Sturgis

S4, E5: The Top Gear hosts embark on a two-wheel road trip to the world's largest automotive event, the annual Sturgis Bike Week. Starting out on scooters and passing challenges to progress to the bigger bikes they'll need to ride to fit in at the rally, the hosts go through hell as they close in on Sturgis. The winner will race a super-charged Ariel Atom against a 200 mph sports bike, while the loser will have to take part in a stunt, courtesy of History channel's newest series, American Daredevils.
