The BMW F 800 S/ST is for real fun-seekers. Thanks to the fast acceleration of its parallel twins and maximum
torque of 86 Nm at 5,800 rpm and 62.5 kW (85 bhp), this machine offers superb entertainment. And so that
its proud owners don’t have to spend valuable time getting dirty working on the engine, the F 800 S/ST is
equipped with a low-maintenance belt drive. Where curves are concerned, the general consensus is the more,
the merrier – at least where the chassis of the BMW F 800 S/ST is concerned. Telescopic forks at the front,
aluminium swinging arm at the rear, and away we go. The new F 800 boasts a sporty half fairing in the S
version and a full fairing suitable for touring in the ST version. This machine demonstrates that you can only
really have fun if the technology can be taken seriously.
