The BMW Middleweight GS Range Has Grown Up


Now BMW’s GS Adventure Line-Up gets serious with two new middleweights that have not only grown in displacement but also in handling and electronics. In 2018 we will see a brand new BMW F 850GS and F 750GS in the range.

The 2018 F 850GS makes 68 ft/lbs of torque at 6250, and the F 750GS 61 ft/lbs of torque at 6000 rpm.

The engines now feature two counterbalance shafts to help absorb vibrations, a crankshaft journal that is offset 90 degrees, and a firing interval of 270/450 degrees for smoother power delivery. The former 798cc engine, which was developed with Rotax, has a 360-degree firing order.

The six-gear transmission continues to delivers power to the rear wheel with a chain, but the drive system is now positioned on the left-hand side. Plus the 2018 F 850GS and F 750GS are equipped with a slipper-and-assist clutch.

Besides a redesigned and more powerful engine, the F series GS motorcycles have a stronger monocoque steel frames that use the engine as a stress member to save weight and improve chassis feel. BMW says the monocoque setup offers benefits in terms of torsional rigidity and robustness.

Both the F 850GS and F 750GS both come standard with Road and Rain riding modes as standard, along with ABS and ASC (traction control). For those who demand more adjustability, Pro riding modes with ABS Pro (shut off rear wheel ABS), DTC (traction control while leaning), and the new riding modes – Dynamic and Enduro. Enduro Pro is also available on the 850GS as an option.
