Produced from 1970 to 1985, this motorcycle went down in AMA history as the most successful racing motorcycle of all time.
Many Harley riders today are unaware of the brand's racing roots. Fortunately, the XR750 was the preferred choice for many riders who crossed the finish line first. According to the American Motorcyclist Association, this motorcycle is the winningest motorcycle in the organization's history. Many of the early models featured a 748cc air-cooled V-twin engine that produced 82 horsepower and reached a top speed of 115 mph (approximately 185 km/h). It's fair to say that this bike already exceeded expectations for a lightweight racer that would be used on both flat track and rough terrain. Produced from 1970 to 1985, this motorcycle went down in AMA history as the most successful racing motorcycle of all time. It was even the bike that Evel Knievel rode until his last jump in 1977.
