BMW pulled the covers off two new mid-sized GS models, with a new 2018 F850GS and F750GS replacing the F800GS and F700GS. The new models were completely redesigned, with the F750GS as a more entry-level GS model and the F800GS for more advanced ADV riders.
Like the outgoing models, the F850GS and F750GS share the same engine, now an 853cc parallel Twin. On the F850GS, the engine claims a peak output of 95 hp at 8250 rpm and 67.8 lb-ft at 6250 rpm, while the F750GS’ engine is tuned down to a tamer 77 hp at 7500 rpm and 61.2 lb-ft at 6000 rpm. The engine uses a 90-degree journal offset crankshaft for a 270/450 firing interval while twin counterbalance shafts help offset vibrations.
The engines are mated to an anti-hopping clutch and six-speed transmissions, with the drive chain now switching over to the left side and the exhaust positioned on the right. A gear shift assist pro option enables clutchless shifting.
The F850GS and F750GS offer two engine modes, Rain and Road, with ABS and automatic stability control as standard. Additional Dynamic and Enduro ride modes (plus Enduro Pro for just the F850GS) and dynamic traction control and banking-capable ABS can be fitted as an ex-works option.
The F models receive a new steel bridge frame replacing the outgoing models’ tubular steel space frame. The new frame incorporates the engine as a supporting element and allows BMW to relocate the 4-gallon fuel tank from under the seat to a more conventional location in front of the rider.
The F750GS is equipped with a 41mm telescopic fork offering 5.9 inches of travel and a preload-adjustable rear shock with 7.0 inches of travel. The more off-road capable F850GS uses a beefier 43mm fork with 8.0 inches of travel and fender-mounted covers to protect the suspension from debris, and a preload and rebound damping adjustable rear shock with 8.6 inches of travel. BMW’s Electronic Suspension Adjustment system is available as an ex-works factory option.
The F850GS comes fitted with wire spoke aluminum wheels, a 2.15×21 wheel up front and a 4.25×17 wheel at the rear. The F750GS’ wheels are cast aluminum, with a 2.5×19 wheel up front and 4.25×17 wheel at the back. Tubeless enduro-style tires come standard for both models, with a more lugged tire offered as an option for the F850GS.
Both models use dual 305mm front brake rotors with two-piston floating calipers up front and a single 265mm rear disc with single-piston caliper at the rear.
The F750GS’ seat is 32.1 inches from the ground, just like the F700GS, while the F850GS’ loftier 33.9 inch seat height is 0.8 inches lower than on the F800GS.
Other details include full LED headlights, 6.5-inch TFT displays, BMW’s multi-controller, and sharper bodywork. The F750GS has a claimed curb weight of 493.8 pounds while the F850GS claims a curb weight of 504.9 pounds.
The 2018 BMW F750GS will be offered in Light White, Austin Yellow Metallic and an upgraded Exclusive model in Stereo Metallic Matte that comes with hand guards and an anodized silver handlebar. The 2018 BMW F850GS will be available in Racing Red, as well as in an Exclusive version in Pollux Metallic Matte and a Rallye edition Light White, both with hand guards, galvanized radiator cover and gold-colored fork tubes.
