The new 1170cc, Boxer twin SOHC motor in the BMW R1200GS Adventure is taken from the best-selling motorcycle, the BMW R1200GS. It’s powerful, torquey and well-geared for effortless cruising at motorway speeds. The  BMW R1200GS Adventure's gearbox is pretty indifferent; clunky, with the odd false neutral, especially from second to first. Sixth is no longer the overdrive it was on the older BMW R1150GS Adventure, on this motorcycle the ratio is a normal accelerative gear.
