BMW R1200 GS Adventure, 2014-2019

New model launched for 2013
The Adventure edition the year later

Upgraded in almost every department, bringing forth an almost new two-wheeler, which may be considered one of the best adventure machines on the market.

At its heart lies an air-cooled, four-stroke, 1170cc, boxer twin cyclinder mated to a six-speed manual transmission, and now produces 125 horsepower and 125 Nm of torque, 15 horsepower and 5 Nm of torque more than its previous embodiments.

And the good news doesn't stop here. It now comes standard with E-gas (ride-by-wire), which leads to five selectable riding modes, Rain, Road, Dynamic, Enduro and Enduro Pro.
In addition, BMW Motorrad Integral ABS comes as standard, as well as an adjustable windshield and a 8 mm higher ground clearance.

For the 2014 through 2016 model years, incremental annual updates were made, including adjustments to road handling, and adding options such as LED headlights, keyless ignition, a quickshifter, an antitheft system, and another lower seat option. A new ABS mode available as a software update allows safer braking while cornering.

2017: The bike was given a facelift, with technical changes to meet European EU4 regulations.
Side reflectors and an on-board diagnostic indicator light in the cockpit to indicate a malfunction were added.
Like the R1200GS Adventure, all liquid-cooled boxer models were given a damper on the transmission output shaft. The selector drum actuator, transmission shafts, and transmission shaft bearing were revised.
The GS was also given a new crash bar option, allowing cylinder protection covers to be mounted, as had been standard on the Adventure.

The model exits the BMW model range in 2019
