BMW Motorrad appears to have the missing GS in development: a twin-cylinder road enduro positioned between the F 450 GS and the F 900 GS, with a 21-inch front wheel and displacement of around 600 cm³. The first images of a test mule, published by the German press in August 2026, show a motorcycle that is already fairly well defined, although it still lacks its final bodywork.

However, it is important to consider how this news should be interpreted. BMW has presented nothing, confirmed no technical data, and announced neither a name nor a date. What follows is therefore an analysis: what is certain, what is reasonably likely, and what remains pure speculation. This distinction matters more than usual in this case, because highly detailed technical specifications for this prototype are already circulating, although no one has verified them yet.

What the prototype shows, and where the news comes from

The spy photos were taken during road testing and were picked up in Italy by several publications starting in mid-August 2026. The primary source is the German magazine Motorrad, historically one of the most reliable sources when it comes to BMW test mules, since testing largely takes place in Bavaria and on Alpine passes.

Detail of the parallel twin and the spoked front wheel of the BMW prototype undergoing testing
The test mule undergoing testing: upside-down fork, spoked wheels, and a provisional exhaust.

Several details can be made out from the images with reasonable certainty. The front end has an X-shaped LED light signature, clearly derived from the styling language introduced by the R 1300 GS. The front beak, an identifying feature of Munich's enduro models, is missing: this may be a styling choice, but on a test mule it is equally plausible that it is simply a part that has not yet been fitted. The front wheel is 21 inches. The front braking system has dual discs. The swingarm is aluminum, and the monoshock is mounted laterally, using a solution reminiscent of the F 450 GS.

On the frame, the readings differ slightly: some analyses place it closer to the steel frame of the F 900 GS than to that of its smaller sibling. If confirmed, this detail would say a great deal about the bike's positioning, because it would mean BMW is not simply enlarging the 450 platform but is building something intermediate at the chassis level too.

What BMW has actually said is more limited, but not insignificant. Markus Flasch, CEO of BMW Motorrad, had already explained at the presentation of the F 450 GS concept that a family of models would be built around that new twin-cylinder architecture, and that the GS would not remain alone. At EICMA 2025, speaking about the segments in which the brand operates, he specifically pointed to the range between 450 and 900 cc. None of these statements announces an F 600 GS. Both, however, make the hypothesis consistent with the company's stated strategy.

The gap in the range: €7,000 and 41 kilos

To understand why this motorcycle would make sense, no inside information is needed: just look at BMW's current price list.

The F 450 GS is an A2-licence motorcycle: a 420 cc parallel twin producing 48 hp at 8,750 rpm and 43 Nm at 6,750 rpm, weighing 178 kg in running order, with 19- and 17-inch wheels and a starting price of €7,590. It is light and easy to handle, designed for everyday use and light off-road riding.

The F 900 GS is in another category: 895 cc, 105 hp, 219 kg in running order, 21- and 17-inch wheels, and a price of €14,600. It is a serious motorcycle, capable off-road and demanding when it comes to handling it at low speed or on difficult surfaces.

There are 41 kilos, 57 hp and around €7,000 between the two. That's a huge gap, and not just on paper. It is exactly the space where most of today's European adventure market sits: the rider who has moved beyond the A2 phase, wants a proper motorcycle for touring and riding off-road, but does not need—or does not want to manage—220 kilos and 100 horsepower.

There is also a licensing issue. The F 450 GS is designed for the A2 licence and remains so. A 65–70 hp motorcycle, on the other hand, can easily fall within the limits for restriction to 35 kW and then be derestricted: it could therefore also be purchased by someone who still has an A2 licence, with the prospect of keeping it afterward. That is no small commercial advantage, and Yamaha has been exploiting the same strategy for years with the restricted version of the Ténéré 700.

The engine: is Norton's 585 really the same?

A clarification is needed here, because several reports have simplified things a little too much.

The reasoning circulating is this: BMW produces the F 450 GS in India together with its partner TVS; TVS owns Norton; Norton has just launched the Atlas with a 585 cc, 70 hp parallel-twin engine; therefore, the future mid-size GS would use that engine. The premises are all true, but the conclusion is a leap.

