The KTM 250 EXC-F is as tough as they come, boasting of credentials that practically guarantee top places in a tough and physical enduro sport. Renowned for its powerful performance from deep down up to 13,000 1/min, the new generation 250 EXC-F boasts of an even more powerful DOHC four-stroke engine, a new fuel injection system, a new electric starter, and a completely revamped, top-quality chassis. From top to bottom, the 250 EXC-F is as world-class as it gets, one that’s definitely head and shoulders above its competition.
The 250 EXC-F’s revamped frame is made from high-quality chrome-molybdenum steel and is characterized by even greater lateral stiffness. It also has new wheels that have CNC-machined hubs, Excel rims, and zinc/nickel-coated spokes.
The bike’s overall build is fully complemented by a compact, state-of-the-art 250cc four-stroke engine that excels with a redesigned cylinder head and an improved engine management system with electronic injection. The bike also has a more powerful generator, a redesigned electric starter, and four titanium valves that are actuated in the DOHC cylinder head by carbon-coated cam levers.
Handling is also a critical component of the 250 EXC-F. A new, lighter cast aluminum swingarm accommodates the shock absorber, while a new, 7 mm (0.28 in) longer PDS shock absorber with adjustable rebound and high/low-speed compression damping, as well as a new setting is installed more flatly, provide a comprehensive list of tools that allow this bike to be a world-class machine destined for greatness.

The 250 EXC-F’s compact, state-of-the-art four-stroke engine excels with a redesigned cylinder head, an extremely wide usable rev range and now with even better performance. A state-of-the-art engine management system with electronic injection, a more powerful generator and a redesigned electric starter make the KTM a hard nut to crack for the competition.
The newly developed Keihin engine management system with electronic fuel injection ensures spontaneous responsiveness from the engine. Various engine characteristics can be activated with an optional map select switch.
The completely revamped frame made from high-quality chrome-molybdenum steel is characterized by even greater lateral stiffness. Furthermore, it is even better at absorbing jolts introduced by the suspension system, whereby the playful handling and comfort of the 250 EXC-F have been further optimized.
Chassis and Suspension
The 250 EXC-F’s new, lighter, cast aluminum swingarm accommodates the shock absorber more centrally, in order to load the swing arms more evenly. The new, 7 mm (0.28 in) longer PDS shock absorber with adjustable rebound and high/low-speed compression damping, and a new setting is installed more flatly, so providing even more progression.
The 250 EXC-F is equipped with the latest WP upside-down fork with wider adjustment ranges and a new setting. The sensitive responsiveness and outstanding damping of the open-cartridge fork with 48 mm (1.89 in) outer tubes are a perfect complement for the 250 EXC-F’s playful handling and precision.
The 250 EXC-F’s new bodywork with the very slim seat and spoiler lines, plus excellent contact points, perfects the bike’s ergonomics, making handling even simpler and more precise. The longer rear fender protects the rider even more effectively from swirled up stones.
The 250 EXC-F is equipped with both a kickstarter and an electric starter. The redesigned drive for the electric starter is now integrated into the generator cover instead of the engine case, so the bike can be converted into a pure kickstarter simply by replacing the generator cover.

Edmondson----"The new front fork bushes and seals with revised settings have made it much more accommodating over the small bumps and loose stones. For the "short in the leg", they will look to the low seat option from the Power Parts collection of goodies. Here you really do have 2 bikes in one for those that dream a lot of bieng better than the bike they ride!"
