New 1390 has more power and tech than its 1290 predecessor
KTM HAS LAUNCHED a 187bhp 1390 Super Duke R range for 2024 – powered by a monstrous 1350cc motor.
Available in a standard and Evo guise, the duo will take over from the 1301cc 1290 Super Duke selection that first shook up the supernaked scene 11 years ago.
The new bikes get a revised LED headlight design similar to the recently-revealed 990 Duke and they’ve grown a set of subtle winglets that droop below the shoulders of the larger 17.5-litre fuel tank. Lowering unsprung mass is a set of Michelin Power GP-shod 17in rims weighing 1.2kg less than before.
Based on the existing V-twin found in the outgoing 1290, the higher capacity has been achieved thanks to an increased bore of 110mm, up from 108mm. You’ll also find a new ‘cam shift’ system – otherwise known as variable valve timing – that allows for a claimed broader spread of power and torque across the rev range.
KTM says that alongside more performance, both durability and serviceability were also considered – meaning valve clearance checks are now only needed after 60,000km (37,282 miles).
There’s also a redesigned airbox, shorter throttle bodies and a revised ram air system for more direct airflow into the engine.
Furthermore, both fifth and sixth gears’ ratios have been revised to allow for use over a wider speed range.
Elsewhere, the standard R gets a set of fully-adjustable
48mm WP Apex forks as well a
