ENGINE

Completely new, the KTM 390 Duke's state-of-the-art, single-cylinder engine once again underlines KTM's development strength. It's clear that the latest materials and production technologies not only deliver the bike's bountiful torque and overwhelming acceleration at all engine speeds, but also good manners in everyday use and outstanding fuel economy. With 375 cc, the single-cylinder engine only weighs 36 kg, thanks to the compact design - typical of KTM - with transmission shafts arranged one above another. Moreover, it delivers a punchy 44 hp with such technical refinements as NaCaSil cylinder coating and forced oil lubrication with performance-boosting casing evacuation (the suction pump not only transfers oil, but also pressure from the crankcase, thereby reducing the running resistance of the crank drive).

CYLINDER HEAD

Just as on the RC8 R, the four valves in the cylinder head of the 390 Duke are actuated by two overhead camshafts and cam levers. This design is not only extremely reliable, but also very durable and almost frictionless thanks to the ultra-hard carbon coating of the cam levers - releasing even more power.

SILENCER

The compact, three-chamber silencer is positioned close to the bike's overall centre of gravity. This aids the centralisation of masses and enhances the playful handling of the 390 Duke 2013. Thanks to a regulated catalytic converter, the emissions are exemplary.

INJECTION

The intricate engine design, state-of-the-art injection electronics and the close-ratio, six-speed transmission not only help the KTM 390 Duke to achieve impressive performance, but also extremely low fuel consumption. Thanks to the regulated catalytic converter, it produces only minimal emissions.

FUEL TANK

The shapely 11 l (12 qt.) fuel tank of the 390 Duke 2013 not only provides the rider with perfect knee contact, but also with a greater range, even when ridden on the edge, thanks to the economic engine.

BRAKES

A state-of-the-art Bosch 9M ABS makes the pleasure of the impressive Duke dynamics even safer and adds the finishing touch to its peerless chassis qualities. The ABS on the KTM 390 Duke monitors the effect of the potent brake system with radially-bolted, four-piston calliper and 300 mm disc diameter - fun with no regrets, developed in close collaboration with the specialists from Bosch and Brembo. And for the stunt riders among us: the ABS can naturally be switched off.

TELESCOPIC FORK

The KTM 390 Duke's high-quality upside-down fork from WP Suspension has the same 43 mm (1.69 in) outer tube diameter as the RC8 R – in other words, real racing equipment that guarantees highest levels of stability and precision.

FRAME

32 kW (43 hp) Power plus an unladen weight of only 139 kg (306 lb.) guarantee tremendous, fleet-footed riding fun with the new 390 Duke. The first-class chassis, with lightweight tubular space frame in the proven KTM design, turns it into a real surfer through the curves. Masses grouped close to the centre of gravity maximise manoeuvrability and precision – and prepare the 390 Duke perfectly for the rush hour slalom.

SWINGARM

The 2013 390 Duke's lightweight, high-quality, pin-jointed, die-cast swingarm is designed and produced according to the same principle as the 690 Duke. The light alloy swingarm with directly linked WP shock absorber excels with extreme torsional stiffness and outstanding tracking stability.

WHEELS AND TYRES

Equally lightweight and delicate as they are stable, the 17 in cast light alloy wheels are fitted with grippy Metzeler tyres - 110 mm (4.33 in) wide at the front and an impressive 150 mm (5.91 in) at the rear. The tyres impress with tremendous grip in both wet and dry conditions, as well as providing supreme durability.
