Featuring a compact and lightweight (60 lbs) construction, this DOHC (double overhead camshaft) design boasts lightweight titanium valves and Diamond-like Coating (DLC) cam followers allow for lively power across the rev range. As the 350 cc motor shares much of its design with the 250 cc 4-stroke mill, the KTM 350 XC-F has managed to pump out big power, but remain as nimble as a smaller machine, making it the perfect middleweight monster.
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 13,400rpm. 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.
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 SX-F will keep looking better longer.
The KTM 350 XC-F features a robust 6-speed transmission made by PANKL Racing Systems. The gears are made of a strong, forged raw material and feature a special surface treatment on the 2nd, 3rd and 4th gear, ensuring the highest durability and reliability level. 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 state-of-the-art Keihin Engine Management System, with electronic fuel injection, features a 44 mm throttle body with separate systems for cold starting and idle adjustment. The throttle cable mount allows for easy access and a smooth routing of the cables. The ECU features selectable engine maps which are optimized to the exhaust, airbox and engine configuration, as well as regulating the unique traction control and launch control which are activated by the handlebar map-select switch. It also provides different maps for each gear, according to the information received from the gear sensor, ensuring maximum power as you shift through the gears.
Inside the short 88 mm bore cylinder, is an extremely lightweight, forged bridged box-type piston made by CP. Its crown geometry is adapted perfectly to the high-compression combustion chamber (14:1), where its rigid structure and low weight shine. Thanks to the low oscillating masses, the engine is both snappy and strong.
To balance the mass-forces, the KTM 350 SX-F engine uses a multifunctional balancer shaft, which at the same time drives the water pump and timing chain.
The KTM 350 XC-F is fitted with the extremely durable, KTM-developed DS clutch (diaphragm steel), with a wear-free steel basket and heat resistant clutch plates. It uses a diaphragm spring instead of the usual coil springs, which results in considerably easier clutch action. Additionally, the Brembo hydraulic system provides easy and precise clutch modulation throughout the entire operating temperature range.
The standard electric starter on the KTM 350 XC-F uses a proven starter drive and a strong starter motor made by Mitsuba. As demonstrated time and time again, it provides quick and reliable starting, saving you precious time and energy when you need it most.
With one touch of a button, the map switch gives the rider the chance to select between a standard map setting and a more aggressive map for loamy, high grip dirt conditions. This is particularly useful for changing track conditions or for a rider that is looking for more control as he begins to fatigue.
Maintaining the optimal engine temperature is crucial to ensuring consistent horsepower throughout the ride. The KTM 350 XC-F features radiators which are mounted close to the center of gravity and match the design of the shrouds perfectly, in order to achieve perfect ergonomics. By using CFD technology (Computational Fluid Dynamics) and a smart coolant circuit routing, the innovative system ensures optimum engine temperature for the highest performance, in all conditions. Above all, the delta distributor, integrated into the frame triangle, features a large center tube, making the coolant flow from the cylinder head to the radiators highly efficient. The radiators have special protectors that protect from flying rocks and debris while also acting as a brace to disperse energy around the radiators in the event of an impact.
When it comes to power delivery and performance, the exhaust on all 4-stroke models plays a key role and packs a punch that is hard to beat. It features a model specific header pipe with an advanced resonator called FDH (Flow Design Header), which is a small chamber around the pipe. The design allows the exhaust to be disassembled without removing the shock absorber and also provides better access to the shock. The aluminum sleeve, end cap and internal design of the silencer allows for slimmer ergonomics, making the bike feel narrower, without compromise to regulatory noise limits.
All XC models feature high-tech, lightweight chromoly steel frames. This includes hydro-formed elements produced by state-of-the-art robot welding. With its race-proven geometries and optimal stiffness, the frame provides great feedback for the rider, playful handling and remarkable stability. The laterally attached engine head stays (the connection between cylinder, head and frame) are made of aluminum, reducing vibration and further contributing to precise cornering. The bikes also feature lateral frame guards with a structured surface, improving grip, while also serving as a heat protector against the muffler on the right side. The subframe is made of extra-light and stable aluminum profiles, weighing less than 900 gr, providing great rear fender stability.
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.
The KTM 350 XC-F is fitted with lightweight, CNC-machined hubs, high-end Giant rims and black spokes with lightweight aluminum nipples providing maximum stability at minimum weight. The latest Dunlop Geomax AT81 tires guarantee perfect traction and outstanding performance.
All XC models are fitted with the latest 48 mm diameter WP XACT upside-down forks, featuring a split air fork design with seperate functions for each leg. That means damping functions are on the right side, whereas the air spring is in the left. This left leg features a 2-chamber system with a capsuled air cartridge to prevent loss of air pressure. Should the outer seal start to leak, the internal cartridge pressure will keep the bike in position. The air spring is easy to adjust to any rider weight via a single air valve. Additionally, the fork can be adjusted to the track conditions and the rider’s preferences with a twist of a dial (compression from the top, rebound from the bottom, 30 clicks each). New for this year, the pressure peaks were reduced through extended oil and air bypasses. In combination with the new midvalve damping system, this fork is more comfortable and more sensitive than ever right off the dealer floor. But you can still hammer the hell out of it.
The WP XACT shock absorber has been developed with the entire frame and swingarm architecture in mind, including the linkage system and the WP XACT front forks. It features machined and anodized components and is a valuable, high-end product compared to roughcast reservoirs. A new, confidence inspiring setting with low-friction linkage seals for improved damping characteristics perfectly matches the front-end set-up and its WP color scheme lets everyone know you have excellent taste in suspension.
Top quality, CNC machined triple clamps have been a KTM trademark for years to ensure precise handling. The rubber damped handlebar fixation allows for two positions and an hourmeter is fitted in order to let the rider know it’s time for a service.
These high-tech Brembo babies are combined with lightweight Wave brake discs. You couldn’t brake any harder or with better feel on an offroad motorcycle.
All models in the XC range are fitted with lightweight polyethylene tanks improving the ergonomics. The ¼‐turn bayonet filler cap makes for quick and easy closure. Manufactured using see‐through plastic, you will always be able to see how much fuel remains at a glance. It is fitted with an integrated fuel pump system and a fuel level sensor. Additionally, the fuel line features a 90° connector to the tank for better protection against damage.
The airbox on the KTM 350 XC-F ensures optimal flow dynamics, and together with the intake snorkels, results in optimal power and throttle response. Despite the obvious performance enhancements, the design also offers maximum protection against soiling of the air filter. The large Twin-Air air filter is mounted on a cleverly designed stiff cage that minimizes incorrect installation. As found on previous models, filter maintenance is quick and easy and does not require tools – a standard, original feature from KTM.
Ergonomically perfect, the seat has a high foam volume, which offers great comfort and durability, while keeping the weight low.
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.
The durable in-mold graphics convey the READY TO RACE character of the KTM XC-F model line.
All engines are fitted with the proven electric starter, which is a major benefit for any offroad activity. It is powered by a super lightweight 2 Ah lithium-ion starter battery, which provides safe, reliable starting. The wiring harness has most of the electrical components carefully positioned into a common area below the seat, making them easily accessible and reliable.
TRACTION CONTROL is a highly beneficial feature that guarantees more efficient traction and better control of the bike when accelerating on wet or slippery hard pack surfaces. It can be activated by the handlebar map switch during riding.
