We have known about the 2019 BMW R1250GS for some time now. Details about the bike’s new boxer engine were published over a month ago, which tipped off the use of variable valve timing on the venerable GS. We also learned that a displacement increase of1,254cc was coming, and with that a modest power increase of 134hp and 92 lbs•ft of torque.
Then last week, we got a teaser of the 2019 BMW R1250GS adventure-tourer, as a promotional video was leaked onto the internet, and it showed us in great detail what to expect from BMW Motorrad. More specifically, the video showed us the German motorcycle manufacturer’s new variable valve timing technology, called ShiftCam.
Providing two possible cam lobes for each valve, the camshaft shifts position in the cylinder head to engage one of the two lobes, depending on throttle inputs. Hence the name, ShiftCam.
This allows for different intake valve actuation (timing and stroke) during touring and city riding, for better gas mileage and softer throttle response, but still leaves the engine the ability to wake up during spirited riding, and provide more power.
The new “ShiftCam” boxer engine is coming to all the “R” bikes in BMW’s lineup for 2019, which of course includes the 2019 BMW R1250GS.
