A pure racing special, the RR1000R was Erik Buell's answer to a request for a competitive chassis around the Harley-Davidson XR engine after AMA rules lifted the displacement cap to 1000 cc. It used a compact chassis, 16-inch magnesium wheels and a high, forward-set engine, and only a handful were made.
