Introduction
KTM has a real, obvious gap in its motorcycle lineup, and everyone’s known about it for years. Walk into a KTM showroom today, and you’ll find the 390 Duke, making around 43 horsepower, sitting right next to the 790 Duke, which makes more than double that at around 95 horsepower. That’s a huge jump with nothing in between — and that’s exactly the gap a new twin-cylinder motorcycle has been rumoured to fill for a long time.
New spy shots from Europe have now given us our clearest look yet at what could be that bike. But here’s the twist worth knowing before you get too excited: not everyone agrees on what this test bike actually is. Let’s walk through what’s genuinely confirmed, and where the story gets murky.
Key Highlights
- A KTM test motorcycle, believed to be the upcoming 490 Duke, has been spied testing on public roads in Europe.
- The bike uses a tubular steel trellis frame with the engine as a stressed member, a banana-style swingarm, and what looks like a production-ready exhaust system.
- It’s expected to use a twin-cylinder engine, just under 500cc, producing somewhere between 55 and 65 bhp — a genuine step up from the 390 Duke’s single-cylinder unit.
- BikeWale’s own reporting disagrees with several other outlets on one key point: whether this specific engine is actually the “gap-filling” 490 Duke motor, or a completely different twin-cylinder project meant to replace KTM’s older 690 single-cylinder platform.
- Sources also disagree on the timeline — some reports point to an EICMA 2026 debut with an early 2027 India launch, while the most recent report suggests a later EICMA 2027 debut with an early 2028 launch.
- The bike is expected to be built in India by Bajaj Auto at its plant near Pune, and will likely spawn related models like the 490 Adventure and a possible RC 490.
What the Spy Shots Actually Show
Let’s start with what’s genuinely visible in the photos, since this part isn’t in dispute across any source. The test motorcycle is clearly in an early development stage — most of the bodywork is unfinished, and KTM has even borrowed the headlamp, instrument cluster, and mirrors from the existing 390 Duke just to get the prototype running on public roads.
But a few genuinely production-ready details stand out. The bike sits on a tubular steel trellis frame, using the engine itself as a stressed structural member — a classic KTM approach. Interestingly, it appears to drop the composite subframe used on the 390 Duke in favour of a simpler, bolt-on trellis subframe. It also gets a distinctive banana-shaped swingarm, with the catalytic converter tucked neatly underneath it, plus in-house WP radial brake calipers, a radial brake master cylinder, single discs front and rear, and 17-inch alloy wheels at both ends. The exhaust system in particular looks close to a finished, production-ready design, even though the bodywork around it clearly isn’t.
The Genuine Disagreement: Is This Really the “490 Duke”?
Here’s the part of this story that most other coverage skips over, and it’s genuinely worth your attention. Most outlets reporting on twin-cylinder KTM spy shots this year have described a fairly simple, consistent story: KTM is building a new parallel-twin platform to sit between the 390 and 790 Dukes, and this is that bike.
BikeWale’s own reporting on this specific set of spy shots pushes back on that assumption. According to their coverage, this engine looks different from the one seen on earlier test mules — and they believe this particular twin-cylinder motor is more likely a replacement for KTM’s older 690 single-cylinder platform, not the same “gap-filling 490 Duke” engine that’s been widely discussed elsewhere. Their reasoning comes down to a genuine technical detail: the engine casings and cylinder head design look noticeably different between this test mule and the ones spotted earlier in the year.
This matters more than it might seem. If BikeWale’s theory is correct, KTM may actually be developing two separate twin-cylinder projects at once — a smaller, India-focused twin built by Bajaj for the 390-to-790 gap, and a separate, possibly larger-displacement global twin meant to eventually replace the ageing 690 single. Interestingly, at least one other source we checked, iamabiker, independently describes something similar: a smaller A2-licence-friendly 490 Duke project alongside a separate “middleweight 650-750cc twin” also spotted testing in Europe — which lines up reasonably well with BikeWale’s theory, even though neither source directly references the other.
Our honest take: until KTM says something official, treat “this is definitely the 490 Duke” as one theory, not a confirmed fact. BikeWale’s dissenting view is genuinely plausible and worth taking seriously.
Engine Expectations: What’s Widely Agreed
Setting aside exactly which project this specific test mule belongs to, there’s strong, repeated agreement across nearly every source on the broader engine expectations. KTM is working on a new parallel-twin engine platform, somewhere around 490cc, likely using a 270-degree crankshaft similar to the setup on KTM’s bigger twin-cylinder motorcycles. Expected output sits in the 55 to 65 bhp range, with a lower-powered, A2-licence-compliant version capped at or under 48 bhp for European markets with power restrictions for newer riders.
