2026 KTM 990 Duke R Review

As I chase fellow journalist Nic de Sena and KTM USA’s Chris Fillmore up the hill into Idyllwild (California), I’ve got a face-creasing grin jammed between the cheekpads of my very funky 2026 Isle of Man TT special Arai.

Watching the brake lights ahead come on, and the respective chassis dip into the corners almost in unison, is like watching a synchronized swimming contest on a motorcycle. Only this one is equipped with one of the best chassis on the market, with a soundtrack so punk it could almost come from the Vans Warped Tour.

The 2026 KTM 990 Duke R is that kind of bike. It’s a bike you ride purely because you want to get out and have a rip. It’s not a great commuter. It’s stiff and unforgiving. It’ll take you to work easily enough, but that’s not a happy place.

Where the Duke R shines is when the road makes its best cooked-spaghetti impression—switchbacks with front-tire-hammering decreasing-radius turns matched to long, fast sweepers that give the 947cc parallel-twin permission to smear its Michelin Power Cup 2 rubber into the tarmac. That’s its happy place.

The 990 Duke R is late to the sporty naked-bike party—fashionable late, some would say—but it had a good excuse. KTM famously nearly went tits up last year due to some, shall we say, reckless upper-management practices, so the fact we’re even talking about this bike is something we should be thankful for.

At $13,399, KTM’s aiming this new mini-Super Duke at the upper echelons of the sub-1000cc naked-bike class (we can’t call them middleweights anymore, right?). Think Triumph Street Triple 765 RS/RX, Yamaha MT-09 SP, Ducati Streetfighter V2/V2 S, that sort of thing.

It’s priced well, given that it’s a sharper performance steed than the base-model 990 Duke, which’ll set you back $11,999. At a quick glance, you’re getting styling and colors that take inspiration from the 2011 990 Duke R; fat 48mm fully adjustable WP Apex forks that are up 5mm over the base model, with the R model a claimed 34 percent stiffer all around; a linkage system at the back of the bike to allow for greater tunability with regard to rear-suspension setup, especially at the track; 15mm more ground clearance; Brembo Stylema brake calipers and 20mm bigger (320mm) front discs; more adjustment within the electronics and that stupendous 8.8-inch dash from the RC R Supersport bike that we’ll get to in a tick; and a claimed seven horsepower increase with power now quoted at 129 horsepower, because more power is always a good thing.

I was lucky enough to get two days on board the ’26 990 Duke R, the first in its natural habitat on the street, and the second while chasing tenths of seconds around Chuckwalla. And I can tell you straight away, it excelled in both domains, with a few caveats.

With a claimed 129 horsepower, engine performance on the street is never in question. The Duke R runs different mapping than the RC R Supersport bike, with the Duke’s torquier bottom-end punch immediately recognizable compared to the RC R’s penchant for higher revs. The 947cc twin with its specific mapping allows the Duke R to rip from corner to corner on twisty backroads, and when paired with the sharp, direct quickshifter that comes as part of the Tech Pack, life is indeed rather enjoyable on the Duke R.

You’ve got more than enough torque for 90 percent of riding situations on the Duke R, and despite the urgency in its personality, you can be lazy (if you want) by sticking it in fourth gear and lugging it from turn to turn, giving the engine internals an easier time of it. Do this, and it’s remarkable how smooth the ride is with very few vibrations coming through to the handlebars.

Engine performance is down to what mode you’re in. This being the special one, the Duke R gets Rain, Street and Sport modes, each with differing levels of throttle response, and should you pick up the Tech Pack (and you really should), you’ll get the Track mode and three custom modes that allow you to dial in damn near every performance aspect you can think of.

KTM has been a huge proponent of electronic aftermarket add-ons for years now, much to the chagrin of many customers, and the Duke R is no different.

Basically, you can buy the cruise control, Motor Slip Regulation (MSR) and quickshifter all separately, or you can buy the Track Pack, which gives you the Track and extra Custom ride modes, five-stage anti-wheelie, launch control, nine-stage plus off MTC slip adjust, lap timer, and the telemetry screen for $499.99.

Or, you can chuck an extra $400 in and spend $899.99 to get the full-house Tech Pack, which gives you everything in the Track Pack plus cruise control, MSR, and the quickshifter, so just go with that.