135 degrees versus 270: why the detail matters

The F 450 GS’s twin-cylinder engine has a 135-degree crank, an unusual solution BMW chose to achieve smooth low-rpm power delivery and a distinctive exhaust note. The Norton Atlas’s 585, on the other hand, has a 270-degree crankshaft, the classic layout of modern parallel twins, from the Ténéré to the Transalp. They are two different architectures with different characteristics.

Externally, the two engines look similar — those who have examined them closely have noted very similar mounts and covers — and both come out of the TVS plant in Hosur. But saying they are the same engine is imprecise. It is more accurate to say that they belong to the same industrial family and that BMW, if it wants to increase displacement, already has practical proof that this architecture can handle 585–600 cc and 70 hp.

If BMW retains its 135° firing order, as seems reasonable to avoid altering the character of the project, the result would be an engine related to, but not identical to, the Norton engine. At present, there is no confirmation in either direction.

What 65–70 hp Would Really Mean

Reports indicate a displacement between 585 and 600 cc and power between 65 and 70 hp. Some sources go into more detail, mentioning 590 cc and 65 hp, but these are figures from journalistic sources, not official specifications.

Taken at face value, those figures would place the motorcycle just below the Ténéré 700 (73.4 hp) and well below the Transalp (92 hp) and V-Strom 800DE (84 hp). That is not necessarily a disadvantage: in this category, peak power matters little, and a motorcycle built around mid-range torque, with low fuel consumption and controlled weight, is often more effective than one with a richer specification sheet. It is, after all, the same philosophy that made the Ténéré 700 a benchmark despite being, on paper, the least powerful of its rivals.

21 up front, 18 at the rear. Or 17?

The 21-inch front wheel is the most significant element of the whole story because it is a statement of intent. Anyone fitting a 21-inch front wheel is not building a crossover: they are building a motorcycle that has to work off-road.

A 21-inch rim paired with a high-profile tire absorbs obstacles better, does not get hung up on rocks and steps, and maintains a more stable line on loose surfaces. The price is paid on asphalt: slower steering, less precision in fast corners, and greater sensitivity to road ruts. It is the compromise accepted by the Ténéré 700, the Tuareg 660, and the F 900 GS itself.

The Rear Question

Regarding the rear wheel, sources do not agree, and it is right to say so clearly instead of choosing the most convenient figure.

Several Italian publications mention an 18-inch wheel, which would be consistent with the off-road setup and align the bike with the Ténéré 700. Other reconstructions, based on readings of the same images, indicate a 150/70-17, the solution adopted by the F 900 GS, without ruling out the 18". It is normal for test bikes to be tried with both configurations.

The difference is not cosmetic. The 18" rear broadens the choice of serious knobby tires enormously and improves the rim's resistance to impacts; the 17" offers a wider choice of road tires, lower costs, and more natural behavior on asphalt. Until BMW says otherwise, this detail remains unresolved.

The rest of the chassis

Available indications point to upside-down forks, travel of around 200 mm, a seat height in the 850–900 mm range, and a kerb weight below 200 kg. The twin front discs, if confirmed, would be a clear step up from the F 450 GS's single disc and would be consistent with a higher top speed. There is also talk of the Easy Ride Clutch automated clutch, already available on the 450 in Trophy trim, but none of these details has been officially announced.

BMW versus Yamaha Ténéré 700

The Ténéré 700 is the natural benchmark, and not out of journalistic laziness. It is the bike that defined the category: a steel double-cradle frame, 21- and 18-inch wheels, deliberately minimalist electronics, a 689 cc CP2 engine producing 73.4 hp, a 208 kg kerb weight, and a starting price of €10,999. It built its success on a simple idea — not much, but the right things — and an extremely active user community.

This is where the future BMW would fit, with the caveat that all BMW data is based on estimates or rumors; none of it is official.

