Engine & Exhaust

Based on the 1,301 cc engine of the 1290 SUPER DUKE R, aka “The Beast”, the 1290 SUPER DUKE GT is clearly the Alpha within its segment.

Engine & Exhaust

The 1290 SUPER DUKE GT packs a powerful punch for fully loaded tours, has massive torque from the bottom up and lacks the need for extensive gear shifts. It’s equally happy cruising around town as it is giving superbikes a run for their money when the chips are down. The engineers took the cylinders from the 1290 SUPER DUKE R and adapted them to a specially developed cylinder head and crankshaft to give the 1290 SUPER DUKE GT a powerplant that perfectly fits its sovereign appearance. Or would you interpret 173 hp and 144 Nm of torque, of which 114 Nm is already available at 3.250 rpm, as anything less than royal?

Cylinder head

An absolutely key element in the outstanding performance and smooth response of the 1,301 cc 75° V-twin are the unit’s cutting-edge four-valve cylinder heads. These combine twin-plug ignition, flow-optimised ports and a slick, low-friction valve train with cams from each cylinder’s twin-overhead camshafts driving DLC-coated cam followers.


The EFI mapping, in combination with the plain bearing and timing, transfer the power with low vibration and reduced engine noise. This substantially increases the smoothness of the 1290 SUPER DUKE GT power train, so you don’t have to fear for your fillings ever again.


The responsiveness and free-revving nature of the KTM 1290 SUPER DUKE GT's engine are also enhanced by the very low reciprocating weight of its crankshaft. Moreover, the flow-optimized shape of the crank webs boosts the particularly low-loss running of the crank drive.

Twin ignition

The twin-plug ignition system controls the two differently sized spark plugs in each cylinder head independently of each other in such a way that more efficient combustion and a smoother, optimally controlled combustion sequence are achieved at all times. The result: even more and even better controlled power, lower fuel consumption and lower emissions. And so the world is a better place.


Instead of the electronic injection system's throttle valves being controlled by cables, ride-by-wire processes throttle twist grip movements with the help of electronic sensors and activates the throttle valves accordingly using servo motors. However, the ride-by-wire system on the KTM 1290 SUPER DUKE GT goes the extra mile: it electronically translates the throttle commands of the rider into optimum throttle valve positions for the current riding situation. Choking, jolting and involuntary wheelies are a thing of the past. Voluntary ones, however, could easily be a thing of your future.

Slipper clutch

Not only does the slipper clutch open when the engine back-torque becomes too high, it also assists when you open up the throttle. The former prevents destabilizing rear wheel chatter when braking sharply or decelerating; the latter reduces the hand force required for changing gear, allowing the clutch to be controlled with one trigger happy finger.


The forged piston structure on the KTM 1290 SUPER DUKE GT, borrowed from Formula 1 technology, results in a high loading capacity, despite the extremely short and lightweight design. Although they have grown in diameter by three millimeters compared with those of the 1190 RC8 R, the pistons on the SUPER DUKE GT are a whole 47 grams lighter. In this way, reciprocating weight is minimized, thereby maximizing the responsiveness and frivolous nature of the engine. Furthermore, the piston skirts have a state-of-the-art, hard-anodized finish. Not only does this reduce friction, it is also particularly hard-wearing with consequently a positive impact on durability.

Service intervals

A unique mix of the highest quality components combined with a fully developed and reliable engine allows extremely long service intervals of 15,000 km. That’s a lot of adventures.



The KTM 1290 SUPER DUKE GT's exhaust system is made entirely from rustproof stainless steel and is Euro IV homologated. Hundreds of test bench runs and complex simulations ensured that the exhaust system, which is using an exhaust flap, contributes decisively to the extremely smooth torque curve and excellent emission values of the powerful twin-cylinder. And did we mention the sound? While it whispers at low revs, it will take your breath away reaching for the high notes.
