2026 KTM 690 SMC R Review | Brilliant, brutal but hard to justify…

2026 KTM 690 SMC R Review

I’m a huge supermoto convert. It is the one form of motorcycling in which I feel most at home.

Somewhere between my very average motocross skills and my questionably competent road-racing ability, supermoto is the discipline that makes me feel like perhaps I’m not quite as hopeless a rider as I sometimes suspect.

A lot of that confidence comes from years spent aboard my trusty Husqvarna FS 450, but the 2026 KTM 690 SMC R is a very different animal. I’ve had the SMC R sitting in my garage for the past month, and every time I swing a leg over it, I find myself asking the same question.

Who, exactly, is this bike built for?

That’s not intended as a lazy throwaway line. It’s the central question with the 690 SMC R, because this is a motorcycle with a very narrow brief and very little interest in pretending otherwise.

KTM’s big supermoto is powered by one of the largest single-cylinder engines fitted to any production road bike. That means a lot of piston, a lot of thump, and a riding experience that still feels unlike almost anything else available with indicators and a numberplate.

The 692.7 cc LC4 single now produces a claimed 79 PS and 73 Nm, or about 58 kW in more familiar Australian numbers. That makes it a brutally strong single-cylinder engine by any normal measure, and there is an immediacy to its delivery that few twins, let alone triples or fours, can replicate.

The flipside is that a piston of this size will never feel like a turbine.

Even with the dual balancer shafts KTM introduced several generations ago, the 690’s motor remains vibey and fairly single-minded. It is not especially smooth in the way it generates power, nor is it particularly enjoyable when you’re holding it high in the rev range for any length of time.

There is still enough vibration to constantly remind you what you are riding. That said, most of the truly excessive tingling that once defined big-bore thumpers has been engineered out, and that is no small feat given the basic ingredients involved.

So perhaps I am being a bit harsh.

After all, KTM has traditionally had no trouble shifting the 690 Enduro R, which uses the same basic LC4 platform, and I’m told the SMC R does not exactly sit around gathering dust on showroom floors either.

Clearly, there are plenty of riders who understand this thing better than I do. Or perhaps they are simply younger, sillier and more willing to have their licence surgically removed.

The big LC4 gets a proper going-over

Although the 2026 engine retains the familiar LC4 architecture, KTM has given the platform one of its more substantial revisions in recent years.

The crankcases are new, along with revised clutch and stator covers, an updated oil circuit and improved internal oil routing. The aim is better lubrication, better durability and cleaner running without taking away the big single’s trademark hit.

There’s also revised valve timing, updated mapping and a higher-pressure fuel pump, all working with KTM’s latest ride-by-wire calibration. The result is a throttle that is cleaner and more controlled than before, even if the SMC R still does not much enjoy being ridden half-heartedly.

Around town the engine pulls from low rpm with real authority, but it doesn’t reward dawdling. The SMC R wants a proper right hand. Anything less and it gives the distinct impression it is laughing at you from somewhere beneath the tank.

This is not a bike that loves being short-shifted through suburbia while you ponder groceries and traffic lights. It wants to be grabbed by the scruff of the neck.

That is, of course, part of the appeal.

There are three standard ride modes: Rain, Street and Sport. I’m not going to spend paragraphs explaining the subtle differences in throttle response, because I have been writing that sort of thing for nearly 20 years and we all have better things to do.

Stick it in Sport and get on with it.

Or, if you want the SMC R to show more of its real personality, get the optional Tech Pack and unlock Track mode. Then you can start properly playing with the electronic safety net rather than just riding around with KTM’s lawyers watching over your shoulder.

Unlike some big singles, the 690 runs a six-speed gearbox, with sixth acting as something of an overdrive. That drops the revs enough to make freeway riding less buzzy than you might expect, although “less buzzy than expected” is not the same thing as relaxed.

Acceleration from slow and medium-speed corners is very strong. The engine picks the bike up and hurls it forward with the sort of mechanical urgency that makes you laugh inside your helmet.

At times, though, the delivery still feels a little jackhammer-like. It is forceful, entertaining and occasionally hilarious, but it is not what I’d call broad or especially nuanced.

