BMW unveiled two new middleweight F-series adventure bikes at the EICMA Show in Milan this week, with the new-for-2018 F 750 GS and F 850 GS slated to replace the current 700 and 800 GS models.
As well as the new engine, there’s a new chassis, updated suspension, additional electronics and a conventional fuel tank now replaces the underseat unit of the outgoing machines.
Both versions are powered by the same displacement 853cc parallel-twin engine with a 270-degree firing interval, though the 750 is tuned for 77hp at 7500rpm and 83Nm at 6000rpm, while the more extreme 850 variant gets 95hp at 8250rpm and 92Nm at 6250rpm.
Matched to a six-speed gearbox and a new anti-hopping clutch, it’s mounted in a monocoque style tubular-steel bridge frame with the chain final drive now on the left-hand side of the bike. Similarly, the exhaust is now located on the right-hand side of the bike instead of the left as on the duo’s predecessors.
The 750 is suspended on conventional 41mm forks, it rolls on a 19-inch front wheel and 17-inch rear and boasts a standard seat height of 815mm. The 850 gets 43mm upside-down affairs and a 21-inch front wheel. For the first time, the larger of the two bikes benefits from tubeless tyres thanks to the offset spokes on the wore wheels and its standard seat height is 20mm lower than its predecessor at 860mm.
Electronics wise, it’s two engine modes (rain and road) as well as ABS and stability control as standard fitment, but BMW offers pro riding modes, cornering ABS, dynamic traction control, gear shift assist and a swag of other extras as optional extras on both machines.
