This Harley-Davidson XR750 “cut-away” bike illustrates the most dominant production racer ever built. It has reigned over America’s dirt track ovals for an amazing 40 years.
The factory produced small batches of the complete machine in 1972, 1975, 1978 and 1980. Since then, only the engine has been available, with the customer choosing an aftermarket frame from manufacturers such as Knight and C&J.The venerable XR750 has met and defeated many foes over its 40+ years in competition. It is today facing renewed challenges from talented teams fielding machines from Kawasaki, Ducati and Triumph. The reason for Harley-Davidson’s domination is often speculated. In short, it is a purely American design for the purely American sport of half-mile and mile dirt track racing. Its tractor-type power from the 45 degree twin is the perfect tool for that purpose. Times may have changed around the XR750, but it is still out there accomplishing its intended goal; AMA Pro dirt track domination.
