2014 KTM 350 SX-F

In the three years since the revolutionary 350 SX-F has been introduced, this bike has proven that it is possible to win the MX1 World Championship even with reduced displacement. Since then, Tony Cairoli has clearly dominated the class with the 350 SX-F, and in 2013, the Italian once again bets on the ingenious combination of low-weight, playful agility and a high-revving engine. A unique recipe for success that benefits amateurs and pros alike.

Pricing/Color Information

MSRP: $8,749.00



Wheels - The wheels use lighweight, CNC-machined hubs, high-end Excel rims and spokes coated in black with lightweight aluminum nipples to achieve maximum stability at minimum weight. The OEM Dunlop Geomax MX51 tires deliver perfect traction and outstanding performance.

Transmission - The 5-speed gear box has been adapted to the 350 SX-F's engine characterisitics and is distinguished by easy and precise shifting.

Clutch - The highly compact CSS (Coil Spring Steel) cltuch 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.

Cylinder Head - The DOHC cylinder head is distinguished by ports dimensioned for optimum gas flow that ensure a maximized cylinder charge. Ultra-lightweight 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.

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 wiring harness of the 350 SX-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 KTM 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.

Crankshaft - The 350 SX-F'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.

Counter Balancer Shaft - In order to balance the mass-forces, the 350 SX-F engine uses a multifunctional coutner balance shaft which also drives the water pump and timing chain. For 2013, the engine receives a new water pump cover with a new gasket in order to optimize the seal.

Starter - The 350 SX-F is fitted with an electric starter as standard - a clear advantage when it comes to crunch time in the heat of battle. In 2014, a newly-developed freewheel assembly is used to increase durability.

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.

Triple Clamps - Top-quality, CNC-machined triple clamps have been something of a KTM trademark. Ensuring a precise handling, they perceptibly support the flex characteristics, and with it, the fork's action.

Swingarm - Designed using the latest in calculation and simulation software, the design and wall thickness of the cast aluminum swingarm have been optimized for minimum weight at optimum stiffness and precisely defined flexibility provides perfect stability at minimum weight. For 2014, the engineers have revised the chain guide to increase reliability while lowering the weight.

Suspension/Damping - The rear monoshock as well as the 48mm upside-down front fork by WP Suspension guarantee the best response and damping characteristics. In 2014, the fork has more reserves against bottoming out thanks to their optimized setting. Of course, compression and rebound damping can be adjusted to the track conditions and the rider's preferences with a twist of the wrist - the rear monoshock even has separate high and low speed adjustments.

Exhaust System - The new hydro-formed sections of the exhaust system and additional resonator (Header Resonator System, HRS) provide the 350 SX-F models with extra torque while reducing their noise emissions.

Seat - Ergonomically perfect, the seat has received an improved foam core, ensuring greater comfort and durability.

Handlebar - All SX models are fitted with the super strong, tapered Renthal Fatbar 827 whose bend is especially well suited for the requirements of motocross. The proven standard KTM mount allows to fix the handlebar in four different positions. A large Renthal crash pad in a classy combination of black and silver, offers effective crash protection for the rider.

Air Box - The airbox design offers maximum protection of the air filter against soiling while ensuring maximum airflow for top performance. The Twin Air filter can be changed without tools in seconds, a standard for KTM.

Graphics - New classy graphics with clear lines visually underscore the exacting standards of what KTM deems a true, cutting-edge motocross bike.

Fuel Tank - All models of the SX range have a new, lightweight polythene tank with a capacity of 1.98 gallons. The new filler cap with the inside thread makes for an easier and reliable closure. The 4-stroke models have the same fuel pump system as the 4-stroke Enduro models, which makes it easy to fit a larger tank from the PowerParts program.

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.
