The 350 XC-F is one of the most exciting enduro models in the 2021 KTM line-up. Not only is it a formidable mid-sized enduro machine, but it also comes with a special top-of-the-range variant that’s exclusive for 2021: the Kailub Russell edition. The stock 350 XC-F features the perfect balance of power and agility in a lightweight and compact package.
The European-made engine has been tweaked to meet Euro5 regulations, but apart from that, it’s the same old tried and tested unit that we’ve seen before. That is, it’s a 349.9cc single-cylinder four-stroke unit with impressive power, but in a compact and narrow body. It’s powerful, but also accessible—making it an ideal choice for both beginners and experienced riders.
Like most KTM motorcycles, it also features advanced suspension from WP. This model uses WP XACT suspension on the front and rear, rather than XPLOR units found on the XCF-W. Brembo brakes, GIANT rims, a NEKEN handlebar, and other goodies are also standard equipment.
2021 also brings an exclusive 350 XC-F variant to the table in the form of the 350 XC-F Kailub Russell. This model features a whole host of top-shelf accessories and components, including a more advanced WP suspension setup, a special slip-on exhaust from FMF, race-spec brakes, a Selle Dalla Valle seat, a Hinson clutch cover, a unique racing livery, and so much more.
For 2021, the 350 XC-F is available exclusively in KTM Orange, while the more advanced 350 XC-F Kailub Russell has an exclusive KTM Factory Racing livery.
The 2021 KTM 350 XC-F starts from $10,699 USD / $11,799 CAD.

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.
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.
The KTM 350 XC-F’s crankshaft utilizes a short connecting rod, which makes for an overall compact and lightweight engine with a snappy power delivery. A plain big (bottom) end bearing with two force-fitted bearing shells runs directly on the crank pin. The necessary oil feed for this bearing is ensured by the engine’s pressurized lubrication. This design is a decisive benefit in terms of the crankshaft service interval, which can be lengthened due to the plain bearing. So just pin it, all day long.
Crankcases and engine covers
The design of the die-cast crankcases allows for minimal weight and a very centralized shaft configuration. This makes the engine short and compact, while contributing to an efficient centralization of masses. The engine covers also feature a solid surface structure, which reduces the wear caused by the rider’s boots. This way, your XC-F will keep looking better longer.
The engine is fitted with a smooth 6-speed semi-close PANKL transmission made of new and stronger materials. An advanced ´No Dirt´ gear shift lever design prevents mud and sand from blocking the joint of the lever and guarantees trouble-free shifting. All 4-stroke engines are fitted with a gear position sensor, giving the option of different engine characteristics for each gear. The transmission shaft features a C4 bearing that has a bigger overlap and guarantees better reliability even at extremely tough operating conditions.
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.
All KTM XC models are equipped with the same high-strength aluminum tapered NEKEN handlebar. The handlebar allows for four different positions. The handlebars come standard with an ODI vulcanized grip on the right side and a comfortable ODI lock-on grip, which does not require any wire or glue, on the left. Additionally, the bike is fitted with a map-select switch on the handlebar for selecting alternative engine maps. The rider also has the option to activate TRACTION CONTROL from this switch; a unique feature which guarantees more efficient traction, especially in slippery conditions, and can be activated with the push of a button during riding.
Sophisticated ´No Dirt´ footpegs prevent clogging of the footpeg pivot, even when digging in deep ruts. Looking for a higher riding position? Then just mount the footpegs of the EXC models, which are 6 mm higher than the XC versions.
Battery & wiring harness
A strong lithium ion battery breathes life into the engine and contributes to low vehicle weight. The lightweight battery and wiring harness are centralized in a compartment above the air filter box, allowing the mechanic to remove the subframe without moving the electronics. A happy mechanic is a good mechanic.
