as a fully stressed member of the frame. Capping the engineering firsts in this design was Buell's use of a horizontally mounted suspension located beneath the engine utilizing a shock that operated in reverse of the conventional compression-rebound design. Fifty RR1000 models were produced during 1987-1988 before the supply of XR1000 engines was depleted. Buell saw the newly-developed 1203 cc Harley-Davidson Evolution engine being used in their 'Sportster' model line as solid base platform to further tune the performance and handling qualities of his bikes. The RR1200 model was introduced during 1988 with a redesigned chassis to incorporate a modified version of this different engine design. Through 1989, 65 were produced for sale. In 1989, Buell introduced the RS1200 model, a two-seat version of the RR1200 marketed to riders who demanded both world-class performance and desired passenger capacity. 105 of these models were produced through 1990. In 1991, Buell incorporated a five-speed transmission mated to the 1203 cc engine. Buell responded to Harley's revised engine mounting points by further improving an already innovative design: the RS chassis. Stainless steel braided brake lines and a six-piston front brake caliper. Later that year, Buell introduced a single-seat version of the RS1200 model, dubbed the RSS1200. It won approval of the industry press for its lean, clean lines. Combined production of RSS and RS models totaled 325 through 1993. Buell American Motorcycles, subsidiary of Harley-Davidson In 1987, Devin Battley smuggled Erik Buell onto a cruise ship for the Harley-Davidson annual dealer's meeting. Battley told Harley-Davidson then-CEO, Vaughn Beals, that Buell could give the company a performance image with no risk to Harley. They set up a table for Buell to speak with dealers; by the end of the cruise he had deposits and orders for 25 motorcycles. Attendees such as Bill Bartels, Don Tilley, Devin Battley and Frank Ulicki later become some of Buells most successful dealers. In the 1990s, Buell reformed his house as the 'Buell Motorcycle Company' in which Harley-Davidson invested a 51% interest. Harley-Davidson bought complete control of Buell Motorcycle in 2003, and distributed all Buell motorcycles through select Harley-Davidson dealerships. Erik Buell remained responsible for the engineering and design of all Buell motorcycles. Buell led the company to create some of the most innovative, usable sport bikes under the XB series of Buell Motorcycles.
