V-twin
Angled engine configuration
A V-twin is an engine configuration with two cylinders arranged in a V shape, sharing a common crankshaft.
The design is iconic in motorcycles, particularly Harley-Davidsons, where the distinctive exhaust note comes from the V-twin's firing pattern.
The angle between cylinders varies—45 degrees in classic American bikes, 90 degrees in many Italian and Japanese designs.
The V-twin rumbled to life.