And that leads to the central problem I have with the SMC R.

It is riotously good at one particular thing, but that one thing is not how most of us spend most of our time on a motorcycle.

Brilliant when the road gets silly

The 2026 690 SMC R retains fully adjustable WP Apex suspension at both ends, with revised damping settings aimed at improving both comfort and control.

I haven’t spent enough time on the previous generation to give you a meaningful back-to-back comparison, but there is certainly nothing wrong with the latest bike’s agility once the road starts tying itself in knots.

This is where the KTM makes perfect sense.

The tall 899 mm seat, generous 237 mm of ground clearance and 17-inch wheels give the SMC R the sort of stance and leverage that make supermoto riding so addictive. Continental ContiAttack SM 2 tyres replace the previous Maxxis rubber, and the KTM feels absolutely at home when you are flicking it from one side of the tyre to the other.

On a tight back road, the thing is a weapon.

Feet-out, supermoto-style road riding does not get much better than this. The SMC R is light, narrow, direct and immediate. It does not ask for big inputs, and it does not require a lot of road to be fun.

That is a big part of its charm.

At a claimed 152 kg without fuel, or 162 kg with its 13.3-litre tank filled, the 690 feels like a bicycle compared with most full-sized road bikes. There are plenty of more powerful motorcycles that will belt it on a fast road, but below about 110 km/h, on the right stretch of tight, nasty, second-and-third-gear tarmac, very few things will disappear from a well-ridden SMC R.

That is the magic of supermoto.

It turns ugly little roads into playgrounds. Roads that feel too tight or too bumpy on a superbike suddenly feel perfect. The KTM skips, darts, pivots and drives with an enthusiasm that makes most conventional road bikes feel a bit too serious.

Unfortunately, life is not just a series of perfect mountain passes.

You eventually have to ride through towns, sit in traffic, cruise along straight bits, and deal with the boring transport stages between the fun stuff.

That is where the 690 starts to lose me.

The uncomfortable truth

The SMC R is fun, exciting and full of character, but it only truly makes sense to me when I’m riding it in a way that would not impress the local constabulary.

That is a problem.

At lower speeds, the engine’s vibration and big-single character are always present. The throttle response is much improved, but the bike still wants commitment. It does not have the easy, creamy bottom-end delivery of a good twin, and it does not have the relaxed roll-on flexibility that makes a conventional nakedbike pleasant in everyday use.

Then there is the seat.

The SMC R’s off-road-style perch is narrow, tall and firm. It gives you room to move when you are attacking a road, which is exactly what it should do, but comfort is not high on the list of priorities. Anything beyond about half an hour and you become increasingly aware that this motorcycle was not designed by someone who spends much time thinking about Sunday coffee runs.

You don’t sit in the SMC R so much as perch on top of it, waiting for an excuse to misbehave.

That’s great when the road is right. Less so when it isn’t.

KTM says the ergonomics are designed to allow freedom of movement between fast corners, casual commuting and the odd dirt section. Technically, that may be true, but the SMC R’s idea of a casual commute is very different to mine.

Proper brakes, proper electronics

There is no issue with the braking hardware.

The front end uses a Brembo radial master-cylinder and a Brembo M 4.32 monobloc four-piston caliper biting on a 320 mm front disc. The rear runs a 240 mm disc, and both ends are tied into KTM’s latest ABS systems.

The front brake has plenty of power and good feel. It is direct without being wooden, and strong without being grabby. The ABS intervention is well judged and does not get in the way under normal hard road use.

The rear brake is also genuinely useful rather than just being something fitted to satisfy the ADR paperwork. It gives enough feel to trail pressure into corners, settle the chassis, or indulge the occasional Chris Fillmore fantasy if you have the talent and the space.

The 690 also receives a decent electronics package.

Cornering ABS, Supermoto ABS and lean-angle-sensitive Motorcycle Traction Control are standard, while the optional Tech Pack adds Quickshifter+, Motor Slip Regulation, multi-stage slip adjustment, adjustable wheelie control and Track mode.

The SMC R’s electronics do not feel like they have been fitted to domesticate the bike. They are there to let you push harder while keeping the whole thing from becoming a YouTube compilation.

