S1000RR valves at 14,000 RPM

[Relax]

I couldn't stop smiling while watching this! I think the only way this could have been any better was to overlay the tach.

"This video shows an operational cutaway of a BMW S1000RR — a 193HP superbike — bumping against its 14,200RPM redline. A cam and valvetrain at 118 cycles per second is an amazing sight (and sound)"

230 odd years of development makes for some amazing possibilities with ICE motors. It's astonishing to me that motors can do this over and over and over without exploding.

As for making it better, if ever there was a video crying out for a super slow-mo camera, a la Mythbusters...

The springs rotated faster than I expected.

Holy fook.

Makes me want to granny shift all my vehicles from now on...

Not the best viewpoint, but here's one of a desmodromic valve in action:

Amazing to be able to see these in action. I’m the first one is that vapourized oil or smoke?
