A stroke is the action of a piston travelling the full length of its cylinder.In a two-stroke engine, one of the two strokes combines primarily the intake stroke and the combustion stroke, while the other stroke primarily combines the compression stroke and the exhaust stroke, though technically since both ports are exposed during both the combustion and compression strokes, some reversion ...
A "long bang" inline 4 engine fires both pairs of cylinders in quick succession or simultaneously; the power delivery is identical to a parallel twin with a 180° crank and similar to a V-twin. In 2005 Kawasaki experimented with this configuration on the ZX-RR MotoGP bike.
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.
V-twin engines have the following characteristics: With a V angle of 90 degrees and offset crank pins, a V-twin engine can have perfect primary balance. If a shared crank pin is used (such as in a Ducati V-twin engine), the 360° crankshaft results in an uneven firing interval.
A V-twin engine, also called a V2 engine, is a two-cylinder piston engine where the cylinders are arranged in a V configuration and share a common crankshaft. The V-twin is widely associated with motorcycles, primarily installed longitudinally, though also transversely. They are also used in a variety of other land, air, and marine vehicles, as ...

An early experimental 200 hp Clerget V-8 from the 1910s used a sliding camshaft to change the valve timing [citation needed]. Some versions of the Bristol Jupiter radial engine of the early 1920s incorporated variable valve timing gear, mainly to vary the inlet valve timing in connection with higher compression ratios.

Kawasaki Vulcan The VN750 , also known as the Vulcan 750 , is a 750 cc class cruiser -style motorcycle made by Kawasaki from 1985 to 2006. The Vulcan 750 was Kawasaki's first cruiser and first V-twin engine , introduced in late 1984 as the 1985 model.
