The 1390 is at the top of the food chain in the Duke lineup, and KTM describes the new variant as a "new beast on the prowl," and the most fearsome iteration of the model yet. Judging by the changes we know were made to the thing, we're inclined to believe that description is not that far from the truth.
The modifications made to the bike go beyond the usual visual upgrades one gets whenever an existing bike is renewed. Sure, KTM did that, too, but the scope of the modifications goes well beyond that and touches pretty much everything, from the way the bikes look to the way they perform.
That means the engine was altered as well. Sure, the LC8 engine is still in the frame, but thanks to a bore increase to 110 mm the displacement was taken to 1,350cc. Fitted with an all-new cam shift, now integrated on the cylinder heads, the engine develops a massive 190 horsepower at a perfectly round 10,000 rpm, and 145 Nm of torque at a lower value, just 8,000 rpm.
An important upgrade made to the range has to do with the riding modes - two new settings have been added, Performance and Track. They come with lap timer and telemetry stats. On top of that, KTM now offers an optional engine brake control system for the bike.
The tank is not there solely to be the place where the fuel is stored, but it "also performs an important ergonomic" and aerodynamic function. What KTM means by that is that it features spoilers and winglets that contribute to the bike's increased downforce. It's also 700 grams lighter than before, thanks to the fact that "every panel has been calculated for optimum thickness and minimized where possible."
The bike is supported by a new WP Apex shock at the rear, which is fully adjustable, and a new 48 mm open cartridge fork at the front. The wheels of both 1390 motorcycles wear Michelin Power GP tires.
One of the things that sets the regular two-wheeler apart from its EVO sibling is the suspension management system. On the EVO it comes as the WP Semi-Active Technology, meaning it has electronically controlled magnetic valves for variable damping.
KTM focused on completely revising the lighting system on the 1390 Super Duke R. At the front the bike is fitted an all-new LED headlight which holds on its profile the position and daytime running lights. The headlight comes with a follow me home functionality, but more importantly than that, it adapts its intensity depending on ambient light conditions. A sensor included in the bike's dashboard helps with that.
On the visual front the new Super Duke comes with a redesigned air intake and airbox and a lower overall profile. The paint jobs that will be available for it will be select 30 Years of Duke ones, meant to be reminiscent of the orange scheme found on the 2005 KTM 990 Super Duke.
The bike maker did now say when the new 1390 Super Duke R and its EVO sibling will become available, but it already has them listed on its configurator. Pricing at the time of writing is not known.
An important thing to mention is that KTM plans to give one of these babies away, at an undisclosed time in the future, but definitely before the end of the year. All one has to do to get their hands on a brand new Austrian naked is sign up for the company's newsletter. A draw will be held to determine the winner.
