The advanced design wind shield in combination with the aerodynamic optimized motorcycle front ensures incredible wind protection for rider’s chest and arms.

The two-part seat offers first class supersport ergonomics with perfect support for rider and pillion. With a seat height of 820mm it enables the rider to have a secure stance while also being high enough for sporty use and real big-bike feeling.

Fuel Tank
A brand new steel fuel tank with 10l capacity (including 1,5l reserve) has been developed for the RC, perfectly matching the supersport style and vehicle design, together with rider ergonomics. Thanks to the economic engine the RC achieves impressive efficiency even when ridden hard for a considerable distance.

Handle Bar
Brand new clip on handlebars and switches contributes to a sporty and aggressive riding position combined with advanced control.

Outstanding Style:

Thin Tail
Fitting perfectly into the pure racing look, the number plate holder rounds KTM’s high performance bike off.

The brand new bodywork, footrests and pedals not only provide a unique supersport look but also help the RC to master extreme cornering by allowing a greater leaning angle.

Integrated Blinkers
As a special feature the RC incorporates blinkers into mirrors structure, which not just looks very sporty but also contributes to the perfect aerodynamics.

Brand new twin headlight opens a new direction for KTM style and perfectly matches with the racing supersport look of the RC.

Racing DNA:

The state-of-the-art, liquid cooled, single-cylinder, four-stroke 375ccm engine with twin overhead camshafts, four valves and electronic fuel injection, already equipped in the Duke 390 provides outstanding power and thanks to the balancer shaft, delivers the highest level of smoothness. Because of the KTM-typical compact design with stacked transmission shafts the engine has an unbelievable low weight of 36kg. Combine that with technical details like a forged piston, Nikasil-cylinder-coating and forced feed lubrication with power-promoting body-evacuation and you get an engine which provides a remarkable 44hp. The engine is equipped with an electric starter powered by a 12V/6Ah battery.

Triple Clamps
The brand new forged aluminum triple clamps are eye-catchers and together with the clip on handlebars guarantee a pure supersport racing feeling.

Pillion Ride Seat
In order to make no compromises in terms of supersport look the KTM engineers integrated the pillion seat into the bodywork lines so that it looks like a real racing bike tail, but ensuring excellent comfort for the passenger.

KTM developed in cooperation with Brembo a powerful and easy to control brake-system which allows the rider to be always in control of the RC. A four piston radially bolted caliper in combination with a single brake disk (300mm diameter) in the front and a single piston floating caliper with a single brake disk (230mm diameter) for the rear wheel guarantee excellent braking response even under the most extreme conditions.

Telescopic Fork
The KTM RC 390 high-quality upside-down fork from WP Suspension has the same 43 mm outer tube diameter as the RC8 R – in other words: real racing equipment that guarantees highest levels of stability and precision.

Visually similar to the lightweight and approved Duke steel trellis frame, the orange painted frame has been modified to better fit the supersport ergonomics and dynamics. The increase of the steering head angle to 66,5 degrees results in a shorter trail, shorter wheelbase and increased ground clearance. All these modifications release the complete racing potential of the RC and guarantee quick, agile and playful handling.

The 100% digital LCD display has everything you could expect from a state of the art KTM motorcycle, including engaged gear, fuel gauge and service reminder information. Just like supersport racing machines an RPM alert indicates when is the best moment for shifting up.

Swing Arm
The light alloy swingarm with directly linked WP shock absorber excels by providing extreme torsional stiffness and outstanding tracking stability.

“RC390 will be hitting dealership floors in December, but pricing is yet to be announced. As expected the RC will cost more than its 300cc Japanese rivals, and KTM sources can only hint at a mid-$6000 price range. But there is a solid case to be made for the RC390 being worth the extra chunk of change. For one, just look at it. The styling makes the rest of the field look dated with its sharp angles and orange trellis frame and wheels. Standard ABS, Brembo-engineered brakes and a WP upside-down fork enhance the technical specifications and make the price disparity seem less of an issue.” ----- Motorcycle USA

“Based on the Duke 390, the RC390 is the new flagship of KTM’s small-displacement single-cylinder range made up of 125, 200 and 373cc models. The Duke’s proven liquid-cooled, dohc, fuel-injected counter-balanced four-stroke single serves as a stressed member of the RC’s tubular steel-trellis frame. The Duke’s 25-degree rake and 3.9-inch trail have been steepened/shortened on the RC390 to 23.5 degrees and 3.5 inches. Add in its shorter 52.8-inch wheelbase and it’s all about sharper handling response.” ----- Cycle World