Where BMW could have an advantage

If the target weight below 200 kg were met, the BMW would be lighter than the Ténéré, and in this category ten kilos really make a difference: during stationary maneuvers, when lifting it after a fall, and when riding standing up on loose terrain. The second foreseeable advantage is the electronics package: BMW is accustomed to offering TFT displays, riding modes, cornering ABS, and cruise control even on entry-level models, while the Ténéré remains deliberately spartan. The third is the dealer network: BMW assistance, spare parts, and financing are a tangible consideration for travelers.

Where the Ténéré remains ahead

The Ténéré 700 exists, can be bought today, and has seven years of development, spare parts, and aftermarket support behind it. The CP2 engine has a reputation for field-proven robustness, and the availability of accessories dedicated to the Ténéré 700 is among the broadest in the segment — a factor that serious travelers consider before the specification sheet. And it has 100 cc more: on the highway, with luggage and a passenger, you can feel the difference.

Not just the Ténéré: the middleweight class is crowded

If the final displacement really settled at around 600 cc, BMW would find itself in a particular position: below almost all of its stated rivals.

  • Honda XL750 Transalp — 755 cc, 92 hp, 210 kg, 21- and 18-inch wheels, list price around €11,000. It is the most road-oriented of the group in terms of tuning, but also the most complete in terms of features-to-price ratio.
  • Suzuki V-Strom 800DE — 776 cc, approximately 84 hp, 21- and 17-inch wheels, the heaviest in the comparison. Less sharp off-road, but very solid for touring.
  • Aprilia Tuareg 660 — 659 cc, 80 hp, the lightest and most effective through corners, with tubeless spoke wheels. Historically also the most expensive.
  • CFMOTO 800MT-X — 799 cc, approximately 95 hp, KTM-derived engine, aggressive price. It is the variable redefining price expectations in the segment.
  • KTM 790 and 890 Adventure — sportier and more extreme off-road setup, with a significant price gap between the two.
  • Norton Atlas — 585 cc, 70 hp, 19" front wheel, European entry price of around €9,250. It is the real benchmark: it shows what can be done today with that displacement and at what price.

The picture is twofold. On the one hand, a 600 BMW would risk being the least powerful in its class. On the other, precisely for that reason, it could attack from below: lower industrial costs, lower weight, lower price. It would not compete with the Transalp on performance, but it would take customers away through accessibility—and it would be the only one in that category to carry the propeller badge on the tank.

Who would buy this BMW

The profile that emerges is not that of the maxi enduro customer. It is a fairly specific audience:

  • people who graduate from the A2 license with an F 450 GS and want to stay within the family by moving up in size without going all the way to the 900;
  • people who look at the F 900 GS and find it too tall, too heavy, or too expensive;
  • people who use their motorcycle every day and look for unpaved roads on weekends, not extreme enduro;
  • people who have a maxi enduro in the garage and want something lighter as a second bike for leisurely trips;
  • people who would buy a Ténéré 700 today but want more electronics and a more extensive service network.

There is also a less-discussed segment of the market: people who take up Adventure riding after the age of forty, with an average budget and no desire to manage an imposing motorcycle. This audience is growing, and BMW currently serves it poorly because it has nothing to offer between 178 and 219 kg.

Why a 600 GS would be strategic

The mid-displacement Adventure segment has grown for a simple reason: maxi enduro bikes have become highly capable motorcycles, but also very large and expensive to buy and maintain. People who actually travel—not those who merely imagine traveling—have realized that a 200-kilogram motorcycle is more useful than a 250-kilogram one when the road ends, when it has to be loaded onto a ferry, or when it falls in the sand.

BMW also has industrial reasons. The twin-cylinder platform developed in Munich and produced in India has competitive production costs and already demonstrated room for increased displacement. Each additional model built on that foundation amortizes the initial investment, and that is exactly the reasoning Flasch publicly outlined when discussing a family of models around the F 450. A mid-size GS would most likely be only the first of those models: the same reports speculate about a derived naked bike, but that too remains hypothetical.

It is worth remembering that BMW has already been present in this segment. The history of the GS family includes models such as the F 650 GS, which for a generation of European riders was the gateway to motorcycle touring. A return to that space would not be entirely unprecedented: it would be a comeback.

