The new KTM 790 Duke, Nicknamed “The Scalpel”, is a smaller, more nimble sibling to “The Beast”, aka the KTM 1290 Super Duke R.

The ‘LC8c’ as it’s known produces 102bhp @ 9,000rpm which is a significant boost over the 73bhp from the single-cylinder belonging to the 690 Duke and the new machine is expected to be far sportier with extreme lean angles on offer.

Familiar WP suspension comes in the shape of 43mm USD forks, a steering damper and an adjustable shock while the cornering ABS with ‘Supermoto’ mode is one we’re looking forward to trying. Four configurable riding modes, launch control plus quickshifter+ for up and down shifts.

An A2 licence option will also be available and the 790 Duke is offered in two colours (black or traditional orange) while 30 accessory parts allow for customisation. Two pre-defined set-ups are on offer, named RACE and STYLE.

Engine & Exhaust

Meet KTM’s first inline twin: the LC8c. That ‘c’ stands for compact, ‘LC8’ for good times ahead.

Chassis

Purity is the focus here. All components have been reduced to the bare essentials. There are no unnecessary parts or covers. The engine, for example, doubles as a load bearing element, the frame is made of extra strong CroMo steel so less material is needed, and components were developed to combine functions wherever possible.

Ergonomics & Comfort

The bike has been made to feel as compact as possible while accommodating a wide range of riders. The goal? Confidence.

Bodywork & Graphics

Purity is one of KTM’s brand values, and in a design context it means not using unnecessary design elements when a simpler option is possible. Or when you can combine multiple functions in one part. Take the tank spoiler, which combines the functions of spoiler and ergonomic surface, for example. Or the taillight that’s been mounted on the license plate holder, so it can be easily removed for a day at the track. This is a bike that looks and feels as compact as possible. You’ll find no round shapes, but straight lines, clarity and the promise of a radically thrilling ride.

Software & Electronics

The KTM 790 DUKE comes with some serious brainpower as standard. Even when you’re flirting with the limit, KTM’s combination of the most advanced software and electronics in the world of motorcycling will have your back. All you have to do is focus on the road ahead – and hold on tight.

Accessories & Luggage

KTM know its customers like to modify and to travel, which is why the PowerParts range boasts a huge variety of accessories and luggage options across its Street range of sportmotorcycles – past and present. All PowerParts are developed alongside their chosen machine, meaning that KTM riders only get parts that perfectly complement their ride and provide that important ‘factory fit’ straight from the dealer.
