KTM 500 EXC 6 days 2015 — Specifications

Six days. A thousand kilometres of dirt, mud, and rocks. Forty hours in the saddle under conditions that would bring any ordinary machine to its knees. The International Six Days Enduro is the most brutal enduro competition on the world calendar, and KTM has never shown up there as a casual visitor.

The 2015 500 EXC Six Days is the Austrian manufacturer's direct answer to this test of truth. Beneath the 9-litre tank beats a 510.4 cc single-cylinder four-stroke producing 58 horsepower. That's a lot for 111.5 kg dry. This power-to-weight ratio places this machine in a category where few competitors dare venture: the Husqvarna FE 501, technically close as it comes from the same group, is its most serious rival, but it arrives after KTM on this historic ground.

The chromoly steel tubular frame absorbs impacts with controlled rigidity, without being brutal in weight transfers. The WP suspension does serious work: a 48 mm inverted fork with 300 mm of travel up front, a monoshock swallowing 335 mm of compression at the rear. For committed enduro riding, these figures are far from trivial. The 970 mm seat height demands a certain stature — this is not a machine for everyone physically, and that's a deliberate choice. This KTM targets the experienced rider, one who rides regularly and is looking for a competitive foundation without starting from scratch in terms of preparation.

The 6-speed gearbox proves an asset in competition where terrain changes character from one special stage to the next. The 11.8:1 compression ratio, combined with bore dimensions of 95 x 72 mm and four-valve timing, defines an engine that prioritises output across a broad range rather than brutal peaks. For the long, gruelling days that define the Six Days' reputation, this progressive delivery matters as much as raw power. Braking with a 260 mm disc up front and 220 mm at the rear delivers clean stops without drama.

At €10,195, the price tag is consistent with the level of equipment delivered as standard. The Six Days version justifies its cost through specific components that make the difference when sustained competition is on the agenda. Compare this price to an equivalent build on a standard base and the gap closes quickly. For those who have followed the range's evolution, including through to the KTM 500 EXC 6 Days 2019 which carries this philosophy forward with refinements, the 2015 model year remains a benchmark in the lineage. This is not a Sunday afternoon ride. It is a tool designed for competition, ready to be taken to terrain anywhere in the world without the factory having any reason to blush.
