Desmodromic valve actuation has been applied to top-of-the-range production Ducati motorcycles since 1968, with the introduction of the "widecase" Mark 3 single cylinders. In 1959 the Maserati brothers introduced one of their final designs: a desmodromic four-cylinder, 2000cc engine for their last O.S.C.A. Barchetta.
Motorcycles with a V-twin engine mounted with its crankshaft mounted in line with the frame, e.g. the Honda CX series, are said to have "transverse" engines, [1] [2] while motorcycles with a V-twin mounted with its crankshaft mounted perpendicular to the frame, e.g. most Harley-Davidsons, are said to have "longitudinal" engines.

The J-series is a 60° V6 unlike Honda's existing 90° C-series engines. Also unlike the C series, the J-series was specifically and only designed for transverse mounting. It has a shorter bore spacing (98 mm (3.86 in)), shorter connecting rods and a special smaller crankshaft than the C-series to reduce its size.
Honda itself at first denied there was a problem, then blamed inadequate or incorrect maintenance for the problem. They changed the maintenance interval, and developed and sold a special tool for 'proper' valve-lash adjustment. They eventually made changes to the design and production methods of the engine which eliminated the problem.
The Ducati Superquadro engine is a 90° V-twin four-stroke motorcycle engine made by Ducati since 2011. It has Ducati's signature desmodromic valve system, with four valves per cylinder and gear/chain driven double overhead camshafts .
