See the BMW S1000RR valves in action in this video and while you might think that nearly three and a half minutes of this is boring, it’s actually very mesmerising. It’s not every day we get to see the engine function of a bike with 193 hp. The S1000RR lightweight engine of just 59.8 kg is due to the use of superlight titanium, and it can rev to a maximum of 14,200 rpm, with maximum torque output of 112 Nm at 9,750 rpm.
