193 HP In Your Face

Let’s just get one thing straight, BMW’s S1000RR is most definitely not a beginner’s bike. This beast makes 193 HP (at the crankshaft) from just one liter of displacement – amazing. In any case BMW put up this really cool video of the valves in action. After a certain RPM it’s impossible to see what’s happening with the valves (slo-mo would’ve been nice), but still, it’s incredible to think this is also happening inside your bike’s engine. Maybe not this furiously, but you get the idea. In case you’re wondering, some MotoGP bikes use pneumatic valves (instead of springs) to deal with the even crazier RPMs involved at the world’s top level of motorcycle racing.
