At the heart of the new adventurers are the two new parallel-twin engines, both with a displacement of 853cc, but different output.
The F 850 GS has 70kW (95hp) of power at 8250rpm and 92Nm of torque at 6250rpm while the F 750 GS has 57kW (77hp) at 7500rpm and 83Nm at 6000rpm.
BMW says the F 750 GS is “designed for all riders” with a low seat height and “all-round qualities”. It features mag wheels with a 19-inch front.
However, the F 850 GS not only has more power and torque, but BMW says it has more touring and off-road features. They include wire wheels and a 21-inch front.
New F 850 GS and F 750 GS engine
BMW says the engine has a 90-degree crankshaft and a 270/450-degree firing interval with two counterbalance shafts to smooth it out.
A self-amplifying, anti-hopping clutch provides a lighter lever feel and the drop in engine drag torque prevents wheel lock-ups on downshifts.
The six-speed gearbox with secondary drive is now positioned on the left.
Rider aids include ‘Rain’ and ‘Road’ riding modes, ABS and automatic stability control ensures a high level of safety.
The F 750 GS and F 850 GS can be fitted ex-works optional equipment such as Pro riding modes, dynamic traction control and banking-capable ABS Pro.
The bridge frame of the new F models is made of deep-drawn, welded components and integrates the engine as a co-supporting element.
BMW claims this improves torsional rigidity and “robustness”.
The fuel tank is back in the traditional position for improved centre of gravity.
The F 850 GS adds a Rallye style variant with emphasis on off-road capabilities.
There is also a range of optional equipment including different seat heights, windshields, full LED headlight, Connectivity equipment with TFT display, Keyless Ride, Gear shift assistant Pro, Dynamic ESA and eCall.
