From Wikipedia, the free encyclopedia
An Inline-twin, inline twin-cylinder, or in-line vertical-twin[1] is an internal combustion engine in which the axis of the crankshaft is inline with axis of the final drive or chassis of the vehicle.[2] It is also known as "in-line" and tandem twin. An inline-twin engine differs from the two cylinder engine design known as a parallel-twin engine which has its crankshaft at a transverse or right angle to final drive and the chassis of the vehicle.[3] An inline-twin, having its crankshaft parallel to the direction of the chassis or drive, is described as being longitudinal, hence the differentiation between transverse and longitudinal parallel twins.[3]
