The Ducati Monster (called Il Mostro in Italian) is a muscle bike 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. The purposeful and considered use of 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. In 2005, Monster sales accounted for over half of Ducati's worldwide sales. Ducati motorcycles use almost exclusively 90° V-twin engines, which they call L-twins, with desmodromic valves, and tubular steel trellis frame, designed by Fabio Taglioni (1920–2001). The Monster line has had numerous variations over the years, from entry level 400CC (24 cu in) bikes up to top of the line 160 hp (120 kW) multivalve, water-cooled superbike-engined versions, with as many as nine different Monster versions in a single model year. The Monster's elemental simplicity has also made it a favorite platform for custom motorcycle builders, showcased at competitions like the Monster Challenge. Monsters eventually accounted for two-thirds or more of Ducati's output. In April 2010, the Monster 796 was announced, producing a factory-claimed 87 hp (65 kW). In November 2010, Ducati announced the Monster 1100 Evo, replacing the Monster 1100 and 1100s. The exhaust was moved to the side as opposed to underneath the seat, and the dry clutch changed for a wet clutch. Also, there was a change in the paint schemes. Another major change is the inclusion of Ducati Safety Package (DSP) which is standard with the motorcycle. This DSP consists of ABS and Ducati Traction Control. As of November 2010, the Ducati Monster family consists of the 659, 696, 796 and 1100 Evo. In October 2011, Ducati unveiled a new addition to the Monster family, the 795. Essentially a 696 frame with the larger 803CC engine from the 796, the 795 is aimed specifically at the Asian market and will be assembled in a plant in Thailand. In November 2013 at EICMA, Ducati introduced the 2014 Monster 1200 and 1200 S, with a watercooled four valve 135/145 hp 1198 Testastretta 11 engine. It replaced the Monster 1100 Evo. As of January 2014, the Ducati Monster family consists of the 695, 696, 796, 1200 and 1200 S. The 796 was replaced by the Monster 821 in mid 2014, equipped with the 821CC Testastretta from the hyper line, and incorporating the same electronics suite as the monster 1200. For 2016 the monster family has come to include a new model the Monster 1200 R. Claimed to be the most powerful Monster ever and more track oriented. With 160 hp (120 kW) (claimed) 15 more hp than the Monster 1200 S and with 97 lb·ft (132 N·m) of torque. It is the same Testastretta 11° DS, 90-degree V-twin used in the Multistrada and Diavel. It has Öhlins suspension front and rear and a 1,509 mm (59.4 in) wheelbase compared to 1,511 mm (59.5 in) for the S model. With a claimed wet weight of 207 kg (456 lb) it also boasts a 200-section over the 1200 S’s 190 rear tire. On September 21, 2008, a gathering of Ducati Monsters in Hamme-Moerzeke, Belgium, broke the Guinness Record for the "largest parade of motorcycles of the same brand and type." 405 Ducati Monsters were tallied.
