Motorcycle: 2009 Aprilia RS 125
Rider: Megan Fox
Complex Says: Ace mechanic Mikaela Banes (Fox) rescues her hapless boyfriend, Sam Witwicky (Shia LaBeouf) on her trusty RS 125. Don't let its small size fool you. This lightweight pocket rocket is powered by the famed Rotax-Aprilia two-stroke engine. There's a reason this bike owns the 125cc classes in Europe.