What’s Expected vs What’s Confirmed — At a Glance
| Detail | Status |
|---|---|
| Twin-cylinder engine, under 500cc | Widely reported across sources |
| 55-65 bhp expected output | Widely reported, not officially confirmed |
| 270-degree crankshaft | Reported by BikeWale specifically |
| A2-compliant lower-power version | Reported by BikeWale specifically |
| This exact engine = “the” 490 Duke motor | Disputed — BikeWale disagrees with other outlets |
| Built by Bajaj in Pune | Widely reported across sources |
| Trellis frame, WP brakes, 17-inch wheels | Confirmed via spy shots |
When Will It Actually Launch? Sources Don’t Fully Agree
This is the second genuine discrepancy worth flagging honestly, rather than picking whichever date sounds cleanest. Several sources — RushLane, MotorBeam, Cartoq, and MSN/NDTV, all published back in May 2026 — describe a debut at EICMA 2026, with an India launch expected in early 2027.
BikeWale’s report, which is both the most recent (published August 28, 2026) and the source you specifically asked about, tells a different story: it expects the bike to be shown to the public toward the end of 2027, likely debuting at EICMA 2027, with a market launch in early 2028 — a full year later than what the earlier reports suggested.
Since BikeWale’s account is both more recent and more specific about why the timeline has shifted (tying it to this being a still-early, unfinished prototype), we’d lean toward trusting the later timeline as the more current, accurate expectation. But it’s genuinely possible the earlier reports were describing a different, more advanced twin-cylinder project altogether — which would tie back neatly to the same “there might be two different bikes here” confusion covered above.
Who Else Will Use This Platform?
Regardless of exactly which twin-cylinder project ends up being called the “490 Duke,” there’s good agreement that this general engine platform won’t be limited to a single motorcycle. BikeWale specifically mentions this twin engine is also expected to power a KTM 490 Adventure, and possibly a race-focused RC 490, aimed at competing with bikes like the Aprilia RS 457 and the Kawasaki Ninja 500. Other sources independently confirm a 490 Adventure has also been spotted testing separately, reinforcing that KTM is genuinely building out a small family of twin-cylinder middleweight bikes, not just one standalone model.
Why This Bike Matters for KTM
Whichever version of this story turns out to be accurate, the underlying reason KTM is doing this is clear and widely agreed upon: the gap between the 390 Duke’s roughly 43 hp and the 790 Duke’s roughly 95 hp is genuinely large, and KTM is leaving real sales on the table by not having anything in between. A twin-cylinder engine in the 55-65 hp range would also give KTM a smoother, more refined alternative to its single-cylinder “thumper” engines — genuinely useful as global emission rules get stricter and manufacturers look for cleaner ways to deliver strong performance.
With Bajaj expected to build the bike in India, there’s also a reasonable chance this could arrive at a genuinely competitive price for the Indian market, continuing the successful playbook that’s already made the 390 range one of KTM’s strongest sellers here.
FAQs
1. Has KTM officially confirmed the 490 Duke?
No. Everything about this motorcycle, including its name, exact displacement, and specifications, comes from spy shots and informed speculation — KTM has not made an official statement.
2. Is this spy-shot test mule definitely the 490 Duke?
This is genuinely disputed. Most outlets assume so, but BikeWale’s own reporting suggests this specific engine might actually belong to a separate project meant to replace KTM’s older 690 single-cylinder platform, based on differences in the engine casing and cylinder head design.
3. What engine will the KTM 490 Duke use?
It’s widely expected to use a new parallel-twin engine, just under 500cc, producing somewhere between 55 and 65 bhp, though this isn’t officially confirmed.
4. When will the KTM 490 Duke launch?
This is unclear. Some earlier reports suggested an EICMA 2026 debut with an early 2027 launch, while the most recent report suggests a later EICMA 2027 debut with an early 2028 launch.
5. Where will the KTM 490 Duke be manufactured?
It’s expected to be built in India by Bajaj Auto at its plant near Pune, similar to how KTM’s current 390 range is manufactured.
6. Will there be other bikes based on this same engine?
Yes, most likely. Reports point to a related KTM 490 Adventure, and possibly a race-focused RC 490 aimed at rivals like the Aprilia RS 457 and Kawasaki Ninja 500.
7. What is the expected price of the KTM 490 Duke?
BikeWale’s own listing shows an estimated starting price of around Rs 3.80 lakh, though this is an early placeholder estimate, not an official figure.
8. Why is there so much confusion around this bike’s identity?
KTM appears to be developing more than one twin-cylinder project at once — a smaller, India-focused twin for the gap between the 390 and 790 Dukes, and possibly a separate, larger twin-cylinder platform for global markets. Different spy shots may be capturing different projects, which explains the conflicting reports.
Conclusion
The KTM 490 Duke story is a genuinely useful reminder that not every “confirmed” detail in spy-shot coverage is actually settled. What’s real and consistent across every source: KTM is working on a twin-cylinder engine to fill the obvious gap in its Duke lineup, and Bajaj will likely build it in India. What’s genuinely still unclear is whether this exact European test mule is that bike, or a related-but-different project — and exactly when it’ll actually reach showrooms. Until KTM makes an official statement, our honest advice is to enjoy the spy shots for what they are: a genuinely exciting glimpse of KTM’s future, wrapped in a bit of real, honest uncertainty about the details.
