ENGINE

ENGINE MANAGEMENT SYSTEM (EMS)
In combination with the revolutionary injector position as developed by KTM, the Keihin Engine Management System with electronic fuel injection and 44mm throttle body provides the engine with a spontaneous response and maximum performance. For 2014, the wire harness of the 350 XC-F has been further simplified and even higher quality wires and connectors are used. In order to protect them against pressure washers, many connectors are now enclosed in new rubber boots. With an optional map-select switch from the PowerParts program, EMS continues to allow selecting different engine characteristics. In addition, the optional User-Setting-Tool allows to readout engine data with a laptop and change the ignition and injection mappings with a few mouse clicks.

TRANSMISSION
XC Semi-close ration 6-speed gearbox.
|
BALANCER SHAFT
In order to balance the mass-forces, the 350 engine uses a multifunctional counter balance shaft which also drives the water pump and timing chain. The engine receives a new water pump cover with a new gasket in order to optimize the seal.
|
CYLINDER HEAD
The DOHC Cylinder head is distinguished by ports dimensioned for optimum gas flow that ensure a maximized cylinder charge. Ultralightweight titanium valves and DLC-coated followers allow engine speeds up to 13,000 rpm, as well as ensuring a spontaneous power delivery as well as a high maximum power very close to a 450.
|
CLUTCH
The highly compact CSS (coil spring steel) clutch uses a wear-free steel basket and eight clutch plates which are extremely heat resistant due to their steel carrier discs. The Brembo hydraulic system with its new master cylinder provides easy and precise modulation.
|
STARTER
The 350 XC-F is fitted with an electric starter as standard – an undisputed advantage when it comes to crunch time in the heat of battle. In 2014, A newly developed freewheel assembly is used to increase durability.
|
CRANKSHAFT
The 350’s crankshaft employs a plain big end bearing. Two force-fitted bearing shells run directly on the crank pin. The necessary oil feed for this bearing is ensured by the engine’ s pressure lubrication.This design is a major prerequisite for the high engine speed levels and the impressive maximum power of the 350cc engine. Another decisive customer benefit is the crankshaft service interval which could be lengthened due to the plain bearing.
|
ENGINE
The 350cc four-stroke engine, with state-of-the-art electronic fuel injection, provides a very broad useable rev range and distinguishes itself with dynamic yet strength-saving engine characteristics.

SUPERIOR CHASSIS
|
TRIPLE CLAMPS
The lower triple clamp has been modified for optimum attachment of the new front fender. Thanks to its new contour and attachment with two bolts from the front and two from below, the new fender boasts significantly higher stability.
|
EXHAUST SYSTEM
The new 350 & 450 have an optimized silencer that achieves outstanding performance at low noise levels. In addition, hydro-formed sections and an additional resonator (Header Resonator System,HRS) provide the 250 and 350 models with extra torque while reducing their noise emissions.
|
SWINGARM
The cast aluminium swingarm has been developed with state-of-the-art calculation and simulation software and constructed, in terms of design and wall thickness, for minimum weight with optimum stiffness and precisely defined flexibility. For the 2014 model year, our engineers have revised the chainguide for the benefit of higher functional reliability, while simultaneously reducing the weight.
|
SUSPENSION/DAMPING
For 2014, all XC models are fitted with a newly developed 48mm 4CS Closed Cartridge fork featuring the patented 4-Chamber-System. The sophisticated design provides very constant and sensitive damping characteristics and an adjustable end progression. The new hand click adjuster system is now accessible on top of the fork, rebound on the right hand side, compression on the left. The fork is fitted with improved seal rings made by SKF and high performance fork oil (SAE 4). Compared to the predecessor, the new 4CS fork is lighter , easier to maintain and has been completely valved to match the shock for XC racing.
|
FRAME
The state-of-the-art frame design made of lightweight, high-strength chromoly steel sections combines maximum longitudinal stiffness with optimum torsional rigidity. It guarantees easy handling and precise cornering, but also outstanding stability.

BODYWORK
|
SEAT
Ergonomically perfect, the seat has received an improved foam core, ensuring greater comfort and durability.
|
AIR BOX
The airbox design offers maximum protection of the air filter against dirt while ensuring maximum airflow for top performance. The Twin Air filter can be changed without tools in seconds, a standard for KTM.
|
BODYWORK
In shaping the bodywork, the KTM designers’ ergonomic and design focus was to achieve complete harmony between rider and bike, down to the finest details. The front fender is a prime example of a moulded polymer component gaining maximum stability through a well thought-out structure and mounting. XC models come with hand guards and side stand
|
HANDLEBAR
All SX & XC models are fitted with the super strong, tapered Renthal Fatbar 827 whose bend is especially well suited to the requirements of racing. The proven standard KTM mount allows to fix the handlebar in four different positions. A large Renthal bar pad in a classy combination of black and silver, offers effective crash protection for the rider.
|
FUEL TANK
All models of the XC range have high capacity translucent fuel tanks for cross country racing. The XC's have a new 1/4 turn fuel cap with an improved opening mechanism to make fueling during a race even easier.
|
GRAPHICS
New, classy graphics with clear lines visually underscore the exacting standards of what KTM deems a true, cutting-edge bike.

WHEELS AND BRAKES
|
BRAKES
High-Tech Brembo brakes have always been standard equipment on KTM offroad bikes. Combined with the lightweight Wave discs, they are the ultimate solution in braking technology. The SX/XC models gain a newly developed master cylinder with a new reservoir , a smaller piston diameter and optimized lever kinematics. Combined with new brake pads, this makes for another perceptible improvement of front brake performance and action.
• New master cylinder with new reservoir, new lever, optimized kinematics and smaller piston diameter (down from 10mm to 9mm).
• New colors on master cylinder and reservoir (sand blasted aluminum with black cap).
• New brake pads.
|
WHEELS
The wheels use lightweight, CNC-machined hubs, high-endrims and spokes coated in black with lightweight aluminumnipples to achieve maximum stability at minimum weight. The OEM Dunlop Geomax MX51 tires deliver perfect traction and outstanding performance. XC models come with an 18" rear wheel and Giant rims.
