No. 5
2015 MV Agusta F4 RR: Sexy, aggressive, even scary, the F4 RR represents a major technological shift with the addition of ride-by-wire throttle, 4-mode ECU, traction control, and electronically adjustable Öhlins suspension. It became the first production superbike to surpass 200 hp -- one that isn't easily tamed considering its punishing engine.

At full throttle, you can't catch a break until you reach redline. This bike will catapult you out of corners and devour straight lines in the blink of an eye.
