2012 KTM 350SX-F Review

The high flier

The initial idea was to line up in the motocross/450 class with a bike featuring reduced displacement, but all the advantages of a lighter bike. The final result was the birth of the 350 SX-F and foundations being laid for a legend. Its first victory in the first world championship race and the world championship title in its first season — what better proof could there be for the brilliance of this concept? The sensation of the 2010 MX season enters the next round with a revamped chassis and an even more robust clutch.

New for 2012 the 350 SX-F model is now equipped with Dunlop MX51 tires.

 

 

2012 KTM 350SX-F Features and Benefits

Engine

The compact, state-of-the-art DOHC four-stroke engine in the 350 SX-F, featuring electronic fuel injection and balancer shaft, excels with an extremely wide usable rev range, highly efficient ridability and performance practically matching that of a 450. Clear advantages: Less exertion for the rider and higher speed through the turns thanks to more efficient performance.

Valve train

In the cylinder head with two overhead camshafts, extremely lightweight, carbon-coated cam levers actuate four titanium valves.

Engine management (EMS)

The Keihin engine management system with electronic fuel injection ensures spontaneous responsiveness and maximum performance from the engine. Various engine characteristics can be activated with an optional map select switch.

Frame

The state-of-the-art frame on the 350 SX-F made from high-quality chrome-molybdenum steel is extremely light and torsion-resistant. It is also characterized by a particularly balanced geometry that combines playful handling with razor-sharp precision.

Telescopic fork

The further improved upside-down telescopic fork incorporating closed-cartridge technology now ensures even greater punch with a new setting. At the same time, the WP fork with 48 mm (1.89 in) outer tube diameter boosts the precise handling of the 350 SX-F.

Swingarm with linkage suspension

The linkage rear suspension on the 350 SX-F bolsters accurate handling and extreme traction. The lightweight aluminum swingarm is designed for optimum lateral stiffness. The linkage system along with the WP shock absorber provides a very high progressive feel along with wide adjustment ranges.

EMS

The Keihin engine management system with electronic fuel injection and electronic throttle valve control ensures spontaneous responsiveness and maximum performance from the engine. Various engine characteristics can be activated with an optional map select switch.

Electric starter

Years ago, KTM proved that an electric starter is very advantageous even in the tough sport of motocross. That’s why the 350 SX-F can also be started at the press of a button. For weight-saving fanatics and traditionalists, the electric starter can be removed and a kick starter installed in its place.

Bodywork

The bodywork of the 350 SX-F with the very slim seat and radiator shrouds, plus excellent contact points, perfect the bike’s ergonomics, making handling even simpler and more precise.
