Ducati Monster 821

The Ducati Monster (called Il Mostro in Italian[4]) is a muscle bike[5][6] designed by Miguel Angel Galluzzi and produced by Ducati in Bologna, Italy, since 1993. It is a naked bike, characterized by an exposed engine and frame.[1][2][3] The trellis frame in the Ducati Monster is an integral part of the motorcycle's design allowing for both aesthetic appeal and for structural efficiency.[7] In 2005, Monster sales accounted for over half of Ducati's worldwide sales. Ducati motorcycles use 90° V-twin engines, which they call L-twins, with desmodromic valves, and tubular steel trellis frame, designed by Fabio Taglioni (1920–2001).
