in 2013, BMW motorrad unveiled the concept ninety, a collaboration with american expert custom bike builder and road racer roland sands, that envisioned a re-interpretation of the 1973 R 90 S. during the occasion of concorso d’eleganza villa d’este 2014 at lake como, the german luxury brand previewed the future of boxer-powered engines once again, in the form of the ‘BMW concept roadster’.

typical of a bimmer roadster, the one-off bike features a tuned two-cylinder 1,170cc boxer engine, single-sided swing arm with cardan drive and a light tubular space frame. in its latest generation, it generates 123 horsepower at 7,750 rpm with a maximum 92 lb-ft of torque.

split coloring makes for a visual separation of the dark engine area below and the light seating area above with the fuel tank and rear section. the dark bottom section moves concept roadster visually closer to the road surface, meanwhile the lighter upper section conveys lightness and a low center of gravity.

fork tubes, rear shock absorbers and brakes are elegantly set apart by their anodized color-scheme
