500 EXC 2013 - OVERVIEW
For all those who are forever seeking a little bit more. Perfectly controllable power in extravagant proportions, low weight and an unsurpassed chassis characterise an enduro of remarkable versatility: a sensational fighting machine and absolutely reliable workhorse rolled into one, the indisputable benchmark in terms of weight and rideability - the KTM 500 EXC.
All EXC models are fitted with a PDS shock absorber and 48 mm USD front fork made by WP Suspension. New fork oil provides better sensitivity and more constant damping characteristics. The wide range of adjustability is KTM standard.
Following the proven KTM tradition, the frames are made of high-quality, lightweight chromemoly steel material in various profiles. They are specifically designed in conjunction with the PDS rear suspension system to provide precise cornering and high track stability.
SWING ARM »
All models feature a light-weight cast aluminium swing arm designed to fit the PDS shock absorber. The design guarantees high torsional rigidity and optimal flex characteristics, supporting the suspension.
The high-quality wheels with CNC machined hubs and high-strength 7050 aluminium GIANT rims are assembled in Mattighofen. The new spokes are covered with noble black coating which improves the corrosion resistance. Especially developed for KTM, are the new MAXXIS FIM tyres (80/100-21" MAXX CROSS 7311, 120/90-18" & 140/80-18" MAXX ENDURO 7314) which provide excellent traction, very precise cornering and top durability.
FUEL TANKS »
The slim 9.5 litre fuel tanks are made from lightweight translucent polyethylene. The 4-strokes are fitted with an additional micro-screen which is now located in the fuel line connector between the injector and tank for easier access. 13 litre tanks available for all models from the PowerParts collection, for the 2-strokes an additional 10 litre version.
The design of the airbox secures best protection for the TWIN AIR filter against dirt and maximum airflow for best performance. The ability to change the large filter quickly and without tools is the KTM standard.
EXHAUST SILENCER »
All bikes are fitted with lightweight aluminium silencers, which reduce the noise level to the FIM noise emission regulations (112 dB(A)).
The proven Brembo brake system is combined with lightweight wave discs for optimal brake performance. A further developed rear master cylinder features a new internal design providing less wear of the seal rubber and therefore longer durability.
To make a bodywork with super slim ergonomics and excellent contact points between rider and machine was a major development target. It provides unlimited freedom of movement. Newly designed graphics give a new appearance to the bikes.
All models are fitted with tapered high-strength aluminium handlebars made by Neken. For model year 2013 new 2-compound grips with KTM branding provide an excellent shape and improved grip.
The 450 and 500 EXC models are without a doubt the benchmark in their classes. The SOHC engines (449.3 and 510.4 cc) feature an extremely compact design, easy maintenance and an excellent durability at a minimal weight. Together with the Keihin EFI system, they provide unrivalled enduro specific performance and rideability.
CYLINDER HEAD »
The SOHC cylinder head is fitted with titanium intake and steel exhaust valves activated by a single cam. The entire configuration is developed to best suit the EFI system for outstanding power delivery and performance.
CRANK SHAFT »
The crankshaft at 72mm for the 500 EXC is equipped with an ultra-light PANKL connecting rod which guarantees the highest precision and reliability.
DDS CLUTCH »
The engine of the 450/500 EXC is equipped with the KTM DDS clutch (Damped Diaphragm Steel) with a steel basket and a diaphragm spring in conjunction with a Brembo hydraulic system.
BALANCER SHAFT »
Due to the sophisticated design, KTM engineers managed to mount a small, laterally located counter balancer, which is also designed to hold the water pump wheel.
The engine is fitted with a reliable and light-weight electric starter plus kickstarter. The electric starter drive features reduced weight for MY2013.
