BMW R 1100S (2003 - 2004)

The BMW R 1100S, a sports tourer that defies convention with its potent boxer engine and sleek, modern design. This four-stroke, two-cylinder horizontally opposed motor, featuring 4 valves per cylinder, unleashes a thrilling riding experience that’s as much at home on the open road as it is on the track.

The motor itself is a marvel, with a telelever front suspension system that provides unparalleled stability and a paralever rear suspension that’s adjustable to suit any riding style. And then there’s the engine, with its free-revving nature and addictive throttle response, making it impossible to resist the urge to push the limits of speed and agility.

As I spent 1250 miles testing the R 1100S on UK roads, French, Belgian, and German motorways, and the infamous Nurburgring circuit, I can confidently say that this bike is an absolute joy to ride, with its comfortable ergonomics, precise handling, and exhilarating performance.
