The KTM 125 EXC Six Days was especially developed for the famous enduro competition the International Six Days Enduro.

The motorcycle’s backbone is represented by a modern frame comprising lightweight, high strength, chrome-molybdenum steel section tubes. The frame houses a 124.8 cc, 1 - cylinder, 2 - stroke, water - cooled, engine with reed intake and exhaust control. It is also worthy of being mentioned that for 2015, the engine receives new carburettor tuning. Its power is transferred to the ground by means of a 6 speed claw shifted transmission.

The bike’s speed is kept in leash by a set of high-tech brakes from Brembo which include a new floating front brake disc and a solid rear brake disc. There is also a new front brake disc guard for the MY 2015.

For The Toughest Missions

The 125 EXC Six Days is "READY TO RACE " for the world’s largest enduro competition, the "International Six Days Enduro". Six days in succession, over a thousand offroad kilometres, 40 hours in the saddle - a gruelling test, not only for the rider. A whole package of high-quality special options makes the KTM 125 EXC Six Days fit for this ruthless contest, in which more than half the starters bank on KTM every year. No other brand is anywhere near as strong and successful in offroad sport. In 2013 the fastest rider overall was once again on a KTM. The Six Days will take place in Argentina in 2014 and the KTM model range has been updated accordingly to be equipped for everything that the South American terrain has to offer. In the form of the new Six Days models, KTM offers well-proven, robust machines that fully satisfy the high demands of this extraordinarily tough competition.

2015 KTM 125 EXC Six Days Key features:

Superior Chassis:

Individual Suspension Setting
Each EXC model has its own individual suspension settings, optimally tuned to weight and engine. At the rear, a PDS shock absorber from WP Suspension works with a direct linkage to the upper side of the swingarm. The PDS shock absorber has been updated with a new Monoseal gasket for MY 2015, for improved sealing and easier maintenance. The wide range of setting options for rebound damping and high- and low-speed compression damping are standard on KTM bikes.

Telescopic Fork
The KTM Six Days models are equipped with a 48 mm 4CS closed-cartridge fork from WP Suspension. The 4-chamber technology (4CS) patented by WP not only provides a key benefit in terms of responsiveness and consistent damping characteristics, it is also lighter and oil services prove to be far simpler than on the conventional closed-cartridge versions. Naturally, the setting can easily be adapted to track and rider in a matter of a few clicks at the top of the fork: compression damping on the left-hand shaft, rebound damping on the right - another advantage of the 4CS technology.

The modern frame design of the 125 EXC Six Days, 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. The frame clearly represents the benchmark in terms of weight and stability.

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.

Triple Clamp
Meticulously finished triple clamps, machined from a solid block: Not only do they look classy in anodised orange; they are also designed in such a way that they support the responsiveness and sliding behaviour of the new fork with their special shaping.

High Quality Wheels
The high-quality alloy wheels from GIANT made of extremely stable 7050 aluminium, featuring exclusive Six Days lettering and CNC-machined hubs, are standard on all KTM Six Days models. Developed in cooperation with KTM, the Metzeler tyres provide excellent traction, very precise directional control and a long service life. An additional Six Days standard feature: the Supersprox 2-piece rear sprocket with steel outer ring and aluminium star.

High-tech brakes from Brembo have always been standard equipment on KTM offroad bikes and, together with the floating front brake disc new for 2015 and the solid rear brake disc, they are the measure of all things in terms of brake technology. The new front brake disc guard ensures that it stays this way.

The KTM 125 EXC Six Days has bodywork with extremely slim ergonomics and excellent contact points between rider and machine. It provides unlimited freedom of movement. For MY 2015, the bike excels again with the graphics restyled in 2014 in the colours of the ISDE in Argentina.

The 125 EXC Six Days is equipped with a tapered Neken handlebar made from high-strength aluminium alloy. In accordance with the proven KTM standard, the 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.
