Overview
Six days. A thousand kilometers of tracks, mud, rocks and forests. Forty hours in the saddle, managing both the controls and your nerves. The ISDE, the International Six Days Enduro, is the absolute benchmark of world enduro, the thermometer that never lies. And for years, KTM has dominated it with a regularity that makes the other manufacturers look like mere spectators.

This 2015 350 EXC-F Six Days is the direct expression of that competition heritage. On the scales, it weighs in at 107 kg dry, which places it firmly in the category of machines built for efficiency, not showmanship. Its single-cylinder 349.70 cc engine produces 45 horsepower with a compression ratio of 12.3:1 and a short but wide bore, 88 x 57.5 mm, that favors low-rpm response over high-rev horsepower. It's a coherent choice for enduro use, where torque management takes priority over impressive figures on a spec sheet. The six-speed gearbox delivers clean shifts, and with 9 liters in the tank, the range remains reasonable for tightly drawn special stages.
The technical specification speaks for itself. The 48 mm WP inverted fork with 300 mm of travel and the WP monoshock with 335 mm of stroke form a duo calibrated to absorb hostile terrain without wearing out the rider prematurely. The brakes — a 260 mm front disc with a twin-piston caliper and a 220 mm rear — provide sufficient bite across variable surfaces. The seat height of 970 mm is tall, very tall, and effectively rules out shorter riders. This is not a machine for beginners; it's a machine for those who already know what they're doing in the dirt.
The chrome-molybdenum steel tubular frame ensures structural rigidity without adding weight, and the 80/100-21 front and 140/80-18 rear tires match competition enduro standards. The price of €9,900 places this Six Days a step above the standard versions, but the premium is justified by a factory preparation designed for real competition use. Compared to a Husqvarna FE 350 or a Beta RR 350, the KTM plays the card of sporting legitimacy and an exceptionally well-stocked OEM parts network. That is its true competitive advantage, beyond the technical data alone.
This machine is not aimed at Sunday leisure riders. It targets the serious rider, committed to competition or wanting to ride equipment that isn't afraid of the terrain. The Six Days name is not hollow marketing — it's a promise of robustness verified under the most demanding conditions imaginable.
