2024 KTM 1390 Super Duke R Evo

There is no question that the Super Duke is KTM’s flagship sportbike, and it just so happens to be a naked. For years, the 1290 Super Duke has been an overachiever. And while no one ever accused the bike of being soft, for 2024, KTM decided to put more chips into the pile, or in this case more cc’s of displacement, more power and more of what has made this bike so potent. Meet the 1390 Super Duke R Evo.

The Super Duke has always been a purpose-built hooligan machine, and instead of being based on a sportbike that’s been stripped down, it is the bike that other models in KTM’s lineup use as a platform. That’s because this beast has so much raw energy.

Despite the naming protocol, the 1390 actually has a new 1,350cc version of the LC8 V-twin, which is 49cc larger than the 1,301cc “1290″ it replaces. Bore has been increased by 2mm from 108 to 110mm, while utilizing the same 71mm stroke. Claimed power is 190 hp at 10,000 rpm and 107 lb.-ft. of peak torque at 8,000 rpm. The previous 1290 made a claimed 177 hp and 103 lb.-ft. of torque.

In order to increase power and still maintain emissions compliance, KTM has added variable valve timing to help achieve strong low-rpm torque, while not sacrificing top-end performance. A new airbox with more volume, a new ram-air system, and larger 60mm throttle bodies feed the engine mixture.

The chassis features a frame that is very similar to the previous generation’s. But the suspension is KTM’s latest gen-three version of WP’s Semi-Active Technology (SAT). Riders can choose between five suspension damping modes including: Auto, Comfort, Rain, Street, and Sport. Opting for the Suspension Pro package adds Track and Pro modes. Braking is handled by top-of-the-line Brembo Stylema Monoblock radial-mount four-piston calipers with 320mm discs up front, and a twin-piston caliper and 240mm disc at the rear.

With a bike this gnarly, electronic rider aids are a must. Standard nonadjustable modes include Rain, Street, and Sport. Once again, opting for an optional package adds additional modes including Performance and Track modes, which allow customization of areas like traction control, wheelie control, engine-braking, and so on.

All-new bodywork, styling, and lighting complete the big changes for 2024.

The 2024 KTM 1390 Super Duke R Evo is available in orange or black starting at $21,499.
