2012 KTM 250 EXC-F Six Days

The International Six Days Enduro is considered the world’s largest enduro competition and when you’re gearing up for a race that involves over a thousand off road kilometers, you’re going to need the best equipment in the market to go to battle with.

For KTM , the list of bikes that fit this bill runs long, but one of them is the 250 EXC-F Six Days.

In terms of design, the 250 EXC-F Six Days has new bodywork that features a very slim seat and spoiler lines, plus excellent contact points, making for an ideally ergonomic ride. It can take the rigors of enduro racing without even skipping a beat, thus making handling even simpler and more precise. Practically unbeatable in terms of weight and stability, the new wheels have CNC-machined hubs, new black-anodized rims from Giant, and black zinc/nickel-coated spokes. They reduce the unsprung and gyroscopic masses, hence boosting the playful handling of the 250 EXC-F Six Days.

As for the engine, the 250 EXC-F Six Days’ 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. Likewise, a state-of-the-art engine management system with electronic injection, a more powerful generator, and a redesigned electric starter makes the 250 EXC-F Six Days a true contender in the ever-competitive world of enduro racing.

If handling is your thing, you’ll be pleased to know that the 250 EXC-F Six Days comes 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.

Engine

KTM 250 EXC-F Six Days

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.

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.

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 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.

New Frame and Suspension

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.

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.

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.

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.
