You may remember the cult motorcycle YouTube classic “BMW S1000RR Titanium Valves at 14,200 RPM“, well now we have a sequel to that movie. Showing the BMW’s titanium valves from a cylinder’s point of view, this S1000RR is rev’d through the rpm range with interesting results.
Because of the shutter effect on the video recorder we see the valves go through their motions until finally seemingly stopping as the shutter rate and valve moment go out of sync and re-sync. If you ever wanted to know what was going on inside you bike, here’s a good start on the subject. Video after the jump.
