A new video has emerged with shots of the new BMW 1250GS, along with details of a new variable valve timing system called SHIFTCAM that at low revs has less valve lift for smooth efficient power and as revs increase shifts the cams sideways exposing the valves to the different cam profile with higher valve lift and possibly different opening and closing timing better suited for producing more power at higher revs.
