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.
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.
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.
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 250 EXC is equipped with both kick and electric starters. This simplifies starting the bike in all situations. With its patented placement in a longitudinal direction above the ignition, the compact starter system is optimally protected and provides a decisive advantage in hard offroad use.
New cylinder head design with optimised combustion chamber for a smoother power delivery.
The 6-speed transmission, specially graduated for enduro use, makes the 250 EXC particularly agile in the toughest terrain.
By opening and closing a plug connection, the choice can be made between the standard ignition curve and a softer version. Those who prefer even greater convenience can buy a switch from the PowerParts range.
