Primal - that's the R 1150 R Rockster. It's predatory by nature and a high-performance by design - an evolution in naked bike engineering. You'll swear the pavement quivers when you fire up the Rockster's new twin-spark engine. The latest innovation in BMW boxer design, the two spark raises the bar on reliability and performance.

And there's plenty of bite behind that bark. Wide open, the Rockster shoots across a tarmac at up to 122 mph, sprinting from 0 - 62mph in a mere 4.2 seconds.

But even perched on its center stand, the Rockster epitomizes speed. Every angle screams aggression and the high-contrast black and citrus or black and orange war paint gives the Rockster a unique presence.