That is the right approach for this type of motorcycle.

The new 4.2-inch TFT display is also a big step forward over the old monochrome LCD unit. It is slim, clear and nicely integrated, with redesigned switchgear that makes menu navigation easier than before.

KTM has been better than most manufacturers at making electronic adjustment visually understandable. The little graphics showing the bike sliding further as traction control is reduced, or the front wheel lifting higher as wheelie control is wound back, are simple but effective.

That might sound like a small thing, but it matters. The best electronics in the world are useless if the rider has no intuitive sense of what they are changing.

Bluetooth connectivity through KTMConnect and a USB-C charging port also drag the SMC R closer to KTM’s latest nakedbike range. You can make calls, access music, use turn-by-turn navigation and keep your phone charged, should you wish to bring a small amount of civilisation into what is otherwise a fairly uncivilised motorcycle.

A better bike, but not a broader one

The 2026 KTM 690 SMC R is clearly more refined than big singles of old.

The engine is stronger, cleaner and less agricultural. The electronics are better. The display is better. The suspension has been updated. The brakes are excellent. The chassis remains as sharp and playful as ever.

But I’m not convinced it is significantly broader in its appeal.

The SMC R remains a specialist. A very good specialist, yes, but a specialist all the same.

It is not a do-it-all nakedbike. It is not a comfortable commuter. It is not a weekend tourer. It is not a sensible second bike, unless your idea of sensible involves backing it into roundabouts while pretending you’re on a kart track.

What it is, is a supermoto with road registration and just enough modern electronics to make the lunacy feel slightly more sophisticated.

That will be enough for some riders.

For them, the SMC R will make perfect sense. They will look at the big single, the 17-inch wheels, the Brembos, the WP suspension and the KTM badge and see exactly what they want. Nothing else will scratch the same itch.

I understand that. I really do.

The problem is that I also understand the SMC R well enough to know I’m probably not the rider KTM had in mind.

Maybe if I were 10 years younger, I’d be more willing to put up with its compromises. Maybe I’d be happier ignoring the seat, the vibes, the narrow use case and the price because the bike made me laugh every time I rode it hard.

But even when I squint and try to convince myself I’m still the same idiot hooligan I was when I started this job nearly 20 years ago, I can’t quite get there.

Then there is the price

The 2026 KTM 690 SMC R is listed in Australia at $21,195 ride-away.

That is a lot of money for a single-cylinder road bike.

Yes, it is an advanced single. Yes, it has proper suspension, proper brakes and a proper electronics package. Yes, it delivers a riding experience that very few motorcycles can match.

But $21,195 is still a serious ask for something so focussed.

KTM’s own 990 Duke is only a few thousand dollars further up the road, and that bike offers substantially more power, much greater flexibility and the ability to attack a good road while also being far easier to live with the rest of the time.

I know that’s not a perfect apples-with-apples comparison. The SMC R is not trying to be a 990 Duke. It is not trying to be an all-round nakedbike. It is not trying to make sense to everyone.

But price still matters.

At this money, the buyer really needs to want the supermoto experience above all else. Not just a light, fun road bike. Not just something different. Not just a KTM with attitude.

You need to specifically want this.

Verdict

I wanted to love the 690 SMC R more than I did.

As a supermoto tragic, that leaves me a little sad.

There is a brilliant motorcycle in here, but it is brilliant in a very specific way. On the right road, in the right mood, with the right amount of commitment, the SMC R is an absolute riot. It is sharp, fast, light, mischievous and properly alive.

The trouble is that the rest of the time it asks you to put up with quite a lot.

It is vibey. It is uncomfortable. It is not especially relaxed around town. It feels happiest when you are riding in a manner that is, at best, difficult to justify in polite company.

For the rider who knows exactly what they are buying, none of this will matter. They will accept the compromises because the payoff is worth it.

For everyone else, the 690 SMC R might be one of those bikes you admire more than you actually want to own.

I’m clearly not the target customer. KTM will not care, and nor should it. There are still enough riders out there who want a big-bore supermoto with a licence plate and no interest in growing up.

For them, the 690 SMC R remains the king of its peculiar little kingdom.

For me, it’s a pass this time.

And I hate that a bit.
