KTM 990 Duke (MY2025) vs 990 Duke R (MY2025)
KTM 990 Duke MY2025 vs 990 Duke R: no fairing, no excuses. Here's how to pick.
Pitch the KTM 990 Duke MY2025 into a corner and it drops in light, with its bars reporting what the front tire's doing. The KTM 990 Duke R stays planted and doesn't squirm.
So which one do you buy?
The 990 Duke R has the edge if…
Sporty riding on twisty roads
By a nose: 990 Duke R
On a winding road, the 990 Duke R comes out a touch ahead. Put it down to stronger brakes and better suspension. You wouldn't bet much on a gap like that.
Daily commuting & city riding
Nose ahead: 990 Duke R
The 990 Duke R makes slightly more sense as a commuter. Don't read much into a gap this small.
What makes each one tick
990 Duke MY2025
The 990 Duke's short first gear runs out early to pack the twin's low-end shove into a city block or a canyon entry. The engine doesn't wait. A crack of the throttle brings hard pull off the bottom, and there's no flat spot on the way to the limiter. The tank swells toward the seat and draws you in.
Nils rode the 990 Duke MY2025 in Austria in 2025 (NastyNils Testride).
990 Duke R
The Duke R's stiffened trellis frame gives the chassis a hard supermoto edge. Brembo Stylema calipers haul it down hard, and the lever's feel doesn't fade. The twin hits hardest up top.

Which one for the way you ride
A confidence-building first motorcycle
Neither one fits
Both of these ask too much of a rookie. Spend your first year on something lighter.
Traveling with luggage
Both miss here
Both of these make awkward travel bikes. Pack light and keep the trips short.
They come out level on running costs. The better-kept used example is the smarter money.
