KTM 250 EXC-F 2015: Handling Miracle

The 250 EXC-F has been an established force in the E1 World Championship for years now and last year it bore Meo Antoine to the world title. Completely revamped for the last model year with a new engine and new bodywork, the enduro receives several clever detailed enhancements in MY 2015 to ensure its superiority in future as well.

2015 KTM 250 EXC-F Key Features:

Wheels and Brake:

The wheels are equipped with new, black, 7050 T6 aluminium Giant rims, black coated spokes with lightweight aluminium nipples and lightweight CNC-machined hubs, allowing highest levels of stability to be achieved while keeping weight to a minimum. The fitted Maxxis enduro tyres have been specially developed for KTM and excel with perfect traction and outstanding performance.

High-tech brakes from Brembo have always been standard equipment on KTM offroad bikes and, together with the lightweight wave brake discs, they are the measure of all things in terms of brake technology. As the best brakes in enduro sport, they remain unchanged for MY 2015.

New Engine
The 250 EXC-F is a proven winner in the fiercely fought enduro series and enjoys the recognition of several prestigious world championship titles. This machine shares many basic components with the successful engine of the 350 EXC-F and excels with first-class performance and plenty of torque from the bottom end up, thanks to its advanced design and state-of-the-art fuel injection. The bike is manoeuvrable, agile and controllable, quickly gaining the complete trust of the rider. The DDS clutch features Brembo hydraulics for comfortable clutch operation, while an electric starter and a kickstarter make starting no problem in every situation. Newly developed oil strainer sealing rings are used for MY 2015 to provide better durability in the most extreme conditions and a longer service life.

The crankshaft of the 250 EXC-F is designed with sufficient gyrating mass for spontaneous throttle response and best possible traction. A plain bearing in the lower conrod eye with two press-fit bearing shells that run directly on the crank pin, increases the longevity of the engine and extends the crankshaft service intervals - two major benefits for the customer.

Engine Case
Thanks to the crankcase being manufactured in a pressure die-casting process, it has been possible to significantly reduce the wall thicknesses compared with a gravity die-cast case. A high-strength aluminium alloy is used, which is extremely resistant to stone impact and other damage.

Cylinder Head
The heart of KTM EXC DOHC engine is the cylinder head with twin overhead camshafts and ultra-light, DLC-coated cam followers. In conjunction with the large intake valves, the big, flow-optimised ports enable optimum intake gas flow for outstanding performance. The camshafts have been specially designed to maximise performance and torque, with power development adapted to enduro riding. The engine is equipped with ultra-light titanium valves and cam followers for reduced reciprocating weight to allow higher revs.

Balancer Shaft
To counterbalance the inertia forces, the 250 EXC-F engine is equipped with a balancer shaft that acts as a multi-function shaft, driving timing chain and water pump simultaneously.

The 250 EXC-F engine offers the benefits of en electric starter and a kickstarter. Positioned behind the cylinder, the electric starter is well protected and connected via the electric starter drive in the ignition cover to the starter freewheel on the ignition rotor.

DDS Clutch
For MY 2015, the DDS clutch (Damped Diaphragm Steel) is equipped with a further refined, lighter, single-piece basket, which together with its integrated primary gear, is machined from a single solid billet of high-strength steel. This process guarantees unbeatable reliability and allows the engine to be extremely narrow thanks to the compact, rivetless design of the outer clutch hub. In addition, this design allows use of thin steel discs, which also contributes to the compact dimensions of the clutch. The diaphragm spring enables implementation of an additional hub damping mechanism - a benefit in terms of traction and gearbox wear. Finally, in conjunction with the diaphragm spring, the hydraulic clutch actuation system from Brembo ensures very smooth and very precise clutch control.

Compared with its predecessor, the new 6-speed enduro gearbox, developed especially for the 250 EXC-F, has slightly shorter transmission ratios for 4th, 5th and 6th gears. The new gearbox excels with high precision and easy shifting. The secondary transmission has also been adapted to the new gearbox.

Engine Management System (EMS)
The engine management system (EMS) from Keihin, with electronic fuel injection and 42 mm throttle body, ensures spontaneous responsiveness and maximum engine performance. An oil-cooled, 196 W alternator provides sufficient power for the fuel injection system, lights and other electrical loads. A redesigned ECU ensures even faster and absolutely reliable data processing. Various engine characteristics can be selected via the EMS, with a map-select switch available as a PowerPart. Furthermore, a user-setting tool (also available as an option) allows data to be read from the bike by laptop and the mapping, ignition and fuel injection to be modified in a matter of a few mouse clicks.

The bodywork has been designed ergonomically and functionally in such a way that the whole motorcycle is in perfect harmony with the rider down to the very last detail.

At the same time, the ingenious design of the airbox guarantees optimum protection of the air filter from dirt plus maximum air throughput for the highest performance. The airbox covers are manufactured in a 2-component process with new in-mould graphics. The filter is replaced very quickly, without any tools. Furthermore, two additional tabs on the cover allow it to be secured with bolts if desired.

All EXC models are equipped with an extremely sturdy, tapered Neken handlebar made from high-strength aluminium alloy. In accordance with the proven KTM standard, the black anodised handlebar can be fixed in a choice of four positions. The handguards are made from a new material in MY 2015 in order to achieve even greater impact resistance.

The new speedo from MAE integrates all control lights, except those for the turn indicators, into a single component. This provides the cockpit with a cleaner and tidier appearance and makes the available information clear and easy to read.

Superior Chassis:

The modern frame design of the 250 EXC-F, comprising lightweight, high strength, chrome-molybdenum steel section tubes, combines maximum longitudinal stiffness with optimum torsional stiffness. It guarantees easy handling and precise steering behaviour, as well as excellent ride stability. So the new frame not only shines with the new colour, it also clearly represents the benchmark in terms of weight and stability. The frame colour shines in MY 2015 in the same orange as the KTM factory racing team, making the styling even more attractive. Moreover, it’s easier to maintain and provides more space for mounting the fuel tank and other components. Thanks to the frame design and in conjunction with the rear PDS damping system, shocks at the rear wheel are absorbed and dissipated optimally.

The cast aluminium swingarm has been developed with state-of-the-art calculation and simulation software and constructed, in terms of design and wall thickness, for minimum weight with optimum stiffness and precisely defined flexibility.

The KTM 250 EXC-F has its own individual suspension setting, optimally tuned to weight and engine. The high-quality WP suspension components have been specially designed for enduro use. They ensure maximum traction and plenty of comfort. At the rear, a PDS shock absorber from WP Suspension works with a direct linkage to the upper side of the swingarm. The wide range of setting options for rebound damping and high- and low-speed compression damping are standard on KTM bikes.

Triple Clamps
The triple clamps have been specifically designed for enduro use and ensure precise handling thanks to their supporting of the fork flex. The rider receives precise feedback from the front wheel, even in the toughest terrain, thereby increasing riding safety and speed.
