2026 KTM 990 Duke R vs KTM 990 RCR Review | Road and Track Test

I was so impressed after riding the last Duke 990 at the 30 years of Duke festival in Spain that I ended up buying one. They’re seriously good on the road: great handling, amazing front end, super accessible performance and just bags and bags of fun. So when the invite landed in my inbox to test KTM’s latest 990 cc road siblings at Sydney Motorsport Park, you can imagine that my reply was swift and emphatic. With the Duke priced from $23,990, the RCR another $1000 on top, both bring strong road and track credentials but target different riders.

A day riding these beasts around Sydney Motorsport Park? Oh, alright then…

I got to ride both the 990 Duke R and 990 RC R back to back on a track that I’d not previously had the pleasure of ticking off my list. Bring it. To quote Team Orange’s marketing for the launch: #neverstop twisting the throttle.

I was already relatively familiar with the Duke R given that I own a Duke 990, but the RC R was a new experience

Road-going KTM RCs have an interesting backstory. The RC8 was introduced in 2008. All angular lines and futuristic looking, it was a polarising design that took a little time to land for some, but has aged quite well. KTM supported the RC8 and its successors, the RC8R and RC R Track, in a number of racing series, including Australia, until they backed away from building road-going RC bikes, citing rider safety concerns at the time.

Jeremy McWilliams helped develop the original KTM RC8R and was also involved with the latest Duke and RC R development

The first signal that they’d changed their minds on that front was the RC8C of 2022. With a limited run of only 100, these were track-only pieces of exotica. They used the same base LC8c parallel engine found in the two 990s on test here, but it was wrapped in a very trick, lightweight chassis and tipped the scales at 142 kg dry. Costing roughly 60 big ones to you and me. If only. And in the metal, they look even better than pics do justice.

The RC8C in the lineup at SMSP was sadly ‘display only’. What a lovely thing…

And then, of course, the well-publicised financial shenanigans happened, which put a pause on getting the full production, road-going version of that bike to the masses. Well, my friends, wait no more. It’s here. I’ve ridden it – and I can tell you it’s every bit as good as the Duke R is, which is probably no surprise.

The similarities between the RC8C and the RC R are certainly there to see

Which 990 Suits You Best?

What was a surprise, though, was just how different the two bikes feel when you ride them back to back. And to answer what will be most people’s first question – no, the RC R is most definitely not just a Duke R with a fairing.  Tested back-to-back at Sydney Motorsport Park, KTM’s 2026 990 Duke R and 990 RC R share the same LC8c twin but deliver very different road and track experiences.

A shared heart

Let’s start with the similarities first. Both bikes utilise the same LC8c 947 cc twin cylinder that now punches out just on 128 hp. Up around 7 on the previous generation. It’s a cracking little engine. Physically, it’s quite small and lightweight, enabling excellent packaging and positioning within the frame for optimal handling. But the positives don’t end there. It has tremendous character, with a wonderfully eager bottom end and a midrange that keeps giving as the revs build into a proper top end.

That cracking LC8c engine is shared between both bikes, with slightly different tunes

Fuelling is excellent, and despite being now Euro 5+ compliant, there are no apparent dead or flat spots anywhere across the rev range. Gone are the days of old when 1,000 cc twins were grumpy sons-o-bitches that needed nursing from idle through to around 3000 rpm before they started working. The LC8c will pull from pretty much idle. Smooth, fuss-free grunt.

990 Duke R vs 990 RC R: What changes?

There are some differences in tune between the two. The Duke has a slightly punchier map in the low to mid range, and the RC R is ever so slightly softer down low, but with a slightly stronger top end – in line with its more focussed ambitions. I think they’re both pretty spot on in their respective roles.

Slightly punchier down low in the Duke R tune and with an ever so slightly stronger top end in the RC R

The bikes also share the main chassis that wraps around the engine, and a whole host of electronics improvements over the previous generation. They’ve made some big steps forward here, actually, so let’s focus on that for a bit.

Seriously good tech

The new landscape dash is the obvious one. And it’s super nice. Kudos to the team at Kiska for smashing it out of the park design-wise. Big, bold display is as easy to use and read as it is attractive. While I’ve never been a fan of duplicated tachos (and was super critical of it on some Triumph dash designs where it was overly fussy) – I’ll accept it here in its relative simplicity.

