2019 BMW F 750 GS FIRST IMPRESSION P74 A NEW HEART The liquid-cooled, DOHC, eight-valve, four- stroke engine powering the F 750 GS is a ground up redesign, with BMW claiming 77 horsepower at 7500 rpm and 61 lb-ft of torque at 6000 rpm, via the 853cc engine that's both longer and wider at 84 x 77mm bore and stroke compared to the 92 x 75.6mm dimension of the 700. BMW engineers were charged with not only im- proving horsepower and reducing fuel consump- tion, but also reducing the vibrations felt by the rider at speed. To this end, they've fitted a second counterbalancer and changed the crankpin offset from 0° to 90° to give a 270°/450° firing inter- val and with it, an all-new, deeper exhaust note compared to the 0°/360° firing intervals of the old 798cc F 700 GS. That F 700 was fitted with a single connecting rod between the two main rods to dampen out vi- brations, but the 850 gets two dedicated counter- balancers mounted on the crankshaft and driven by spur gears. The result is one of the smoothest twin-cylinder motors I've ever ridden, one who's throttle response can be manipulated up to four different ways by the two standard ride modes of Rain and Road, and two optional extra modes of Dynamic and Enduro (the F 850 GS also gets an another mode of Enduro Pro). Getting that go to the chain drive that's been moved from right to left is a redesigned, six-speed gearbox that can be fitted with BMW's Gear Shift Assist Pro for clutchless up and down shifts as a factory accessory. The clutch is new, BMW fitting an anti-hopping (slipper) design so you can bang down the gears and not lock the back wheel up— the design also helps to give a lighter pull at the lever than previously. With the chain drive moved to the left, the exhaust has been relocated to the right, and the gas tank, which was normally found at the rear of the bike under the seat has been moved back to the traditional place of behind the steering head. This is one of the more easily spotted improve- ments made to the chassis design, as the top of the tank is now taller than the outgoing 700, and The new dash is superb and offers an absolute plethora of options for the rider. Mission control for all the electronic gizmos on the 750. It's been this way for years with BMW motorcycles. The brakes are pretty small, as are the fork legs. That alloy rim doesn't like hitting things hard at speed, either, and can dent easily.
