350 XC-F 2020
KTM 350 XC-F for Sale at Virginia KTM in Virginia, QLD | Specifications and Review Information
The Ultimate Combo
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 all-new KTM 350 XC-F. Sharing the same aggressive motocross personality but with a refined chassis setup, reworked motor internals and improved EMS, the 350 XC-F, like Tony, is a flat-out, offroad-ripping legend!
The KTM 350 SX-F's crankshaft utilises 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 pressurised 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 cylinder head features two overhead camshafts with friction-optimised cam followers boasting a DLC coating and high-flow ports. Four lightweight titanium valves maximise the flow rate for an optimal power band and outstanding performance across the seemingly endless rev range of 13,400rpm. Lateral brackets made of aluminium allow an efficient fixation of the engine to the frame and contribute to the bike's featherweight feel.
CRANKCASES AND ENGINE COVERS
The design of the die-cast crankcases allows for minimal weight and a very centralised shaft configuration. This makes the engine short and compact, while contributing to an efficient centralisation 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.
KTM's proven cooling system routes the coolant from the cylinder head through the frame triangle, directly to aluminium radiators made by WP. Thanks to flow optimised internal circulation and CFD-calculated ventilation, the system is superbly efficient. In addition, new radiator protections improve heat dissipation. Especially in the mud. They are also integrated into the front part of the shrouds to protect the radiators in a crash.
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 high torsional rigidity and low longitudinal stiffness. 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 aluminium 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 aluminium, which tips the scales at less than 2 pounds.
The cast aluminium design offers low weight and a perfect flex behaviour. The single-component casting process eliminates any inconsistencies and inherent weak points created by welding. It's better looking too.
The 350 XC-F is fitted with lightweight, CNC-machined hubs, high-end Giant rims and black spokes with lightweight aluminium nipples providing maximum stability at minimum weight. The latest Dunlop Geomax AT81 tires guarantee perfect traction and outstanding performance.
The lightweight WP AER 48 front fork, a 48 mm USD air-sprung fork developed by WP in close collaboration with KTM, is a split fork with separate 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. No extra special tools are required; the fork air pump is supplied with the bike. The right fork leg integrates a damping cartridge that tailors to all your damping needs. It 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). Right off the dealer floor, this fork (with reworked damping characteristics) is more comfortable and more sensitive than ever. But you can still hammer the hell out of it.
The WP shock absorber has been developed with the entire frame and swingarm architecture in mind, including the linkage system and the WP AER 48 front forks. It features machined and black anodised components and is a valuable, high-end product compared to roughcast reservoirs. A new, confidence inspiring setting with improved damping characteristics perfectly matches the front-end set-up and its WP color scheme lets everyone know you have excellent taste in suspension.
These high-tech Brembo babies are combined with lightweight Wave brake discs. You couldn't brake any harder, better, faster or stronger.
All XC-F models have new lightweight polyethylene tanks fitted with an integrated fuel pump system and capacity of 2.25 gallons. Inside threads on the filler cap make for an easy and reliable closure.
The air filter box design offers maximum protection of the air filter against soiling, while ensuring maximum airflow. The large Twin Air filter is mounted in a stiff cage, which at the same time holds the system in place. This design is so simple, you could still pop a fresh one in with a face full of mud. Without tools. In seconds.
KTM engineers sure know how to handle handlebars. This tapered one, made of high-strength aluminium, is fixed in damped rubber mounts and has two different positions. ODI lock-on grips make grip changes easy and do not require any wire or glue to be secured.
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 2018 EXC models, which are 6mm higher than the SX versions.
Ergonomically perfect, the seat has a high foam volume, which offers great comfort and durability, while keeping the weight low.
A new, tailor-made kit and a Factory orange frame. Because in this sport, champs deserve to look the part regardless of the dirt.
BATTERY & WIRING HARNESS
A strong new lithium ion battery breathes life into the engine and contributes to low vehicle weight. The lightweight battery and wiring harness are centralised 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.
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.
The engine is fitted with a smooth 6-speed semi-close transmission, which features a special surface treatment on the 2nd, 3rd and 4th gears for best reliability. 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. For 2018, the transmission shaft gets a new C4 bearing that has a bigger overlap in the case. This guarantees better reliability even at extremely tough operating conditions.
ENGINE MANAGEMENT SYSTEM
The state-of-the-art Keihin engine management system with electronic fuel injection features a 44 mm throttle body. Thanks to its unique injector position, the engine's response is instantaneous. And to make life even easier, separate systems for cold starts and idle adjustment await you. The lightweight control unit features a unique traction and launch control system for lightning-quick response when the gate drops and maximum grip thanks to different maps that sync with to the gear you're in. It's also possible to unleash an even more powerful mapping via the handlebar map-select switch.
CYLINDER AND PISTON
Inside the short cylinder, with a bore of 88 mm, thumps a 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 SX-F employs the KTM-developed CSS clutch (coil spring steel) with a robust steel basket and extremely heat resistant clutch plates and new, nitrated steel liners reducing the wear. Light operation and telepathic amounts of control are standard with this hydraulic Brembo actuated clutch.
The KTM 350 SX-F is fitted with a unique E-starter as standard, which is a clear advantage when it comes to crunch time in the heat of battle. A strong starter motor made by Mitsuba will fire time and time again at the push of a button. Even under extreme conditions, thanks to its more heat resistant O-ring.
