In KTM’s ongoing quest to construct extra highly effective bikes and design weirder headlights, the Austrian powerhouse has simply yanked the covers off the brand new KTM 1390 Tremendous Duke R and 1390 Tremendous Duke R Evo. The information comes virtually with out warning—until in fact you learn the tea leaves, and acknowledged the discharge of the brand new KTM 990 Duke at EICMA as a precursor to a redesign of KTM’s flagship bare streetfighter.
The brand new KTM 1390 Tremendous Duke R celebrates the Duke sequence’ upcoming thirtieth birthday with extra energy, higher suspension, and a smorgasbord of refined refinements. It seems angrier and wilder than ever too, adopting lots of the aesthetic tweaks seen on the 990 Duke. KTM 1390 Tremendous Duke R Evo goes a step additional, with electronically managed semi-active suspension.
The Tremendous Duke’s new 1390 designation signifies a capability bump for its already punchy V-twin engine. KTM elevated its bore from 108 mm to 110 mm, pushing the displacement to 1,350 cc. That makes it good for 10 extra horses and 5 Nm extra torque than earlier than, bringing its output to 190 hp at 10,000 rpm and 145 Nm at 8,000 rpm.
The up to date mill additionally sports activities a variable valve elevate system through a shifting cam that behaves in accordance with the place within the rev vary you’re. In line with KTM, it’s there to make sure optimum energy and torque all through the entire vary, with variable gasoline mapping to satisfy Europe’s ever-tightening emissions requirements. The Tremendous Duke additionally includes a redesigned airbox and ram air system, new throttle our bodies, and a repositioned top-feed injector that guarantees smoother energy supply.
We’ve ridden the outgoing Tremendous Duke, and, whereas it’s no slouch, it’s additionally remarkably manageable. If we’re being sincere, its motor didn’t want an replace—but when the modifications to the 1390 are nearly as good as marketed, it’ll be primed for peak shenanigans. Revised gearing at fifth and sixth gear ought to make it much more of a blast at high velocity, too.
The Tremendous Duke’s chassis hasn’t modified a lot, nevertheless it’s been augmented with new suspension elements. 48 mm WP APEX open cartridge forks prop up the entrance, adjustable for compression, rebound, and preload. Out again, a WP APEX piggyback shock splits its compression adjustment into high- and low-speed adjusters.
The Tremendous Duke EVO takes all that and provides the newest model of WP’s ‘Semi-Energetic Know-how’ system. It’s an electronically-controlled variable damping system that adapts in real-time, primarily based in your driving model and the highway floor. There are 5 damping modes, selectable from the Tremendous Duke’s TFT show.
An additional ‘Suspension Professional’ pack is accessible ex-factory, which incorporates further ‘Professional’ and ‘Observe’ suspension settings. It provides the flexibility to set suspension preload electronically in accordance with your top with three base settings, and it consists of an anti-dive setting. Then there’s the ‘Manufacturing facility Begin’ characteristic, which routinely lowers the rear wheel at a standstill for extra traction off the road; not in contrast to the beginning methods utilized in MotoGP.
Stopping energy comes from twin four-piston Brembo Stylema monobloc calipers up entrance, gripping 320 mm discs. A 240 mm disc sits out again. A brand new Brembo grasp cylinder provides extra adjustment than earlier than, whereas a self-venting system signifies that the clutch and brake grasp cylinders don’t require common bleeding.
Digital aids embody a number of driving modes, ABS, traction management, and elective extras like anti-wheelie management and launch management. The elective observe mode comes with two show settings for the bike’s TFT display, as a way to select to focus both in your lap occasions or telemetry information.
The KTM 1390 Tremendous Duke R has undergone various visible modifications too, beginning with its headlight. Taking the normal alien-like Duke headlight design to new heights, the deeply recessed LED unit follows the identical strains because the 990 Duke’s new mild. The setup is break up into daytime operating lights and a ‘common’ headlight, with sensors that alter the LED depth in accordance with ambient lighting circumstances.
A brand new 17-liter [4.6-gallon] gasoline tank sits up high, flanked by sharper shrouds that echo the geometry of the headlight. Out again, the tail part has been trimmed right down to the extent that it’s shed its taillight; taillight duties at the moment are dealt with by the rear mixture flip sign LEDs. The rider geometry is barely sharper too, due to a refined repositioning of the tank and handlebars.
Like its predecessor, the Tremendous Duke is compact, angular, and lean. But it surely’s significantly extra aggressive-looking now, with a spec sheet to match. Bare streetfighters may not be our traditional fare, however we will’t wait to swing a leg over it.
