2015 KTM 350 SX-F Base

2015 KTM 350 SX-F

The 350 SX-F continually causes a real sensation! In 2013, it succeeded in winning the MX1 World Championship in commanding style for the third time in succession and in dominating the MX of Nations. Toni Cairoli clearly has complete control of this class with his 350 SX-F and he loves this ingenious concept of low weight, playful handling and rev-oriented engine characteristics. A unique recipe for success, from which professionals benefit just as much as amateurs.

• Frame

The modern frame design of the SX models, built from lightweight, high strength, chrome-molybdenum steel section tubes, combines maximum longitudinal stiffness with optimum torsional stiffness. A forged and milled cross-peice connects the two frame halves with the connecting rod of the linkage on the 2015 SX frame. Omission of the weld seams leads to very precise manufacturing tolerances and it saves another 60 grams of weight.

• Linkage / Shock Absorber

The revamped damping system for MY 2015 features a new linkage with optimized geometry. The flatter progression with a higher initial rate ensures greater stability and lowers the rear end. In addition, the new design saves another 40 grams of weight. The fully adjustable WP 5018 shock absorber has been completely retuned to suit the new linkage.

• Fork

The fully adjustable upside-down fork from WP Suspension has been perfectly tuned to the new rear wheel damping system and the new 22 mm front axle (formerly 26 mm) for MY 2015. The new axle provides a better feel for the front wheel and also saves a further 40 grams. The new fork stubs now feature an offset of 33 mm instead of 35 mm, which together with increased trail deliver greater ride stability. Furthermore, they accommodate newly developed, 50 gram lighter fork protectors.

• Triple Clamps

High quality, CNC-machined triple clamps have long since been standard equipment at KTM. They ensure precise handling and provide a perceptible boost to the flexing characteristics and hence the responsiveness of the telescopic fork. The new O-ring carrier for the lower steering head bearing, a revised shaft tube and the new steering head bolt save another 40 grams.

• Wheels

The wheels fitted for MY 2015 feature black coated, high-end Excel rims with lightweight, CNC-machined hubs and spokes with lightweight aluminium nipples, allowing highest levels of stability to be achieved, while keeping weight to a minimum. New Dunlop Geomax MX 52 tires were developed in collaboration with the KTM USA factory team and offer perfect traction with top performance. The new rear sprockets save 50 grams in unsprung mass.

• Brakes

High-tech brakes from Brembo have always been standard equipment on KTM offroad bikes and, together with the lightweight Galfer Wave brake discs, they are the measure of all things in terms of brake technology. As the best brakes in the motocross class, they remain unchanged for MY 2015.

• Cylinder Head

The DOHC cylinder head excels with ducts dimensioned for optimum flow, which ensure maximum gas throughput and therefore supreme cylinder charging. Ultra-light titanium valves and DLC-coated cam followers allow engine speeds of over 13,000 rpm to be achieved and ensure spontaneous power development plus high peak power that comes very close to that of a 450.
