BMW Motorrad have long been a leader in the large-displacement adventure segment with its R1200GS. But the Bavarian brand has also been a popular upper middleweight adventure class manufacturer thanks to its F series machines, the F700GS and F800GS. For 2018 BMW is looking to enhance it’s position as a major player in the sector with two new updated models, the F750GS and the F850GS.
One Engine, Two Bikes
As with the 700GS and 800GS, the new F750GS and F850GS will share the same, liquid-cooled Parallel Twin engine. This time around it’s an 853cc mill (up from 798cc) that on the 750 pumps out 77 horsepower at 7500rpm and 61 lb-ft torque at 6000 rpm. The 850 produces 95 horsepower at 8250 rpm and 68 lb-ft torque at 6250 rpm.
The crankshaft is revised with a 90-degree journal offset and 270/450 degree firing interval, and there are two opposed counterbalance shafts to help reduce engine vibration. At the top are two tooth-belt driven camshafts that operate the four valves per cylinder.
BMW updated the six-speed gearbox design and includes a mechanically controlled, wet multi-plate clutch with slipper functionality on both models.
Engine output can be modified through two ride modes, Rain and Road. Rain provides softer throttle response and dials the automatic stability control, dynamic traction control and ABS to deal with wet conditions.
Road mode allows full throttle response and configures ASC and ABS for pavement duty. Riders can also choose to add in optional Pro modes, Dynamic and Enduro. If the 850GS is your steed, then an Enduro Pro mode is available as an upgrade also.
Chassis and Suspension
A newly developed bridge frame uses the engine as a stressed member. The fuel tank was required to be repositioned, in the traditional location between the seat and the steering head rather than underneath the seat on previous models.
The 750GS sits atop a 41mm telescopic fork with 5.9 inches travel and a rear shock with preload adjustment and 6.9-inches travel. It rolls on a 19-inch front wheel and 17-inch rear, made from die-cast aluminum.
The 850GS has a 43mm USD fork with 8 inches travel and the same rear suspension set-up as the 750. More off-road oriented 21-inch front and 17-inch rear spoke wheels are fit on the 850.
BMW’s Dynamic ESA electronic suspension adjustment is available as optional equipment for both models.
Braking is handled by dual 305mm discs on the front with dual-piston calipers. At the rear is a 265mm disc and single-piston floating caliper. BMW Motorrad ABS comes standard, and ABS Pro is available, as is a dynamic brake light, as an upgrade.
All in all, the F750GS weighs 493.8 pounds and the F850GS tips scales at 504.8 pounds ready to ride.
Ergonomics and Styling
Seat height remains the same as before with the 750GS, at 32-inches. The 850GS is slightly lower than its predecessor at 33.8-inches (down from 34.6 on the 800). Lower seats are available for both motorcycles as optional equipment.
Each model receives the asymmetrical GS-style headlight and beak to bring it closer in looks to the larger GS adventure bikes offered by BMW.
There’s a new instrument cluster design with an analogue speedometer and multifunction display on both bikes.
The F750GS will be available in Light White, Austin Yellow Metallic and Stereo Metallic Matte colorways. The F850GS has Racing Red, Pollux Metallic Matte or Rallye-inspired colorways to choose from.
As always, BMW offers a broad range of electronics upgrades and riding packages for each machine.
We’ll update as pricing and availability details are released.
