100 Years of Harley-Davidson! Hundreds of thousands at Sturgis! Jay Leno Rides. Peter Fonda Rides. Millions take to the road, to the track and to the air with one thing in common. They turn it over, rev it up, and on two wheels - they ride, they race, they jump, they fly, defying gravity on an incredible machine sometimes called a bike, a hog, or more simply, a motorcycle.
