Overview
Who, in 2007, could claim to rival the BMW R 1200 GS in the large-displacement adventure segment without merely playing a bit part? KTM, of course. With the 990 Adventure S, the Austrian manufacturer didn't just offer an alternative. It laid down a compelling argument — one of weight, or rather lightness: 199 kg dry, where the Bavarian tipped the scales a good twenty kilos heavier. That's no minor detail when you're talking about machines meant to leave the tarmac.

Beneath the chromoly tubular frame, the 999 cc LC8 twin delivers 98 horsepower at 8,500 rpm and, more importantly, 95 Nm of torque from just 6,500 rpm. This engine is a familiar unit — essentially the Super Duke's, lightly recalibrated for adventure duty. It pulls hard, vibrates a little, and has real character. Throttle response is direct, sometimes even a touch abrupt in first and second gear. The six-speed gearbox and chain final drive betray KTM's philosophy: performance first, comfort second. Choosing chain over shaft is a deliberate trade-off. Less weight, more maintenance hassle. Where you draw the line is up to you.
The chassis was a cut above what the Japanese competition offered at the time. The WP suspension — inverted fork up front and PDS mono-shock with hydraulic preload adjustment at the rear — provides generous travel and composed behavior on rough tracks. Ground clearance of 316 mm allows passages that few adventure bikes of this displacement can tackle without a second thought. The 21-inch front and 18-inch rear wheels confirm the genuine off-road intent. This is a far cry from a road-biased trail bike in disguise. On the other hand, the 915 mm seat height will naturally thin the ranks. Below five foot nine, you'd better plan on thick-soled boots or a trip to a specialist for a shaved seat.

The 22-liter tank allows for reasonable range between stops, even though the Austrian twin proves thirstier than a German boxer when you crack the throttle hard. The claimed top speed of 210 km/h is largely irrelevant on this type of machine, but it speaks to the engine's potential. On the motorway, the KTM 990 Adventure S holds its own, even if wind protection remains lacking compared to a Triumph Tiger 1050, for instance. Braking, handled by twin discs up front and a single at the rear, proves effective without being quite as sharp as you'd expect from a machine wearing the Ready to Race badge.

At €12,990 when new, the price tag was steep but justified by above-average standard equipment and genuine off-road capability — not the kind merely suggested by a sticker on the tank. The 990 Adventure S was aimed at demanding globetrotters, the kind who want a machine capable of crossing Morocco and then riding home on the motorway without switching bikes. Not a beginner's adventure bike, not a pure enduro either. A purpose-built touring tool for those who refuse to choose between dirt and asphalt, with that extra dose of character only an Austrian twin can deliver.
