The Harley-Davidson XR-750 became famous for dominating American flat-track competition.
Harley-Davidson introduced the XR-750 in 1970 for American dirt-track racing. The motorcycle was developed for the demanding conditions of the AMA Grand National Championship, where acceleration, traction, durability, and controllable handling were crucial. Its racing success made the XR-750 one of the most important competition motorcycles in American motorcycle history.
The XR-750 was also closely associated with stunt performer Evel Knievel, who used versions of the motorcycle in many of his jumps. That public exposure helped make the model recognizable beyond racing circles.
The XR-750 was a purpose-built racing motorcycle, not a normal street model. It should not be confused with the later XR-1000 street motorcycle, which used the XR name but served a different role.
