Sin City star Rosario Dawson is furiously studying to get a motorcycle licence, after recently purchasing a Harley-Davidson bike. The actress is even perfecting her motorcycle skills on a dirt bike, because she doesn't want to take a chance on ruining her new ride. She explains, "I got a Harley! I got a Sportster- an '83. "Actually, I don't have a licence yet. My boyfriend (actor Jason Lewis) for Christmas got me a dirt bike, so I've been taking that around. "I've been practicing on the dirt bike because I don't want to fall over with my beautiful Harley and get it all scratched up before I learn to work the clutch and all that. "It's really pretty. I go out to the garage and look at it. I got so excited when I got my little license plate! It's really cute!"