When could it arrive

The most frequently cited indication is 2028, with production tentatively expected to begin in the second half of the year. To be clear: BMW has not announced any date, and a motorcycle spotted today undergoing testing with provisional bodywork still has a long road ahead, including homologation, industrialization, and fine-tuning. Plans may be delayed, changed, or reorganized.

If the schedule is maintained, the official presentation would plausibly take place at EICMA 2027, with the bike reaching dealerships during 2028. Some even speculate about an early reveal at EICMA 2026, but at present there is no evidence to support that.

What will it be called

The two names currently circulating are F 600 GS and F 650 GS. The former is consistent with the current nomenclature, which uses rounded displacement figures; the latter would revive a designation with considerable sentimental value in Europe. There is also the more romantic than realistic possibility of a reference to the old Dakar designation.

None of the three is confirmed. It is worth remembering that the actual displacement of the F 450 GS is 420 cm³, yet the model is still designated 450: BMW rounds up for commercial positioning, not metric precision. So even a 585 or 590 cm³ engine could quite reasonably be called a 600—or 650, if the marketing department decided that nostalgia mattered more than consistency.

The picture, in brief

There is a prototype. There is an obvious gap in BMW’s range. There is a technical platform that can be increased in displacement, and this has already been demonstrated industrially. There are official statements confirming the intention to build a family around that foundation.

As of today, there is no BMW F 600 GS. There is, however, a very strong likelihood that there will be one. For anyone choosing a mid-size adventure bike now, this news changes nothing concrete: the Ténéré 700, Transalp, and Tuareg 660 remain what they are. For those who can wait two years, EICMA 2027 is worth keeping an eye on.

Frequently asked questions

Has BMW confirmed the new mid-size GS?

No. BMW Motorrad has not issued any official statement about a GS positioned between the F 450 GS and F 900 GS. Only CEO Markus Flasch’s general statements about the intention to develop a family of models around the new twin-cylinder architecture have been confirmed.

When will the new mid-size BMW GS arrive?

The recurring estimate is 2028, but this is not an official date. BMW has not announced any timeline, and development programs can change.

How much horsepower will it have?

Rumors suggest 65–70 hp. There is no official data. For reference, the F 450 GS produces 48 hp and the F 900 GS 105 hp.

What engine will it use?

Most likely, a parallel twin derived from the F 450 GS architecture, enlarged to around 585–600 cc. It has not been confirmed whether it will share components with the Norton Atlas’s 585, which comes from the same TVS industrial group but uses a different crankshaft firing interval (270° versus BMW’s 135°).

Will it rival the Yamaha Ténéré 700?

Given its setup—a 21-inch front wheel, an off-road focus, and mid-size displacement—the comparison is inevitable. On paper, however, the BMW would be less powerful and potentially lighter, so it would not be a direct rival but rather a complementary model.

What wheels will it have?

The 21-inch front wheel is visible in the prototype images. Sources disagree about the rear: some indicate 18 inches, others 17. BMW has communicated nothing.

How much could it cost?

There is no official indication. Considering its positioning between the F 450 GS at €7,590 and the F 900 GS at €14,600, as well as the prices of its direct rivals, it is expected to be priced at around €10,000. This remains an unverifiable estimate.

How will it be positioned relative to the F 450 GS?

Above all, and decisively so: more displacement, more power, a twin front disc, a 21-inch front wheel instead of 19 inches, and a setup more geared toward off-road riding and travel. The F 450 GS would remain the entry-level model for A2 license holders.

How will it be positioned relative to the F 900 GS?

Lower down, in terms of performance as well as weight and price. The F 900 GS would remain the choice for those seeking full performance and long-distance touring capability.

Will it be suitable for off-road riding?

The clues point in that direction: a 21-inch front wheel, generous suspension travel, and low weight are the right conditions. But until definitive data on actual weight, geometry, and tuning are available, any assessment remains premature.

What will it be called?

It is not known. The most widespread journalistic speculation is F 600 GS and F 650 GS. BMW has neither registered nor publicly announced any name.

Will there be dedicated accessories?

Not yet. Until the motorcycle exists in production form, there are no compatible accessories: any compatibility claims currently circulating would be unfounded.