New letterbox shape dash is touch screen and works brilliantly

The physical screens themselves are also touchscreen. And while that might sound like a bit of a gimmick at first, when you’re trying to connect your phone to the bike and can use the touchscreen to put in a pairing password quickly… or tap in an address for the gloriously sized mapping and turn-by-turn nav… you’ll soon appreciate just how useful it is.

Out on the road later in the day, the touch-screen turn-by-turn navigation proved to be excellent

Plenty of the riding modes as expected (Rain, Street, Sport and Custom come standard), so I won’t dwell on them too much. Although surprisingly, the electronics will allow you to use both cruise control AND turn-by-turn navigation within the track mode (available with the tech pack, which also gets you an additional Custom mode), which is excellent.

New switchgear left and right. Much improved adjustment of TC and separation from cruise control adjustment over the old model

That Track mode allows you to fine-tune TC on the go via the lower-left-hand paddle switches, and lets you adjust wheelie control from low to extra high, or even off. Which I may have had a play with on the photo shoot. Just to be thorough. For you folks. Not for my own enjoyment at all.

Can confirm that wheelie control can be turned off…

Of course, the electronics will also let you adjust the expected settings, including your throttle feel and mapping, and fine-tune your braking style with modes for street and sport, plus Supermoto + for even more shenanigans. You get one custom map as standard and a second custom map when you opt for the Tech Pack. Personally, I’d leave it in Track mode everywhere. It was just as great on the road as it was on the… well, track.

New right-hand side switchgear – super easy to use

Other noteworthy upgrades – the switchgear design has been improved and now separates cruise control operation from the ‘TC’ adjustment paddles. This is a welcome usability improvement in my book (having been a source of frustration on the previous gen).

Suspension gets an upgrade

The other big change on the Duke, shared by both bikes, is the move from a 43 mm Apex Pro fork to a 48 mm unit, along with the addition of a linkage assembly to the rear suspension. This linkage allows for a longer effective shock length even though the shock itself is now physically 10 mm shorter at 140 mm. To you and me, that means more control: specifically, better small-bump absorption at the top of the stroke without compromising performance under heavy load near the bottom of the stroke.

Updated WP Apex Pro now moves to 48 mm. The RC R shown here has slightly less travel than the Duke R

The seat height on the Duke R has also been upped by 15 mm, and when combined with a flatter bar, it gives the R a sportier riding position than the old Duke. That bar moves the grips 21 mm forward and 10 mm down, and the footpegs are 12 mm higher and 33 mm further back. That sounds like a lot, but the riding position still feels very familiar and is totally usable for off-track duties in the real world, so don’t stress on that front. They haven’t overdone it.

Excellent feeling and feedback from that amazing front-end. Just a delight to steer

I think I’d need to ride the old and new models back-to-back to really appreciate the difference, with a new track to learn thrown into the mix as well, but it certainly didn’t feel overly firm or sporty compared to my own bike. It felt very familiar. Just ‘a little more’ than the old model. And the Duke still comes in at a wet, fully fuelled weight of 190 kg, which is excellent considering the amount of electronic wizardry on modern bikes.

Is it better than my old Duke?

Yes. (Dammit). This could be dangerous for my wallet. While still feeling very, very much a Duke first and foremost, I am now in a bit of a pickle. The R is noticeably better. On track, it was an absolute delight. On the road, I was constantly looking for the next opportunity for shenanigans.

Very planted, very accurate. Hitting your lines doesn’t get much easier…

Sydney Motorsport Park, as it turns out, is a particularly technical circuit. For a newcomer like me, it certainly seemed that every single damn corner needed a late apex. A couple had a double apex. And nearly every single one had at least one decent bump mid-corner.

The Duke was the perfect bike for learning a new circuit. That front end that I loved on the old bike seemed even more millimetre-perfect. Line choice felt as if it were done by thought alone. Want to tighten the line up? Sure thing. That big bump mid corner? Yeah, don’t worry about that. Overcooked it a bit coming into that corner? No stress, just trail those brakes a bit deeper.

The new Duke R is a step up from the outgoing Duke 990.
Slightly more focussed riding position improves the ride on both road and track

And on its side, on those outstanding OEM Michelin Pilot Cup 2 tyres? Utterly composed. I was lucky enough to be led around for a lap or two by a fellow journo who knew the track well (thanks, Dave!), and within two laps, confidence was already ramping up.

