2024 Ktm 990 Duke Reviews. Ktm made a big leap forward with the 2024 990 duke. A big upgrade over the 790 and 890 it is, but it invites a few more questions from a 790 duke owner’s perspective.

The ktm 990 duke is 96% a new. A new 1.5 kg lighter swingarm has actually had its stiffness reduced in a bid to give a little more flex for bump absorption and stability on the rear.
