Interesting to see the valve rotators on top of the valve springs - rotating the springs (past 1:34 one can see the red markings on the valve spring making a full rotation)It starts off slow, but around 1:30 it gets crazy and you can't even see the springs move.
^ Maybe because BMW only recently (last couple of years, with this new RR, the Dakar bikes, etc) decided to make bikes that are not meant for old farts only....
