Upgrade the top end of your compatible Husqvarna or KTM 450 with the Cylinder Works 95mm Standard Bore 12.75:1 High Compression Cylinder Kit. Designed as a direct replacement for standard-bore applications, this complete kit includes the cylinder, Vertex piston kit, and required gaskets for a reliable engine rebuild. Cylinder Works part number CW50009K01 is engineered to deliver strong performance while maintaining an appearance similar to the original equipment cylinder.
The nickel silicon carbide-plated cylinder provides a durable bore surface designed for extended service life, consistent piston operation, and reduced engine noise. The matched Vertex piston helps support longevity and performance, while the high-compression 12.75:1 configuration is suited to riders seeking improved top-end response and efficient power delivery. No machine work is needed for installation in applicable standard-bore applications.
Fitment includes select 2016–2018 KTM 450 SX-F and 450 XC-F models, the 2017 KTM 450 SX-F Factory Edition, and select 2017–2018 Husqvarna FX 450 and FS 450 models. Verify the motorcycle model and year before ordering. The top-end gasket kit does not include valve stem seals. Replacement pistons, gaskets, and ring sets are available separately for future maintenance.