By the third session, I dialled back the TC to setting 6 (with 9 being the least intervention) and realised that where I’d been getting ‘okay’ drive out of corners earlier on setting 3, it had actually been holding things back a little, smoothing everything out. Setting 6 took it to another level. More drive. More speed. More feeling from that rear end. Only the slightest wriggle as things hooked up. So. Much. Fun.

The Duke R was the perfect bike to learn SMSP’s technical layout

The Duke is incredibly user-friendly and accessible. SMSP (I admit to still referring to it as Eastern Creek) is a tricky circuit, and we weren’t exactly hanging about. But I didn’t have a single moment all day.

The RC R is much more than just a Duke with fairings

If I have one message for you, it is that the RC R is a seriously capable sportsbike (it is eligible for the NextGen Supersport category, after all). Geometry and ride feel are quite different to the Duke R; everything about it is sportier and designed with performance in mind. On top of that, it looks damn good.

The RC R in the dark metallic scheme is quite striking in the metal, with a metallic paint finish hard to replicate in photos

The fairing and bodywork are clearly the first and most obvious differences. Nicely proportioned, with more than a smattering of a certain RC16 MotoGP bike worked into the styling package. ‘Downforce optimised’ front wings and the rear deflector (in front of the rear tyre) join the elevated pillion seat for a look that is positively GP-esque. I put the pillion seat in italics simply because I’m not sure how practical that seat would be in practice. But if your missus fits on that, more power to ya.

Or of course there is the orange colour scheme if you want maximum RC16 vibes…

The ride position is noticeably more focused. Your hands are lower and further forward via new triple clamps and clip-on bars. The footpegs sit higher and further back on adjustable rearsets that can be moved between ‘Street’ and ‘Track’ positions. Track places the pegs back 25 mm and up 17 mm compared to Street – a noticeable change. Topping off the more aggressive rider triangle is the firmer seat, which sits 5 mm higher at 845 mm. Still plenty low enough to comfortably get both feet on the ground, though.

Good luck getting your missus on that pillion seat…

In addition to different triple clamps, bars, and rearsets, a quick scan of two side-by-side pics shows that, compared to the Duke, the fuel tank, seat, subframe, exhaust, and swingarm are also new. You might also notice a steering damper on the RC R.

The truly eagle-eyed might even notice that the RC R runs Brembo’s top-of-the-pops Hypure calipers and the Duke makes do with Stylemas. ‘Makes do’. Hard to imagine anyone ever actually needing more than Stylemas, considering that up until a couple of years back, they were arguably the best stoppers us mortals could get our mitts on, until Brembo released these new Hypure jobbies. Let’s just say Duke R riders aren’t underbraked…

Front to back weight is excellent (and you can see those Hypure callipers here)

That tank has been stretched to fit the new rider triangle and designed specifically with contact points in mind. It’s probably not as sculpted as I’d personally prefer, but it offers ample contact on the outside knee during cornering and actually accommodates almost a litre more fuel than the Duke tank – at 15.7 L compared to the Duke’s 14.8 L.

All of the additional fairing and tank work adds another 5 kilos to the wet weight over the Duke R, bringing the RC R tally to 195 kg. Interestingly, the front-rear bias sits at 52.5 front and 47.5 rear, which – as I’ll touch on later – is exceptional.

The RC R also gets a unique exhaust setup with a little more bark and pop than the Duke R

Speaking of weight, the rear subframe shaves 400 grams off the Duke variant and has air intakes integrated directly into the construction, along with that very trick-looking aero work under and around the pillion seat.

If you’re really, really paying attention, you might notice that the Apex Pro suspension used on the RC R has ever so slightly shorter travel (at 130 mm on the front and rear compared to the 143 mm on the front of the Duke R and 140 mm on the rear). And that the bike sits nearly 50 mm lower in terms of ground clearance (that difference is exaggerated, given the RC R has a lower fairing).

Here’s a nice road shot showing the lower rear deflector just in front of the rear tyre

You can’t see that the airbox is new. Or that the engine mapping, ABS and TC tuning is unique. All that is to highlight just how different the bike is, despite sharing a motor and chassis.

They’ve nailed the balance

On the track, the difference was noticeable from the very first corner. While the Duke R is even more eager and easy to throw into corners than the old Duke, the RC R is on another level. It’s not just that it steers with less input (helped by a ~1 degree steeper head angle than the Duke R), or that it feels even more planted on its side. It’s the way it rotates underneath you that is special.

