2019 BMW R 1250 GS | More grunt and more tech
The new bike features an all-new variable valve setup, which uses sliding concentric shafts on the cam drive, with a shift system not unlike a gearbox, with a slotted shift drum that moves different cam profiles into and out of operation. It allows BMW to have lower valve lift and duration for low-rev performance, then switch to more aggressive cam profiles at high revs for improved power production.
The new ShiftCam system is only on the inlet shaft, but is good enough to raise peak power to 136bhp - nice.
