Just when enthusiasts believed the pinnacle Super Duke had reached its zenith in terms of power, speed, and technology, KTM unveils the 2024 1390 Super Duke as the successor to the 1290 Super Duke. Dominating the naked sports bike class since 2005, the Super Duke family has consistently set the bar high, and KTM’s engagement in MotoGP since 2017 has facilitated advancements in chassis, engine, and electronic technology, all of which have seamlessly translated to their road bikes.

The 1390 Super Duke introduces a host of upgrades, including entirely new bodywork, a sleeker profile, more compact packaging, aerodynamically optimized winglets for enhanced downforce, the latest WP semi-active suspension, and an additional infusion of raw power. It represents an evolutionary step forward for the model, showcasing KTM’s commitment to continuous improvement rather than a revolutionary departure from its successful lineage.
Brief History of KTM Super Duke
The Super Duke narrative commenced in 2005 with the introduction of the 990 Super Duke by KTM. Propelled by a 75°, 999cc V-Twin engine, the initial model boasted 120 horsepower and 73 pounds-feet of torque. Over the subsequent eight years, KTM consistently refined and enhanced this powerhouse. In 2013, the 990 Super Duke was succeeded by the 1290 Super Duke, distinguishing itself as part of the Super Duke lineage, exclusively reserved for V-Twin engines, while single-cylinder and parallel twin models retained the Duke nomenclature.
Over a decade of meticulous development transformed the 1290 Super Duke into a formidable contender among naked sports bikes. With escalating power, refined electronics, and a reputation for its uncompromising nature, the 1290 Super Duke left an indelible mark. Fast forward to 2024, and KTM has announced the arrival of the 1390 Super Duke, signaling the retirement of the 1290 model. The 1390 Super Duke R Evo now claims the zenith in KTM’s lineup. Interestingly, the Duke 990 is poised for a comeback, adding a nostalgic touch to KTM’s impressive portfolio.
The 2024 iteration of the KTM 1390 Super Duke R Evo boasts an upgraded and larger engine
Similar to how the 1290 Super Duke’s engine actually measured 1,301cc, the 2024 1390 Super Duke R Evo doesn’t have a 1,390cc displacement but rather boasts an actual capacity of 1,350 cc. While it’s just a modest increase of 49 cc compared to the 1290 Super Duke R Evo, this adjustment results in higher power and torque figures: 187.7 horsepower (an increase of 7.7 horsepower from the 1290 Super Duke R Evo) and 106.9 pounds-feet of torque (a boost of 3.9 pounds-feet).
The enlargement of the engine’s displacement is attributed to a new bore size, growing from 108mm to 110mm. Additionally, the enhanced engine now features variable valve timing, incorporating a cam shift system reminiscent of the BMW Shiftcam system. This innovation contributes to a more extensive spread of power and torque across the entire rev range.
The 2024 iteration of the KTM 1390 Super Duke R Evo receives an infusion of additional technological features
Aligning with the current trend in the motorcycling realm, the ABS and traction control systems on the 2024 KTM 1390 Super Duke R Evo are now responsive to lean angles. Standard configurations include three riding/power modes: Rain, Street, and Sport, with the option to access Performance and Track modes as additional and discretionary features.
For enthusiasts inclined towards wheelies, the 2024 KTM 1390 Super Duke R Evo offers a system that accommodates five distinct angles of front wheel lift, ranging from a subtle 0.36° to an attention-grabbing 22.25°. For those feeling exceptionally audacious (or perhaps a bit reckless), this system can be deactivated entirely. Other notable features include tire-pressure monitoring and engine brake control, providing users with five levels of adjustment for a customized riding experience.
The 2024 iteration of the KTM 1390 Super Duke R Evo is equipped with semi-active suspension technology
One notable distinction between the ‘base’ 1390 Super Duke and the ‘Evo’ model lies in the adoption of WP semi-active suspension on the latter. Initially introduced in the 1290 version in 2022, this concept has undergone further refinement for the 2024 model, now featuring WP’s third generation of electronic suspension technology. This advanced system is designed to cater to a spectrum of riding experiences, ranging from everyday comfort to focused track day maneuvers.
Eliminating the need for manual adjustments, the motorcycle’s onboard Suspension Control Unit (SCU) utilizes magnetic valves to dynamically adjust damping rates during the ride. This adjustment is informed by data from stroke sensors and the Inertial Measurement Unit (IMU). Users can conveniently choose settings through the TFT dash, with the bike offering five damping modes as standard. Opting for the Suspension Pro pack introduces ‘Track’ and ‘Pro’ options, unlocking three auto-leveling settings. These settings automatically adjust preload based on the rider’s weight, creating three preset geometries. Additionally, the front forks feature an anti-dive setting, ensuring stability under intense braking conditions.
The 2024 KTM 1390 Super Duke R Evo is well-suited for riders of shorter stature as well
When Harley-Davidson introduced the Pan America adventure bike, a standout feature was the self-lowering rear suspension, addressing a significant challenge for shorter riders. While it was expected that competitors would develop similar systems, the application of such a feature on a naked sports bike wasn’t anticipated.
The 2024 KTM 1390 Super Duke R Evo, however, has embraced this innovation. Informed by MotoGP technology, it incorporates a ride-height system at the rear that lowers the bike when exiting corners, enhancing acceleration. The redistribution of weight towards the rear is believed to contribute to improved off-the-line acceleration. This not only enhances the already formidable performance of the 2024 KTM 1390 Super Duke R Evo but also ensures that shorter riders are not deterred by the challenge of reaching the ground when the bike is stationary.
The Factory Start System of the 2024 KTM 1390 Super Duke R Evo
Known as the Factory Start system, this suspension-lowering mechanism operates independently of Launch Control. Factory Start becomes inactive and restores the rear shock preload to its normal setting under several conditions. These include when the motorcycle achieves a speed of 18 MPH and is in 4th gear or higher, when the speed hits 18 MPH and the throttle is closed, when the bike reaches 18 MPH with a lean angle greater than 30°, or when the Rider switches ride mode.
Upon deactivation, the preload reverts to the previously selected Preload Adjuster mode on the dashboard. Despite the intricate conditions, the automatic activation and deactivation by the bike itself allow the rider to largely disregard the system and focus on navigating the upcoming corners. The added reassurance comes from the presence of lean-sensitive ABS, ready to assist should the rider need to adjust speed mid-corner.
Summary
KTM has disclosed pricing of $21,499 for the 2024 KTM 1390 Super Duke R Evo, positioning it in direct competition with notable counterparts such as the BMW S1000RR (205 horsepower), Ducati V4 Streetfighter (208 – 231 horsepower), MV Agusta Brutale 1000 Serie Oro (212 horsepower, priced at $45,998), Triumph Speed Triple 1200 RS (180 horsepower), and Aprilia Tuono V4 (175 horsepower, priced at $16,199).
