Compact dimensions with an unbelievable power output, the KTM 350 XCF-W's fuel-injected DOHC engine offers the best power-to-weight ratio on the market, thanks to newly developed camshafts, exhaust system and updated electronic fuel injection. Its class-leading power delivery is available throughout the entire rev range. The weight is reduced to 61.7 lbs (28 kg), making it almost as light as a 250, while offering power and torque closer to a 450 cc.

The KTM 350 XCF-W has a reworked cylinder head design with a similar architecture as the 2019 KTM 350 EXC-F, but is now 200 gr lighter. The 2 new overhead camshafts and flow optimized ports guarantee outstanding, offroad-specific engine characteristics. The DLC coated finger followers, as well as the lightweight valves they actuate (intake 36.3 mm, exhaust 29.1 mm), allow for higher engine speeds, a crucial factor in the 350's dynamic performance. The new head also features a new cylinder head cover and gasket, as well as a new spark plug and spark plug connector.

The KTM 350 XCF-W's crankshaft is located in an ideal position close to the center of gravity, contributing to easier handling. It 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 engine's pressurized lubrication system provides the necessary oil feed for this bearing. This design has a direct benefit for the crankshaft with extended service intervals, which are lengthened due to the plain bearing. So just pin it, all day long.

The XCF-W models feature reworked engine cases, reducing the weight by nearly 300 gr. The design allows for a very centralized shaft configuration, making the engine very short and compact, while contributing to an efficient centralization of mass. Additionally, the engine covers feature a smart surface structure which reduces wear caused by the rider's boots, keeping them looking as fresh as the day you bought it.

The 350 XCF-W uses a new 6-speed transmission made by PANKL RACING SYSTEMS, that now features a stronger, forged raw material, ensuring the highest durability and reliability. There was no need to change the gear ratios that are perfectly matched to the power characteristics of the engine. All four-stroke engines are fitted with a gear 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 new 42 mm throttle body. There are separate systems for cold starting and idle adjustment, while an improved seal of the MAP sensor (MAP = Manifold-Absolute-Pressure) makes the system even more reliable. A reworked throttle cable mount allows for easy access and smoother routing of the cables. Additionally, for 2020, the ECU features new maps which have been adapted to the new exhaust, airbox and engine configuration, regulating the unique traction control and are activated by a 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.

The new, extremely short 88 mm bore cylinder features a reworked cooling concept that works together with the new, forged bridged box-type piston made by CP. The piston crown geometry has been adapted to suit the high-compression combustion chamber. Despite its incredibly low weight, it has an extra rigid structure for enhanced durability. Thanks to its lightweight construction, the oscillating masses are low, giving the engine extremely lively characteristics. To further improve engine performance, the compression ratio has been increased from 12.3 to 13.5:1.

The multifunctional side-mounted counter balance shaft masterfully balances all the oscillating forces, while also driving the water pump. It effectively keeps engine vibrations to a minimum, resulting in the smoothest ride even at the highest engine speeds.

The KTM 350 XCF-W is fitted with the extremely durable, KTM-developed DDS clutch (damped 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. The diaphragm spring is also compact enough to allow for a damping system to be integrated into the clutch hub, contributing to better traction and durability. 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 XCF-W 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.

Maintaining the optimal engine temperature and consistent horsepower throughout the ride, the KTM XCF-W range features newly designed radiators which are mounted 12 mm lower than the predecessors, lowering the center of gravity, matching the design of the new shrouds perfectly and providing perfect ergonomics. By using CFD technology (Computational Fluid Dynamics) and a smarter coolant circuit routing, the innovative system ensures optimum engine temperature for the highest performance, in all conditions. Above all, a reworked delta distributor, integrated into the frame triangle has a 4 mm larger center tube, increasing the cross section by 57%, so coolant flows from the cylinder head to the radiators more efficiently. 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 improved power delivery and performance, the new exhaust plays a key role and packs a punch that is hard to beat. All 4-stroke XCF-W models feature new, two-piece header pipes (two parts instead of one on the predecessor) which can now be disassembled much more easily and which allows better access to the shock. The aluminum muffler sleeve has a newly designed, slightly larger profile with a new end cap. Compared to the predecessors they are shorter and more compact, bringing the weight closer to the center of gravity for better mass centralization.

All XCF-W models feature new high-tech, lightweight chromoly steel frames. This includes hydro-formed elements produced by state-of-the-art robot welding. They retain their race-proven geometries, but by redesigning certain areas they now have a higher lateral, longitudinal and torsional stiffness, resulting in better feedback for the rider, playful handling and improved stability. The laterally attached engine head stays (the connection between cylinder, head and frame) are now made of aluminum, reducing vibration and further contributing to precise cornering. The bikes also feature newly designed 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 2 lbs (900 gr) and is 40 mm longer than before, providing better rear fender stability.

The KTM 350 XCF-W's one-piece aluminum swingarm is manufactured using a gravity die-cast production process, offering exceptional strength at the lowest possible weight. The single-component casting process offers low weight, perfect flex behavior and also allows for a large number of geometry solutions.

KTM uses lightweight, CNC-machined hubs and high-end GIANT rims on all Enduro models, guaranteeing maximum stability and minimum weight. The aluminum spoke nipples feature an innovative design, which conveniently reduces the frequency with which the spokes need to be tightened.

All XCF-W models are fitted with the latest 48 mm diameter, WP XPLOR upside-down forks, featuring a split fork design developed by WP and KTM. While each side is fitted with springs, they have separate damping functions. Compression damping is on the left and the rebound on the right. Both can easily be adjusted via the dials on top of both fork tubes with 30 clicks each. Although already distinguished for outstanding response and damping characteristics, the 2020 fork features a calibrated mid-valve piston for more constant damping. It also has new upper fork caps and clicker adjusters for easier adjustment with a new color and graphic design. The new settings keep the front end higher, providing increased reserves against bottoming out.

The WP XPLOR shock absorber is the key element in the proven PDS rear suspension design (progressive damping system), where the shock is directly linked to the swingarm without an additional linkage system. This keeps weight lower and reduces the chances of hooking on rocks. Optimal dual-sport specific damping progression is achieved by using a second damping piston in combination with a closed cup towards the end of the stroke, and supported by a progressive shock spring. For 2020, improvements to the second piston, as well as a reworked shape and sealing of the cup, lead to improved resistance against bottoming without any sacrifice of comfort. New settings on the XPLOR shock with PDS technology provide better damping characteristics and match the new frame and reworked front-end set-up perfectly. It is fully adjustable, including high and low-speed compression, so you can set the shock up to suit any track, trail and rider preferences.

These high-tech Brembo brakes 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 XCF-W range are fitted with newly designed 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 new airbox on the KTM 350 XCF-W has been completely reworked to ensure better flow dynamics, resulting in optimal power and throttle response. Despite the obvious performance enhancements, the new 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.

All KTM XCF-W 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. All models can be fitted with an optional ignition curve selector switch on the handlebar for selecting alternative maps. The rider also has the option to activate TRACTION CONTROL from this optional 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 up the pegs, even when digging in deep ruts. The pegs on the Enduro models are 6 mm higher than the ones used on SX models, which benefits ground clearance. But you can swap them at will.

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.

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 get tired.
