Just so we’re clear: While it is technically correct to say this new street-legal KTM 990 Duke R is the leveled-up version of the standard 990 Duke, it is more accurate to say it was created to live happily ever after on the racetrack, aggressively chopping wood lap after glorious lap along the way.


The 990 Duke R works great on the street but absolutely loves the track.

In fact, the prototype of this R model was shaken out at Mid-Ohio in the Super Hooligan class and performed exceedingly well in the hands of KTM’s Media Relations Manager Chris Fillmore, a former professional racer. As a result, the 2026 990 Duke R represents a multiyear effort to build a true-to-form, track-capable weapon that remains street-legal.


Light and compact, the 126 ponies in the 990 R pack a punch everywhere in the rev range.

My journey kicked off in Palm Springs, California, where KTM provided a technical briefing on the 990 Duke R and clarified that it is manufactured in Austria (even though KTM is part of Bajaj Mobility, the 990s are not built in India like its 390 models).

KTM covered the route plan and other housekeeping details, but by then my brain was preoccupied by how racy the bike looked resting on the track stand, with that big fat “R” on the tank. It looked alive, like it had Red Bull flowing through its orange tubular-steel frame and had somewhere very important to get to. It seemed to get angrier the longer it sat there.


Up-spec suspension and brakes are just some of the party starters that make the R special.

But I needed to acclimate to the little details first, like the vibrant new 8.8-inch TFT display, which is navigable via touchscreen or buttons on the left bar cluster. It also contained a split-screen function that allowed me to click and drag the widgets to whatever proportions I desired. I clicked and dragged my map to one half of the screen and left the rest of the screen to toggle through other details like ride mode, speed, gear indicator, etc.

Like other modern KTM’s I’ve tested, this new 990 Duke R has a wide range of adjustability available via menus on the TFT display, such as standard ride modes (Sport, Street, Rain, and Custom) and optional ride modes (Track and two more Custom modes) available as part of the Tech Pack. But the real showstopper here is that you can drill down into each ride mode and fine tune settings for throttle response, launch control, ABS, traction control, anti-wheelie mode, quickshifter, and more.


Fully adjustable WP Apex suspension is combat-ready. Are you?

Once I mounted up and the music started, I immediately noticed the short, stout posture of this naked platform and the low, flat, high-leverage handlebar. It felt sharp under me. When I toggled the Start button, the compact LC8c parallel-Twin had a pronounced growl that alluded to its 126 hp with 10,500-rpm rev limit. Response was exceedingly smooth. No snatchy throttle, no flame out off-idle, just calm forward movement.

But right about here is where I had a miscue, accidentally toggling into Rain mode, which immediately muted the power and set the anti-wheelie and other safety settings into overdrive. Quick snaps of the throttle felt more like gentle supportive taps. To remedy this, I rashly overcompensated and selected Track mode at the next traffic light, unleashing all kinds of high-performance parameters and unlocking launch control.


The 8.8-inch TFT display with split screen shows you everything you need to know.

I know what you’re thinking. But no, I did not use launch control on the street. Did it occur to me? Of course it did.

Heading out of town, we jumped on the freeway, which, as you already know by looking at this motorcycle, is where it shined like a diamond. If you are familiar with the base 990 Duke, the pegs on the “R” model sit 1.3 inches farther back and 0.5 inch higher, with the handlebar sitting 0.4 inch lower and 0.9 inch forward. Still, my well-worn 6-foot-2-inch frame managed the wind buffeting for the 20 minutes we engaged KTM’s rarely accessed “morning commuter” mode. Much farther might have been uncomfortable.


You want ride modes? The 990 Duke R has plenty. And then some.

Once we jumped into the twisties, I began learning what that “R” designation really means. First off, the 990 Duke R is equipped with fully adjustable WP Apex suspension, with a beefier 48mm fork than the 43mm one on the base model. The rear shock is adjustable for both high- and low-speed compression in addition to preload and rebound, and it’s mated to a new linkage-suspension designed to deliver small bump compliance while maintaining the composure necessary for track duties.

From my seat-of-the-pants perspective, the higher-spec suspension contributed to a firm and exceedingly stable platform when I dropped the bike into turns. I remember thinking that it felt as if there were two of me going around the corner: one sitting over the front tire and the other over the rear. It was wonderful but weird, because in my experience firm suspension tends to mean firm everywhere, so I expected the fork to be harsh when I loaded it under braking. However, when it was time to pick myself up out of the corner and trail the brakes into the next one, I found the fork to be smooth and compliant, moving through the stroke just enough to plant the front end while preparing me for yet another happy drop.


Mid-corner lock down: A Sherman tank couldn’t knock the 990 Duke R off its line.

It was right around this point in the ride where I donned my scientist cap to see exactly how planted and stable the 990 Duke R really was in the turns. As you probably know, being mid-corner with decent lean angle is not the best time to start jacking around with shifting and throttle inputs. On the contrary, we want to keep the chassis as stable as possible to maximize our available traction. My test bike was equipped with Quickshifter+, which generated seamless rapid upshifts and rev-matched downshifts. I started fiddling with it to see if it would unsettle the chassis in the corners. But nothing happened. Sure, I could hear the revs change, but the shifts were so clean and smooth I couldn’t feel them from the seat of the pants. The damn bike didn’t budge; it just held its line and remained glued to the ground. In response, I bumped my experiment to Defcon 1 and started playing with the throttle, requesting ham-fisted power pulses to be sent to the 180/55 Michelin Power Cup 2 tire, but still the bike remained locked down and composed, maintaining a clean line all the way through the corners.

