On this episode of On Two Wheels, it's Part Two of Motorcyclist magazine's Class of 2012 shootout. This time around the staff is testing the best Europe has to offer, with the 2-time and defending champion Aprilia RSV4 taking on the BMW S1000RR, MV Agusta F4R, and Ducati's highly anticipated 1199 Panigale S. The bikes face the same wringer as their Japanese counterparts in Part One, with testing on the street, dragstrip, and of course the racetrack. Will Europe's ultra-elite live up to the hype?
