2005 Ducati Monster 620

Ducati introduced the S4, which added the liquid-cooled four-valve Superbike engine to the stable. Other technical changes that year included semi-floating front disc brakes with Brembo four-piston calipers, lighter Brembo wheels as well as 43 mm Showa inverted forks.

Ducati added the S2R Desmodue (two-valved Desmodromic engine) line to the Monster family: styled akin to the four-valve S4R, but with the simpler two-valve 800 cc and 1,000 cc motors in the S2R 800 and S2R 1000, respectively. February 2006 marked the announcement of the 2007 Monster 695.

Ducati sold over 12,000 696 models, the first of their motorcycles to sell over 10,000 bikes in one year. The 1100 S model has fully adjustable Öhlins suspension components, a different colour scheme and aluminium brake disc carriers, which account for a 1 kg weight reduction.
