KTM 990 Duke vs 990 RC R: where they split, and which one to buy.
Into a corner, the KTM 990 Duke's chassis settles onto the line you've picked and it stays planted there. The KTM 990 RC R's front tire keeps you posted on grip right up to the edge. The bike doesn't shuffle as the bars go over.
So which one do you buy?

Daily commuting & city riding
Hands down: 990 Duke
The 990 Duke earns its keep in weekday traffic better than the other one. For a daily commuter, it's the clear choice.
What makes each one tick
990 Duke
From a weekday commute to a hard weekend session, the 990 Duke's seat and suspension hold the same manners, and the damping stays soft enough that daily miles don't wear on you. Stopping power at the brake lever trails the rest of the bike. Lever bite can vary between bikes. The fork's still talking as you trail-brake in.
Nils rode the 990 Duke in Austria in 2024 (NastyNils Testride).
990 RC R
The narrow twin keeps the 990 RC R slim enough that it steers into a bend at a nudge. With rear ABS switched off, you can break the rear loose on the way into a corner, or just before it. Braking deep into a corner with the bike still leaned over is easy to control, and the Supermoto ABS mode works very well on corner entry. A bump barely stirs the frame, since the stock fork and shock already sit on the sporty side. There's real pull from low revs, and it doesn't fade through second gear. Third gear keeps right on shoving.

Which one for the way you ride
Comfortable long-distance riding
Both miss here
Neither one is built for long-haul comfort. For big miles, look at a proper tourer or sport tourer.
A confidence-building first motorcycle
Neither one fits
Neither one is where you should learn. Get a season on something gentler first.
Don't look for a gap on twisty roads and running costs: there isn't one. Go by how each one fits you.
