cc +2mm Big Bore Cylinder Kit

Cylinder Works is known for making well-built engine components that help riders get more out of their machines. This Big Bore Cylinder Kit is a prime example, designed to give your 2009-2015 Kawasaki KX 450 F a significant performance boost. It effectively increases your engine's displacement to 450cc with a +2mm bore, which translates directly into more horsepower and a more responsive feel when you twist the throttle.

What's really neat about this kit is that it comes with a hand-matched Vertex piston, a top-end gasket kit, and all the necessary O-rings. This all-in-one approach not only simplifies your rebuild but also offers a cost saving compared to sourcing each of these critical components separately from the OEM. The cylinder itself is constructed from a high-quality 2618 aluminum alloy, chosen for its excellent strength and durability, ensuring it can handle the increased demands of a bigger bore engine. While it maintains an OEM appearance, the performance-driven design is clear in the results you'll see on the track or trail.

When you're looking to get more power out of your KX 450 F, this kit is a solid option. It's designed to integrate with your existing engine setup, making the upgrade process more straightforward. You'll notice a real difference in acceleration and overall power output.
