The V-twin is a V-shaped engine with two cylinders and has been used on motorcycles for the last 100 years. The parallel twin, on the other hand, is another name for a straight-twin engine, meaning that the cylinders are in line, positioned one behind another above the crankshaft, with a firing order of 360°, 180° or 270°. Manufacturers such as Harley-Davidson, Indian and Victory use the transversely-mounted V-twin for their cruisers and touring bikes. Whereas, parallel-twin engines have been used by Triumph and other British manufacturers. Moreover, from the 1960s to the 1980s, Japanese manufacturers like Honda, Yamaha, Suzuki, and Kawasaki also adopted the parallel-twin engine. Parallel twins can be more compact than the V-twin engine alternative, cheaper to produce and occasionally, easier to service and maintain.