It is a bit of a kick in the gut to have to pay an extra $900 to get all this stuff on the premium bike in the 990 Duke range, especially when you can buy a Yamaha MT-09 SP for $12,699 and get every possible electronic add-on the company makes. However, once you get the Tech Pack, it’s all done, and you have either a near-perfect street bike, a hardcore track bike, or both.

Everything is adjusted by that fantastic 8.8-inch TFT display, now my favorite on any production motorcycle. It’s a touchscreen, so intuitive to use, and you even get little pictures, so if you’re a complete dumbass like me, you still know what you’re adjusting.

KTM is running its own map software, so you don’t even need to pair your phone to the bike to get turn-by-turn navigation, which is a serious win in my book. There’s so much adjustability in there it’d take me a week to get through it all, but at a glance, KTM’s solved a problem most haven’t—make the dash easy to use. That’s it. It’s amazing how convoluted some people make their dashes.

With a claimed wet weight (that’s including a full 3.9-gallon tank of gas) of 394.6 pounds, the Duke R’s ability to navigate twisty switchbacks is unquestioned. Compared to the Heavyweight 1390 Super Duke R, the 990 is at best a Super Middleweight, light on its feet but efficient in its power and speed, zipping you from corner to corner but having the chassis to back it up.

Much of this character trait is down to the Michelin Power Cup 2 rubber, which provides excellent edge grip, braking stability, and more than holds its own when you open the throttle. You really have to try hard to get the Michelin to step out, certainly harder than I would be comfortable with on the street, although I can’t yet comment on wet-weather performance.

Transfer the 990 Duke R to the track, and things get a little spicier. Slap on some hard-compound R7 front and R8 rear Dunlops, and things get spicier still. Funnily enough, the Duke R’s corner-slicing performance on the street didn’t directly translate to the track, instead requiring a fair bit of suspension fiddling to get it to handle as I’d hoped. I never did get there, but I got close.

The Duke R runs a 0.75 rear spring, which is way too light for me at 210 pounds. Back when I was racing Supersport at Chuckwalla every other week, the minimum I ran was a 0.95 spring, but I can’t remember how many turns of preload I ran.

If you’re under 170 pounds in full leathers, you’ll probably be okay, but anyone above that will want to increase the rear spring rate to help achieve some decent lap times.

Over the day, I gave the Duke R’s shock five turns of rear preload, and it still wasn’t enough to stop it from sinking in the back-end and running wide when the throttle was first applied, but once I knew that was as good as I’d get it without pulling the shock out, I backed the pace off a touch and just enjoyed the ride.

What stood out on the track is how well the Duke R braked and how the electronics worked seamlessly in the background. It was a case of wheelie control off, traction control on level two, and leave the rest to the computer.

The engine was a known quantity, and even though we didn’t stretch it out on the road, its on-track performance wasn’t all that surprising. It’s when you get off the gas that the Duke R really shines. Braking performance from the Stylemas is exceptional (remember when Stylemas were the absolute be-all and end-all of Brembo braking power?), and you’ve got a quality Brembo MCS master cylinder and cornering ABS to provide the electronic safety net. The chassis is ultra-stable under brakes, allowing it to make upright-to-on-its-side direction changes without getting all nervy at the front.

With a bit of setup time and a new heavier spring, I’ve no doubt you could start setting some seriously quick lap times on the Duke R. The best thing is how the chassis talks to you—yes, it wasn’t perfect in its setup, but it never once felt like it was going to throw me down the road regardless of how hard I pushed it.

That characteristic shines through in most situations you find yourself in on the Duke R. It fulfills the hooligan brief better than any midsize Duke that came before it, even going so far as to encroach on the big daddy 1390 for sheer laughs and face-hurting smiles. There’s almost never been a better bike for the “you don’t need a 1000cc-plus bike” argument than the 990 Duke R. It looks nasty with its orange subframe and funny Predator-looking face, has a superlatively bratty engine, and will ace your local backroad as good as bikes three times its price.

I really enjoyed the 990 Duke, but in the 990 Duke R, I may have just found a new favorite, now that it’s finally here. It is, indeed, about bloody time! CN
