KTM 250 EXC-F Six Days Features and Benefits

WITH EXCLUSIVE OPTIONAL EQUIPMENT

SIX DAYS EQUIPMENT

• Map select switch on the handlebars for selecting different engine management mappings

• Camel SXS seat for improved long-distance comfort

• Engine guard made of high-strength plastic for protecting engine case and frame down tubes

• Radiator fan for optimising temperature control under extreme loads

• CNC-machined, orange-anodised triple clamps for high-precision clamping of the fork tubes in favor of optimum sliding of the telescopic fork

• Knock-out wheel spindle for easier removal of the front wheel

• Full brake disc at the rear for improved heat resistance and therefore reduced pad wear

• Rear brake disc protector for protecting the brake disc from mechanical damage

• Quick-change brake pad securing bolts at the rear for quicker changing of brake pads without tools

• Aluminum rear sprocket with riveted-on steel ring gear for a combination of reduced weight and increased durability

• Wheels with black-anodised, extremely robust Giant rims and spokes with a high-quality, black tin-nickel coating

• The same design as the KTM factory bikes thanks to Six Days graphics, orange powder-coated frame, orange anodised triple clamps, orange anodised handlebars and anthracite anodised silencer

NOW EVEN MORE ERGONOMIC

BODYWORK

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.

OPTIMISED ELECTRIC STARTER

ELECTRIC STARTER

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.

NOW WITH AN EVEN MORE SUPERIOR CHASSIS

NEW FRAME

The completely revamped frame made from high-quality chrome-molybdenum steel is characterised 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.

NEW SWINGARM, NEW PDS, NEW SETTING

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.

TELESCOPIC FORK, NEW SETTING

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.

NEW WHEELS

Practically unbeatable in terms of weight and stability, the new wheels have CNC-machined hubs, new black-anodised rims from Giant, black zinc/nickel-coated spokes and ultra-light aluminum nipples. They reduce the unsprung and gyroscopic masses, hence boosting the playful handling of the 250 EXC-F.

NOW WITH EVEN MORE PERFORMANCE ENGINE

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.

VALVE TRAIN AND NEW INTAKE PORT

Four titanium valves are actuated in the DOHC cylinder head by carbon-coated cam levers. The 250 EXC-F's elaborate valve train and engine with an extremely short stroke facilitate speeds of up to 13,000 1/min. The further developed intake port now allows 10 % greater gas flow.

NEW EFI/EMS

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.

NEW SILENCER

The 250 EXC-F's new, improved silencer not only offers greater volume and a new design featuring a special Six Days coating, it also reduces noise levels to the stricter standards of the future
