The Aprilia Pegaso was a desert and road motorcycle manufactured by Aprilia from 1989 as a replacement model for the Aprilia Tuareg and produced until 2011 under several displacements. It also was one of the first alternatives to the classic desert-road category.
The largest displacement model of the range was the Aprilia Pegaso 650, presented in 1992 as the first road enduro motorcycle with a double-spar aluminum frame. In 1997 and 2001, the bike received several changes, including a fuel injection system, different chassis measurements, and several mechanical modifications.
In 2004, at the Intermot show in Munich, the maker introduced a wholly renewed model offered in three different versions: the Pegaso 650 Strada, Pegaso 650 Trail, and Pegaso 650 Factory.
In 2006, the Italian motorcycle manufacturer launched the Aprilia Pegaso 650 Trail, an enduro-styled machine made more comfortable for long-distance riding and gliding on a 19-inch spoke wheel on the front with an aluminum rim and a 17-inch wheel on the rear.
The 2006 Aprilia Pegaso 650 Trail had installed a 659cc four-stroke liquid-cooled single-cylinder engine underneath its fuel tank, delivering an output power of 48 hp with a peak force at 6,250 rpm and 61 Nm (45 lb-ft) torque at 5,200 rpm.
The motorcycle's visual department had standard fittings, such as a high-mounted front fender, a small windscreen, a one-piece dual seat with a passenger grab rail, an engine cover, an under-seat-mounted exhaust system, and wire-spoke wheels.
