KTM AND DUCATI

        

The new 250 EXC-F, with further improved performance and new running gear, is once again the main contender for the world championship podium. The most modern four-valve technology ensures massive thrust from the bottom of the range up into the highest speed ranges. Light, extremely agile and a true muscleman in the small class.

CHASSISFRAME
Sturdy, oversized, oval lateral tubes make the chromemoly EXC frame one of the most stable and lightweight designs on the market. Tough lateral plastic frame guards now efficiently protect the high-quality powder coating. The Subframe with broad profiles is made from high-quality aluminium and guarantees optimum stability at minimum weight.

SWINGARM
The ultralight cast aluminium swingarm with directly connected PDS shock absorber ensures optimum flexibility, and hence enormous traction and comfort.

FORKS
The new 48 mm upside-down forks from WP offer new iner and outer tubes for more homogeneous flexibility, a completely new cartridge unit and an optimized bearing seat for the sliding bush. All that, together with a modified seting for improved response, provides significantly greater comfort and greater damping reserves. Adjustable rebound and compression damping as well as the spring preload, the forks with the new star - shaped adjustment knobs for the rebound damping can be adapted even easier to the course and rider.

PDS SHOCK
The overhauled WP PDS shock absorber with stronger PDS nedle and optimised design of the second piston impresses with its more comfortable damping properties. With a variable rebound damping setting and adjustable high-speed and low-speed compression damping, it can be optimally adapted to different course conditions.

BRAKES
KTM and Brembo set the standards when it comes to brakes. Up front, a floating two-piston brake calliper and at the rear, a single-piston brake calliper grip the ultralight wave-shaped brake discs.

COOLING SYSTEM
The integrated cooling system leads from the cylinder head through the frame triangle and via a T-piece straight to the coolers. That means a simplified radiator installation, better air circulation and more space under the fuel tank.

HANDLEBARS
The tapered Neken handlebar of high-quality aluminium has four different positions, so it can be adjusted to fit the rider.

EXHAUST
In conjunction with its cleverly devised inner workings, the design of the aluminium silencer not only looks good; it also ensures optimum performance at a minimum weight and very low sound level.

BODYWORK
The cool bodywork offers optimum ergonomics and a trendsetting appearance. The 2-component technology for the headlight mask, chainguard and front fender ensures both a top quality appearance and optimum rigidity.

FUEL TANK
The tank layout was designed for optimum ergonomics and the best knee contact. The ducts under the spoilers form part of the KTM Airflow system with which fresh air is guided to the airbox via openings in the spoilers.

FUEL TANK CAP
The fuel tank cap with bayonet fitting and new noreturn valve has an additional twist lock, to prevent unintentional opening, that can be easily unlocked by pressing the orange inner segment.

SEAT
A new seat now has an optimised foam core for improved comfort and even longer service life. In addition, the weight was reduced by 150 grams.

REAR FENDER
A lightweight and extremely durable LED taillight is installed in the modern mono-fender, which can withstand even the rigours of competition. An add-on number plate bracket with license number llumination and indicators can be easily removed for sport and competition.

AIR BOX
The large volume ensures a whole lot of power, while the external contours offer you optimum knee contact. The easy, tool-free accessibility to the Twin-Air air filter makes changing the filter child’s play.

SPOILER
The new spoilers reduce the width at the front end by more than 10 mm to enhance ergonomics. The INMOULD technology guarantees optimum durability for the newly integrate d graphics. The spoiler openings at the front serve as air outlets for the coolers and fresh air is drawn into the airbox through the openings at the rear. ENGINEENGINE COVERS
Optimised coating with a new colour and new logo not only looks cool, it also offers improved protection against rocks and rough offroad boots.

VALVE TRAIN
New camshafts with optimised timing ensure better responsiveness and even more power from low revs.

VALVES
In combination with the weight-optimised finger followers, ultra-light titanium valves with new springs and optimised valve guides mean minimum oscillating masses, maximum valve lift and top durability.

GEAR BOX
A strengthened shifting gear for 3rd/4th gear and the optimised idler gear for 3rd gear guarantee increased durability of the gearbox.
