The 2024 generation 390 Duke is 90% new and it shows. The engine grew to 399cc and now produces 44bhp with noticeably more midrange than the old 373cc motor, while still sitting inside the A2 licence limit. It revs hard, pulls cleanly from low down and has the aggression KTM have always built into these, which is why the Duke has dominated this class for over a decade.
The chassis is all new too. A new frame with the subframe integrated as a load-bearing part, open-cartridge WP APEX forks with five-step compression and rebound adjustment and a WP APEX rear shock, also adjustable. At 165kg it is light, flickable and genuinely quick on a back road, with a four-piston radial caliper on a 320mm front disc giving far more braking power than a bike of this size needs.
Equipment is way ahead of the class. A five inch colour TFT dash with Bluetooth connectivity and turn-by-turn navigation, ride-by-wire with two riding modes, cornering ABS with a Supermoto setting that lets you lock the rear, traction control, launch control on later versions, and a bi-directional quickshifter available as an option. Full LED lighting throughout.
This one is a 2025 model, effectively a brand new bike. This duke feautres two keys and is yet to have its first service.
