The 1938 Harley-Davidson UL motorcycle featured a Flathead V-twin instead of the newer Knucklehead. It was a Sport Solo model with new colors and striping available. See pictures and learn about the Harley UL.
The 1975 Harley-Davidson XL-1000 and XR-750 were often altered so few remain their original state. The engine for the XR-750 racer was based on the Sportster but it had dual carbs and high-mounted exhaust. Check out these rare powerful Harleys.
