Since 1964, Playboy's given a car to every Playmate of the Year. This year, the magazine gave Hope Dworaczyk a BMW S1000RR motorcycle. This exclusive retrospective shows how her bike stacks up against the rest of the Playmate garage.

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). (H/T to Chris!)
