A completely redesigned engine, significantly lighter with a pioneering injection system guarantees raw but controllable power. Surrounded by a greatly improved chassis in terms of fairings, frame and suspension, the 2013 KTM 450 SX? F sets new benchmarks in the 450 four-stroke class in terms of handling and performance..
Motor
Lower weight, less maintenance. But since some things cannot be reduced, the 449.3 cm SOHC SX-F engine³ (27.418 cu in) gives the 2013 model a big advantage: more power. Take the 2 kilos saved thanks to a more compact architecture and add the 60 hp to obtain incomparable power and handling never before seen in the MX1 class.
Cylinder head
Precision Technology: A reconfigured cylinder head for ideal motocross characteristics with a very wide useful rev range. Extremely compact and lightweight architecture, a single camshaft specially designed for the KTM SX-F with low weight rocker arms (DLC coated on the intake side) that control four titanium valves. With extra-light valve springs and spring cups, enough to reach a maximum speed of up to 11,500 1 / min for optimum power.
Linkage
The crankshaft of the new KTM 450 SX? F with 63.4 mm (2.496 in) of travel is fitted in 2013 with a revolutionary sliding bearing in the bottom of the big end eye. This means that the classic needle bearing is replaced by 2 bearings pressed into the ultra-light Pankl connecting rod, directly connected to the reinforced crank pin of the crankshaft. The plain bearing is supplied with oil directly by the compressed oil circuit via the crankshaft. In other words: No more problems in terms of speed limits, and half the maintenance of the crankshaft. And as the moving masses are reduced, the bike has more bite, is more agile and more dynamic..
Framework
Very modern, the frame design in lightweight, high-strength chrome-molybdenum profile tubes guarantees the perfect blend of longitudinal stiffness and torsional stiffness. This not only offers good handling and precise steering, but also excellent driving stability. The four-stroke frames shine on the 2013 models by stiffening the frame triangle and thinner-walled tubes. This improves stability (increased resistance to torsion) while reducing weight. The optimization also focused on the engine mountings to the cylinder head as well as their connection to the frame. The 2013 KTM 450 SX? F frames feature a new color and remain a benchmark in terms of weight and stability.
Fork
Further improved, the closed cartridge 48 mm (1.89 in) inverted fork benefits from fully optimized tuning and a new oil specification for perfect match with new frames and engines. This new oil is much more resistant to wear and guarantees more constant damping both over the course of the stroke and over the life cycle. The new lower triple tree is 80 g (2.82 oz) lighter, and like the upper triple tree, it has been CNC milled from high quality aluminum to significantly improve damping characteristics and fork response.
Swinging arm
The cast aluminum swingarm was designed using state-of-the-art calculation and simulation software; the design and thickness of the walls ensure minimum weight for optimum strength and sufficient flex. For 2013 models, engineers changed the design of the rear of the swingarms to fit a more robust rear wheel axle (25 mm (0.98 in) instead of 20 mm (0.79 in). )) for better handling. In addition, weight reduction of over 100 g (3.53 oz) was achieved through modification of pins, cups and steering nuts..
Clutch
The new KTM SX-F engine incorporates a DDS (Damped Diaphragm Steel) damped clutch with wear-resistant steel bell that allows the use of thinner steel blades for minimum integration width. Spring washers that provide preload reduce operating forces and leave room for the integrated hub damping. The result: more traction and a less strained gearbox. And with Brembo’s hydraulically actuated clutch, the rider has it all under control from the start.
Electric starter
Every millisecond counts at startup. That’s why one button is now enough to start the new KTM 450 SX? F. An invaluable advantage in the heat of motocross action.
Dressing
The completely redesigned fairing is a clear signal, and not just from an aesthetic point of view, that the 2013 vintage represents a whole new generation of SX. In particular the ergonomics and functionality of the new plastics are designed so that the entire chassis and engine form a whole in every detail, in perfect harmony with the rider. Tank and deflectors have been given a makeover, as have the covers of the air box and the front fender, plate included. We can for example point out the front mudguard, which no longer has any ribs on its inner face in order to avoid any accumulation of mud. This innovative structure, combined with improved attachment of the mudguard to the triple tree, results in an increase in lateral torsion resistance by up to 50%..
