Motorcycle specifications KTM300 EXC HARDENDURO 2026 In search of the extreme

Enduro is a discipline where surprises and difficulties can build to a crescendo. For those who dominate the terrain, you need a weapon - the kind that pushes nature beyond its hostility. For 2026, the KTM 300 EXC HARDENDURO benefits from major updates, with significant improvements to the suspension, cooling system and overall design, aimed at further enhancing its dominance over the toughest terrain.

Since its launch in 2024, the KTM 300 EXC HARDENDURO has become the flagship model in Katoche's Enduro range, bringing the expertise of the KTM Factory Racing team and a championship heritage to production models.

As the ultimate Enduro competition bike, the 300 EXC HARDENDURO 2026 receives a new design, with iconic KTM orange accented by a white and black color palette, a bright orange frame and orange anodized PowerParts.

Technical updates will excite extreme enduro fans, starting with the 48mm WP XACT Closed Cartridge fork, including basevalve preload adjustment, as well as the updated WP XPLOR PDS shock to keep the package perfectly balanced.

The fork gets new damping settings, new lighter and shorter springs, and a new pressure reservoir to match the new spring mount geometry. A new one-piece hydro-stop completes the front fork improvements, also saving 200 grams in overall weight.

On the fuel supply side, a new protective cap has been added to the CPC connector, offering not only better protection against external damage, but also preventing dust from penetrating the sides of the connector.

The cooling system has also been improved thanks to a new screw-on radiator cap, facilitating faster opening, with a radiator fan fitted as standard.
