In the F 750 GS there are tamer 77 HP (57 kW) at 7,500 rpm and 83 Nm maximum torque at 6,000 rpm.
Bore / stroke: 84 x 77 mm.
Instead of the previous balancing rod, a balancing shaft driven by a spur gear, rotating in front of and behind the crankshaft, ensures smooth running.
The new in-line twin cylinder from the BMW F 850 GS and BMW F 750 GS.
It was designed from scratch.
In the BMW F 850 GS, it develops 95 hp (70 kW) at 8,250 rpm and provides a maximum torque of 92 Nm at 6,250 rpm.

Series sounds like Vau
The in-line twin cylinder of the F 850 GS and F 750 GS is a completely new design with interesting technology. The new engine will be built in China.
Who invented it? Bavaria. Because the 853 cm³ in-line two-cylinder (bore / stroke: 84 x 77 mm) was developed, which BMW expressly emphasizes, in Munich. But it is built, which you only find out when explicitly requested, at Loncin in China, which is where the single-cylinder G 650 models came from.
About the technology: BMW has said goodbye to the compensating conrod of the previous parallel twin of the F 800 GS, which was presented as a novelty in 2007. Instead, the new drive has from F 750 GS and F 850 GS two balance shafts, which are placed in front of and behind the crankshaft, are driven by a spur gear and are intended to minimize vibrations.
BMW F 850 R and F 850 GT are likely
The two connecting rods of the new BMW two-cylinder are positioned on the crankshaft with a crank pin offset of 90 degrees. At the same time, the ignition takes place at a distance of 270 or 450 degrees, which corresponds exactly to the ignition sequence of a 90-degree Vau twin-engine and, of course, should sound like that.
In the BMW F 850 GS, the more powerful of the two new F models, the new engine develops 95 hp (70 kW) at 8250 rpm. It reaches its maximum torque of 92 Newton meters at 6250 rpm. The F 750 GS and F 850 GS mark the start of a new BMW two-cylinder series with the new engine. Nothing is official yet, but BMW will certainly add more models powered by the new twin, such as the naked bike F 850 R or the touring version F 850 GT.
