The Harley-Davidson XR-750 is a racing motorcycle made by Harley-Davidson since 1970 primarily for dirt track racing but also for road racing in the XRTT variant. The XR-750 was designed in response to a 1969 change in AMA Grand National Championship rules that leveled the playing field for makes other than Harley-Davidson allowing Japanese and British motorcycles to outperform the previously dominant Harley-Davidson KR race bike.