The RC R pivots along a central line thanks to excellent balance and mass centralisation

Whereas the Duke R feels relatively traditional – as though it is pivoting onto its side from the bottom of the tyre (as you’d expect), the RC R feels like it’s pivoting around a central line running through the bike from front to back. In the corners, it feels damn near weightless when changing direction. I’ve only felt this on a select few bikes that had exceptional balance. The BMW K 1300 R was the first bike I felt that on, incidentally, and that was an astonishingly good bike to ride.

This near-weightless agility is precisely what engineers chase when they talk about mass centralisation. And we hear it all the time in marketing guff. But only very, very occasionally can you actually feel it. The RC R is one of those cases.

Damn near perfectly balanced, the RC R is on another level in terms of the way it rotates underneath you

It’s difficult to explain, but allow me to create a mental image for you. Imagine a line running through the middle of the bike from front to back, perpendicular to the ground. The line runs through the bike, entering the front at a height aligned somewhere around the top of the front rim, running through the engine and out through the back at the top of the rear rim. That line is roughly where it feels like this bike pivots around when tipping into corners.

It’s just wonderfully balanced. The RC R rotates around the line beneath you. Most bikes feel like they rotate from the bottom of the tyres.

And it’s just as effortless to tip in on the road…

On the track, compared to the Duke, you are quickly aware of the RC R’s higher limits – that there is noticeably more you can push. I was also quickly aware that I had to work harder to find them. Body position is more important to get right in order to exploit the extra available performance. But when you do the work, you’re justly rewarded.

In the afternoon, we did a road loop on both bikes, and the Duke was as good as I expected. Comfortable, easy to ride, that great dash and turn-by-turn navigation display really impresses. No surprises there. What was surprising was how manageable the RC R’s more focused riding position was on the road.

And even though the riding position is noticeably more aggressive than the Duke R, it’s still very manageable on the road

I thought it would be hard work. The seat is certainly noticeably firmer, but it was far better than I’d imagined it was going to be. It’s not all good news, though. Two negatives did emerge on the road that you won’t notice at the track. The steering lock is noticeably reduced on the RC R and could be problematic when filtering and manoeuvring through traffic. And that great touchscreen dash is a little harder to reach and use because it’s nestled more snugly behind the windscreen. Fairly small issues in the grand scheme of things.

Final thoughts

Ultimately, both of the 990 offerings are exceptional. One is noticeably more focussed and looks a little like the MotoGP bike; the other is a naked weapon with a more accessible upright riding position. Choose your poison.

Choose your poison. I’d still go for the Duke R for the mix of riding I do, but if I did more track days…

Available right now – the Duke will set you back 23,990, and the RC R another grand on top of that. You will want the optional Tech Pack for all the fruit (Wheelie Control, Custom modes, Track Mode, Lap Timing, Telemetry, Map Selection, TC adjustment, Launch Control, Quickshifter, Cruise Control, Adaptive brake light and MSR adjustment), which will add another $1650 on top of the base price. And frankly, you’d be barking mad not to tick that box.

KTM provides its Four-Year Premium Warranty coverage on these bikes as standard.

I foresee a conversation with the minister of finance at Casa Del Vicko…

For me? I’ll be trying to get one of the Dukes we rode on the launch into my shed to ride back-to-back with my own bike for an upcoming Duke Diary video. And I suspect I’ll be making a decision that the minister for finance might not be happy about…

It’s only money, right?

KTM Duke 990 R strengths

• Super accessible, confidence-inspiring handling for any road or track.
• That LC8c engine is punchy and just downright fun.
• Comfortable riding position despite being sportier than the old model.
• Great touchscreen dash and updated tech abounds.

KTM Duke 990 R weaknesses

• Tech pack is basically mandatory if you want the goodies. And you do.
• Not for those who want to blend in.
• Maybe not for those without a level of self-control. Or a lot of license points.

KTM 990 RC R Strengths

• NextGen supersport capability.
• Astonishingly good balance and that central pivot turn in.
• Looks not unlike an RC16.

KTM 990 RC R Weaknesses

• Reduced steering lock and a firm seat are a compromise around town, but manageable.
• A more focussed rider triangle is exactly that for longer road rides.
• Tech pack needed here too….

Which bike for whom?

• Duke R for daily duty, do-it-all, some touring and track days as well.
• RC R, if you will be doing regular track days and weekend scratching, and are okay with a little compromise in terms of comfort.
• Both? If you have a very understanding partner and a big shed 🙂
