550-Mile 2004 Ducati Monster S4R

This pristine 2004 Ducati Monster S4R shows only 550 miles and hasn't been registered outside its Scottsdale showroom debut. Its blue steel trellis frame, color-matched flyscreen, and carbon-fiber fender distinguish it among classic Italian sportbikes, powered by a liquid-cooled 996cc L-twin engine paired with a six-speed transmission.
