Harley-Davidson XR750
The Harley-Davidson XR750 was primarily manufactured for racing on the regular road and the dirt road. The likes of Mark Brelsford, Evel Knievel, Jay Springsteen, and Cal Rayborn have all driven this motorbike. After all, it is a truly impressive thing. It was actually so popular that it was eventually deemed a rarity, which is why collectors love it. An XR750 unit was displayed at exhibits called the American on the Move and the Art of the Motorcycle.

Ducati Supersport
During the Imola 200 race, the Ducati Supersport bagged both the 1st and 2nd place. Bruno Spaggiari and Paul Smart used it in the race! It was made from 1972 to 1981. It is fair to say that it paved the way for newer models. The bike came with a new body style, better handling, and a twin-cylinder engine.
