KTM's assault on European motorcycle manufacturing supremacy is being led into battle by a quartet of new-age warriors including the dual-purpose 990 Adventure that's back for another tour, the all-new 950 Supermoto, a single-cylinder 690 Supermoto and the undisputed commander of the Orange Army, the striking 990 Super Duke.
The LC8 engine format of 999cc, dohc eight-valve V-twin, with cylinder spaced at 75 degrees, is retained along with most components. But the combustion chambers have been reshaped, valve timing is new, the spark plugs have been repositioned, and the plugs themselves are new. The injection system has also been revised, as has the exhaust system with its catalyser-holding, Euro3-meeting pair of under-seat silencers.
Although the basic chassis layout remains, the chrome-moly tubular steel frame is modified to give a slightly shallower steering angle, while new fork yokes mean trail is unchanged. Suspension is by multi-adjustable WP units, as before, with the 48mm usd forks and cantilever monoshock both getting slightly firmer springs. Brembo supplies new 17-inch wheels plus radial four-pot, four-pad calipers to grip the 320mm front discs.
The KTM ‘Hard Parts’ catalogue is packed with extras for the KTM 990 Super Duke like Akrapovic race exhausts, crash bobbins, luggage and carbon-fibre bodywork.
