With its rugged and unstoppable character the KTM 450 EXC is able to deal with any type of terrain with poise. Moreover, its compact design and the stiff frame help it move with agility.
At the heart of the motorcycle lies a 1-cylinder 4-stroke, water-cooled engine with a displacement of 449.3 cc.
The stopping power is assured by Brembo brakes which include wave brake discs (260 mm front and 220mm rear). The further refined rear brake cylinder has a new internal mechanism that ensures less wear at the rubber seal and therefore greater durability.
The motorcycle rides on a pair of high quality KTM wheels with CNC-machined hubs. The wheels are wrapped in new MAXXIS FIM tyres which offer excellent traction.
The ride is kept in check by a front WP suspension up side down and a rear WP Suspension shock absorber.

The KTM 450 EXC is without doubt one of the best motorcycles in its class. Compact design, very easy maintenance and outstanding robustness at a minimum weight - these are the characteristics of the SOHC engine. Together with the EFI system from Keihin, this results in unrivalled performance and rideability - specially designed for enduro bikes.
In keeping with KTM tradition, the frames are made from high quality, lightweight, chrome-molybdenum steel profiles. In conjunction with the rear PDS damping system, they are designed for optimum absorption of shocks introduced into the frame by the rear wheel. In response to the trend for aluminium frames followed by our rivals, we supply a high-tech steel frame that weighs approx. 0.5 kg less than the lightest competitor. Moreover, it’s easier to maintain, work on it is simpler and it provides more space for the fuel tank and other components.
Brakes from Brembo® are standard equipment on KTM offroad bikes and, together with lightweight wave brake discs, they are recognised as the measure of all things in terms of application and brake performance. The further refined rear brake cylinder has a new internal mechanism that ensures less wear at the rubber seal and therefore greater durability.
All 2013 KTM EXC models are designed with a lightweight, cast aluminium swingarm featuring direct linkage of the PDS shock absorber on the upper side. The aluminium casting process allows production of a single-piece swingarm with unlimited geometric possibilities and reduces inconsistencies caused by welding work. The swingarm has been designed to provide targeted flexibility on the one hand, thereby bolstering the suspension, and high torsional stiffness on the other.
The SOHC cylinder head is equipped with an overhead camshaft that actuates the titanium intake valves and steel exhaust valves. The whole configuration has been perfectly tuned to the Keihin EFI system for outstanding rideability and performance of the KTM 450 EXC 2013.
EFI / EMS
The engine management system from Keihin with electronic fuel injection and 42 mm throttle body ensures spontaneous, powerful responsiveness and handling, along with maximum performance. Automatic temperature and altitude compensation are state of the art. With an optional map-select switch (PowerParts), a variety of different engine characteristics can be selected.
The slim 9 l tanks are made from lightweight, transparent polyethylene, allowing the fuel level to be seen from the outside. The tried and tested bayonet filler cap can be opened easily with only a quarter turn and features the proven safety mechanism to prevent unintentional twisting.
The high quality KTM wheels with CNC-machined hubs are standard on KTM bikes. They are equipped with new, extremely stable, 7050 aluminium rims from GIANT and the spokes are now furnished with a premium black coating, representing an improvement in terms of corrosion resistance. New MAXXIS FIM tyres - specially developed for KTM - provide excellent traction, very precise directional control and a long service life.
