Ducati Superquadro engine

The Superquadro is a 90 degree V-twin four-stroke motorcycle engine made by Ducati since 2011. It keeps the Ducati desmodromic valve system, with four valves per cylinder and gear and chain driven double overhead camshafts, and it has been built in four displacements from 898 to 1,285 cc, with up to 145 kW (194 hp) in the largest version. It first appeared in the 1,198 cc 1199 Panigale of 2011 and was later used in the 899, 1299 and 959 Panigale models. Unlike the belt-driven overhead cams of earlier Ducati engines it uses gears and a chain, the engine is a stressed member of the frame, and its aluminium cylinders have Cermetal bore plating.
