2021 KTM 350 XC-F

Taking lesson learned from Tony Cairoli's dominating career aboard the 350 SX-F, and insights from top 350 EXC-F enduro riders, we created the KTM 350 XC-F. Sharing the same aggressive motocross personality but with a refined chassis setup, state-of-the-art motor internals and EMS, the 350 XC-F, like Tony, is a flat-out, offroad-ripping legend!

ENGINE & EXHAUST

• ENGINE

The engine of the KTM 350 XC-F features a compact and very light (60 lbs) construction. Its DOHC (double overheard camshaft) design with lightweight titanium valves and DLC coated cam followers allows for lively but strong engine characteristics. Fitted with the latest electronic fuel injection system and an E-starter, it has an extremely wide usable speed range, high performance and incredibly efficient rideability. The KTM 350 XC-F engine shares the same layout as the 250 XC-F, resulting in playful handling that is similar to a 250 machine.

• CYLINDER HEAD

The cylinder head features two overhead camshafts with friction-optimized cam followers boasting a DLC coating and high-flow ports. Four lightweight titanium valves maximize the flow rate for an optimal power band and outstanding performance across the seemingly endless rev range of 13,400 RPM. Lateral brackets made of aluminum allow an efficient fixation of the engine to the frame and contribute to the bike's featherweight feel.

CHASSIS

• FRAME

The high-tech, lightweight chrome-moly steel frame has a knack for easy handling, outlandish rideability, precise cornering and excellent stability. You can also count on precisely calculated stiffness of the frame. This results in better absorption of the energy created from the front and rear suspension, sucking up jumps and bumps. In short: more comfort and less rider fatigue. Laterally attached, lightweight aluminum engine head stays (the connection between cylinder head and frame) contribute to more precise cornering and a reduced vibration level. The engineers were able to pull off all that, while making their frame 2.2 pounds lighter than that of the lightest competitor on the market. In addition, it is easier to maintain, easier to work on and supplies more space for the tank and other components. The bike also features an extra-light subframe made of aluminum, which tips the scales at less than 2 pounds.

• SWINGARM

The cast aluminum design offers low weight and a perfect flex behavior. The single-component casting process eliminates any inconsistencies and inherent weak points created by welding. It's better looking too.
