Riding in style and rejecting norms: The BMW R 18 Roctane presents itself exactly as it is. It is our modern take on a custom factory hot rod. Those who ride it don’t care about conventions. Fittingly, there is exclusive, high-class equipment hidden behind the rebellious aesthetic. Maximum comfort, technical highlights, and outstanding ergonomics – everything you would expect from a modern cruiser. Its rebellious heart is the iconic Big Boxer engine, which can pack a unique punch whenever you want to accelerate the fun.


Color: Black. Presence: Bold.

The attractive dark chrome finish gives the R 18 Roctane a characteristically dynamic look. The black highlights will meet even the highest standards for individuality and modernity. Components in dark chrome – from the exhaust system, to the pushrod tubes, right up to the trim panel components – emphasize the bike’s confident style.

Highlights for high expectations

The iconic front with a round LED headlight and 21-inch cast aluminum wheel paves the way. The mini ape-hanger handlebars, the standard footboards and the Dragster seat offer comfort on long tours. The elongated bagger silhouette ends with the stylish rear with a hard-shell case. The throaty boxer sound from the dark chrome rear silencer is impossible to miss.

Big boxer, big emotions

A bike that makes a statement – a drive system without compromises. It goes without saying that we installed our most powerful boxer engine. With a consistently high torque, it ensures an enjoyable ride over long distances. There is 110 lb-ft of torque available between 2,000 and 4,000 rpm. At 4,750 rpm, our big boxer delivers a whopping 91 hp.
