New KTM 990 Duke Bigger Is Better

Progress starts at the 947cc parallel-twin engine that KTM claims is still the most compact twin in the middleweight naked class. Little information is available beyond that, though a spec sheet comparison between the 990 Duke and earlier-generation 890 Duke R suggests that bore and stroke are both new, with the bore measuring 92.5mm (versus 90.7mm) and stroke 70.4mm (versus 68.8mm). KTM claims 123 hp at 9,500 rpm and 76 lb.-ft. of torque at 6,750 rpm. Compare that with the 121 hp and 73 lb.-ft. of torque it claimed for the 890 Duke R.
More aggressive camshaft profiles and longer valve openings are used, KTM adding that “rideability is improved due to increased rotating mass.” The stainless steel exhaust is all-new as well. Suggested fuel mileage is right around 50 mpg.
Power is managed via a very traditional suite of electronics package that includes three standard ride modes: Sport, Street, and Rain. Those modes perform as follows:
Made for spirited riding. Full power, more direct throttle control, and less traction control, allowing slight wheelspin and maximum wheelie.
The go-to mode for everyday riding. Full power, default throttle control, and traction control settings suitable for street riding. Limited wheelie allowed.
Designed for slippery road conditions. Power output is reduced to 105 hp, throttle response is smoothed dramatically, and traction control is set to maximum.
Riders are limited by how much they can adjust rider-aid settings in standard ride modes, but KTM offers a solution in the form of optional Performance and Track modes, which are available as part of a “demo program” for the first 1,500 kilometers (932 miles), but must be purchased once that number is exceeded.
Allows a certain level of customization, with a selection of traction control intervention and throttle control. Wheelie control can also be switched off and launch control can be used. Cruise control is also available.
Same level of customization as Performance but race focused, with additional lap time and bike data displayed via the dash. Cruise control is disabled.
The aforementioned dash consists of a 5-inch TFT display that includes a USB-C connection for device charging. More importantly, KTM has redesigned the menu structure for faster access to various features.