The rest of the day was mostly canyons, so I had plenty of time to give the throttle a workout. Interestingly, the 126 horses generated by the 990 Duke R were exciting and fun but never intimidating, no matter the situation I was in. I never felt that the motorcycle was going to react in a strange or unpredictable way when I twisted the throttle. On the contrary, it exhibited a nice balance of raw torquey power and high rpm pull without punishing me for mistimed inputs.


The 990 Duke R has loads of ground clearance without compromising rider comfort.

The next morning, we packed up and headed to Chuckwalla Raceway, which sits in the middle of the desert an hour east of Palm Springs. To be perfectly honest, I was mildly nervous about the day. Why? Well, for starters, I’d never spun any laps at Chuckwalla and I was going to be on track with national pro-level journalists and staff, with all the bikes getting race slicks and tire warmers for added intensity. But maybe the biggest cause for concern was the fact that I was only 5 weeks post-op from total knee replacement surgery. Yes, my doctor eventually signed me off after I promised to leave his office, and I did have a bit of seat time on my BMW R 1300 RT-P a few days prior to this launch, but riding a new motorcycle with legitimate racers on an unfamiliar racetrack is a whole different level of stress.

Luckily, a few minutes before I pulled into Chuckwalla, I remembered my tried-and-true police motor competition routine to help calm my nerves: a Starbucks iced latte and a chocolate croissant. Caffeinated and carbo-loaded, I was ready.


With ample leverage in the bars, the 990 Duke R is razor-sharp when it’s time to guide it into the turn.

After I got suited up, I headed over to the riders meeting, where KTM’s tech staff said they bumped up our suspension base settings from Street to Sport. In doing this, it reconfigured all aspects of the various clicker adjustments that impact damping, essentially stiffening things up for the additional forces the track (and slicks) were going to dish out. Staffers also brought to our attention that the taillights and mirrors were removed, a quick two-minute process to get the bikes ready for the track.

I discovered another cool track-related part on the 990 Duke: a Brembo MCS radial master cylinder. This “Multiple Click System” enables the rider to adjust the mechanical ratio of the lever by changing the lever pivot distance. I set it at the mid-level (20mm) mark and noticed right away it generated a somewhat quicker and shorter response when I pulled the lever.


Initiate the drop: The 990 Duke R falls into turns almost as soon as you think it. Sublime.

GEAR UP: TRACK​

• Helmet: Schuberth S3
• Suit: Mithos Custom Kangaroo
• Airbag Vest: Alpinestars Tech-Air 7x
• Gloves: Lee Parks Design Sumo R
• Baselayer: VNM Activcool-GP Compression Pant
• Shorts: Bohn Adventure All Season Armored
• Boots: Richa Speedmaster
• Glasses: Flying Eyes Cooper Aviator Narrow

With the green flag flying, I headed out to acclimate to the track. Lucky for me the group of seasoned journos was generous enough to ease the pace and “tow” me around the track, showing me the correct lines along the way. Still, we carried enough speed in the first session to feel the knee puck test the power ceiling of the ibuprofen as it roared through the bones and muscles attached to my new titanium joint.

By the second session, the KTM 990 Duke R began to express itself, because at that point I knew the track, wasn’t concerned about my new knee, and trusted the tires completely. The first thing that stuck out was that damn motor. Chuckwalla has two straight sections, but most areas are double-apex turns and short blasts between corners. And with this 990 Duke R, I was able to hold gears out of a corner and let the motor scream from the rooftops all the way to the next one, without the motor falling on its face. Insanely fun.


The complete package: The 990 Duke R was purpose-built for performance and only gets better with time.

And do you remember how I raved about the chassis composure when cranked over mid-turn during my street ride? Nothing changed on track, even though the speeds and forces were much higher. The 990 Duke R was planted and held its line beautifully. Did the Sport settings feel firmer than the Street settings? Absolutely. But still so composed that it compelled me to start rolling on throttle earlier and harder during corner exits. And the brakes? This new R is equipped with radially mounted, 4-piston Brembo Stylema monoblock front calipers that offered one-finger-stoppie levels of power lap after lap, with no fade or change in lever travel. Much like I’d been discovering about other components of the R, the brakes were assertive but not overly aggressive, so I never worried about grabbing a poorly measured handful. Even when I overcooked a few turns because I forgot I wasn’t a national pro.

Did I have any complaints or concerns while I ingested more orange Kool-Aid as the day went on? Well, I did inquire about some false neutrals during a chicane-elevation-change section, explaining that a few times while leaning into a right-hander, the bike would lose power and free rev. It turned out that the Quickshifter+ can be gently “bumped” in-between gears if your boot placement is a bit off, which it was at times due to my squirming around to get my knee comfortable. They offered to make an adjustment to the shift lever for me, but I declined, deciding instead to pay closer attention to my foot. I never had the issue again.


No matter how hard you push it, the 990 Duke R just laughs and keeps pushing.

I’ll close with this suggestion: Buy a 2026 KTM 990 Duke R, take it to a local track day as much as you want, hit the rev limiter, engage the launch control, and scream your head off. You won’t have more fun than this. And sure, if you want to cruise around on the street, commute on it, and hit some backroads, absolutely go for it. But don’t say I didn’t warn you when this thing starts getting angry because you let it sit for too long.


The 990 Duke R doesn’t like sitting still.
