BMW-R1200GS-1

You wouldn’t expect BMW to change the R1200GS very much. After all, the big dual-purpose boxer makes up more than half the firm’s motorcycle production, and almost 200,000 of the things have been sold since its arrival in 2004.When a bike is that popular, you’d be crazy to mess with it.

With new rivals, including Ducati’s Multistrada, on the way it’s made a significant change by updating the GS with a DOHC, radial eight-valve motor. The new lump is developed fromtheHP2 Sport unit, keeps the traditional GS capacity of 1170cc, and is shared with the revamped R1200RT as well as the Adventure.

So what exactly is new?
Main change is that DOHC motor, which is unusual because each cam opens one inlet and one exhaust valve, rather than both inlets or exhausts. Its max of 110bhp at 7750rpmmeans the GS gets a 5bhp boost at the top end. There’s also up to 10bhp extra power throughout the range, except for a dip at about 5500rpm where the old motor is slightly stronger.
