BMW's 2027 GS lineup covers four distinct approaches to adventure riding. The new F 450 GS introduces a lightweight 420cc parallel-twin platform, while the R 12 G/S combines classic boxer-engine character with off-road-focused dimensions. At the larger end, the R 1300 GS and R 1300 GS Adventure share a 1,300cc boxer engine but offer different approaches to touring and long-distance exploration.
Understanding their differences is about more than engine size. Weight, fuel capacity, wheel configuration, suspension travel and standard equipment all influence which motorcycle makes the most sense for different riding needs.
2027 BMW GS Models at a Glance
| Specification | F 450 GS | R 12 G/S | R 1300 GS | R 1300 GS Adventure |
|---|---|---|---|---|
| Engine | 420cc twin | 1,170cc boxer | 1,300cc boxer | 1,300cc boxer |
| Power | 48 hp | 109 hp | 145 hp | 145 hp |
| Torque | 43 Nm | 115 Nm | 149 Nm | 149 Nm |
| Road-ready weight | 178 kg | 229 kg | 237 kg | 269 kg |
| Fuel capacity | 14 L | 15.5 L | 19 L | 30 L |
| Front wheel | 19 in | 21 in | 19 in | 19 in |
Weights are BMW's published DIN unladen weights in road-ready condition. The figures in this comparison are drawn primarily from BMW Motorrad Global technical information; equipment and optional-package availability may vary by country.
The biggest distinction is the motorcycles' intended use. The F 450 GS is the lightest model in this comparison, the R 12 G/S has the most off-road-oriented front-wheel and suspension specifications, and the R 1300 GS models focus on larger-capacity adventure touring.
1. 2027 BMW F 450 GS: A New Lightweight Adventure Platform
The F 450 GS is the newest platform in the lineup. Its 420cc liquid-cooled parallel-twin engine produces 48 hp at 8,750 rpm and 43 Nm of torque at 6,750 rpm.
A 135-degree crankpin offset and balance shaft are part of the engine design. BMW's Easy Ride Clutch (ERC) is a further development of a centrifugal clutch that removes the need to operate the clutch lever manually while riding, including when starting and changing gears.
Other key specifications include:
- Road-ready weight: 178 kg
- Fuel capacity: 14 litres
- Seat height: 845 mm (33.3 inches)
- Front and rear suspension travel: 180 mm
- Front and rear wheel sizes: 19 and 17 inches
The F 450 GS is considerably lighter than the boxer-powered models in this comparison. Its smaller engine, lower published weight and compact dimensions make it a different proposition from the larger GS touring motorcycles.
For riders who want an adventure motorcycle without moving directly into the weight and engine capacity of the R 1300 GS family, the F 450 GS provides a separate option.
2. 2027 BMW R 12 G/S: Boxer Performance with Off-Road-Focused Dimensions
The R 12 G/S takes inspiration from BMW's historic R 80 G/S while using a modern 1,170cc air/oil-cooled boxer twin.
It produces 109 hp at 7,000 rpm and 115 Nm of torque at 6,500 rpm. Compared with the F 450 GS, it has a substantially larger engine and a different chassis configuration.
Its off-road-oriented specifications include:
- 21-inch front wheel and 17-inch rear wheel as standard (an 18-inch rear wheel is included with the Enduro Package Pro)
- 210 mm front suspension travel
- 200 mm rear suspension travel
- 240 mm ground clearance (255 mm with the Enduro Package Pro)
- 229 kg road-ready weight
- 15.5-litre fuel tank
The 21-inch front wheel and 240 mm ground clearance (255 mm with the Enduro Package Pro) distinguish the R 12 G/S from the R 1300 GS models, which use a 19-inch front wheel. Its suspension travel also reflects a different chassis setup.
For the 2027 model year, BMW's global update lists Frozen Brooklyn Grey Metallic for the R 12 G/S Option 719 and Option 719 II styles, replacing Sandrover Uni matt. The underlying 1,170cc boxer specification remains the basis of the model's published technical data.
The R 12 G/S stands apart through its 21-inch front wheel, long suspension travel, ground clearance and boxer engine—not through a claim that it is automatically better in every type of off-road riding.
3. BMW R 1300 GS vs R 1300 GS Adventure: What Is the Difference?
Both motorcycles use BMW's 1,300cc air/liquid-cooled boxer engine, producing 145 hp and 149 Nm of torque. Their key differences are fuel capacity, weight, dimensions and touring equipment.
| Specification | R 1300 GS | R 1300 GS Adventure |
|---|---|---|
| Engine | 1,300cc boxer | 1,300cc boxer |
| Power | 145 hp | 145 hp |
| Torque | 149 Nm | 149 Nm |
| Fuel capacity | 19 L | 30 L |
| Road-ready weight | 237 kg | 269 kg |
| Seat height | 850 mm (33.5 in) | 870 / 890 mm (34.3 / 35.0 in) |
| Front suspension travel | 190 mm | 210 mm |
| Rear suspension travel | 200 mm | 220 mm |
Fuel Capacity and Long-Distance Riding
The most obvious difference is the fuel tank. The R 1300 GS holds 19 litres, while the Adventure has a 30-litre tank.
That gives the Adventure 11 litres more fuel capacity, which can be useful when planning longer stretches between fuel stops. Actual riding range still depends on speed, terrain, load and riding conditions.
The Adventure also features a larger windscreen, hand protectors with integrated indicators, additional lighting and dedicated luggage and accessory mounting points. These features support its more expedition-oriented equipment package.
Weight, Height and Chassis Differences
The Adventure weighs 32 kg more than the standard R 1300 GS in BMW's published road-ready specifications.
It also has a higher seat-height range and greater suspension travel. These differences matter when considering low-speed manoeuvring, standing riding position, luggage loads and the type of terrain a rider regularly encounters.
The standard R 1300 GS offers a lower published weight and a smaller fuel tank. The Adventure adds fuel capacity and touring-oriented equipment, but riders should consider whether they actually need those additional features.
Neither model is automatically better. The decision depends on whether the rider values the standard GS's lower published weight and smaller tank, or the Adventure's larger fuel capacity and touring-focused equipment.
4. Which 2027 BMW GS Should You Choose?
The published specifications point to four different use cases:
- F 450 GS: A lower published weight, 420cc twin and more compact adventure platform.
- R 12 G/S: A boxer engine with a 21-inch front wheel, 240 mm of ground clearance and long suspension travel.
- R 1300 GS: The 145 hp, 1,300cc boxer platform without the Adventure model's 30-litre tank and higher published weight.
- R 1300 GS Adventure: A 30-litre tank, larger touring equipment package and long-distance carrying setup.
5. Can You Upgrade an Older BMW GS to Get Some of the Newer Models' Look and Function?
A new GS brings changes to its engine, chassis, suspension, fuel system and factory electronics. Accessories cannot turn an older motorcycle into a 2027 model or reproduce those underlying engineering changes. However, owners of the BMW R 1200 GS and R 1250 GS can refresh selected details and improve practical features such as cockpit appearance, navigation placement, rider contact points and luggage carrying.
The goal is not to copy a new motorcycle piece by piece. It is to make the GS you already own more comfortable, functional and suited to the way you ride. Here are a few examples of upgrades currently listed for specific earlier GS models.
