True vs V-2

There is some ambiguity what defines a V-twin arose from 180 degree V (see Flat engine ). the cylinders are arranged in a V pattern, it is accepted as being a V engine. some people differentiate V-twin to mean the classic V of a shared crank pin for each of cylinders and V-2 to indicate a boxer crank with a separate pin for each cylinder. This is not common, and applies only to two engines.

For example, while V8 engines use shared crank for cylinder pairs, they are not to as V-octuplets. Most engine do not use this convention and the 1983 Shadow 750 is known as being the V-twin with an offset-dual-pin [ 1 ]

V angles

Generally, any two-cylinder engine with its two cylinders at an opposite angles from the rotation of the crankshaft is referred to as a The V-twin engine is not designated by a angle, but people associate the 45° engine with the classic configuration. While any motorcycle can a v-twin engine, cruiser motorcycles most commonly use configuration.

For example, Honda a 52° engine in several of their motorcycles. But other angles can be such as the 75° Suzuki and KTM. the 80° CX-500. the 47° Vincent. and the 60° Aprilia. The manufacturer SS offers a 45° and a 56.25° for use in custom choppers.

A 90° twin engine, such as the Ducati engine and recent engines — with the front approximately parallel to the ground and the cylinder vertical — is generally to as a L-twin engine. There is no distinction between V-twin and engines. These are merely used by convention.

From an perspective, the 90° angle is preferred as it as a counterweight to balance the engine.

The terms longitudinal and transverse engine are most used to refer to the crankshaft [ 2 ] [ 3 ] however, some sources, prominently Moto Guzzi. use the in the opposite way.

A Moto Technical Services representative to explain to LA Times columnist Carpenter that Moto engines are called ‘transverse’ the engine is mounted with the oriented front to back of left to right. [ 4 ] In spite of it it could be assumed that who call V-twin motorcycle transverse when they are with the crankshaft front-to-back and the sticking out the sides are saying to them, the engine’s axis is the passing from one cylinder to the at a right angle to the crankshaft, than going by the crankshaft’s [ 5 ] [ 6 ] [ 7 ] [ 8 ] [ 9 ] [ 10 ] [ 11 ] Highly technical sources, as V. Cossleter’s Motorcycle Dynamics . [ 2 ] or Cocco’s Motorcycle Design and [ 12 ] are careful to not simply use the terms engine or transverse engine, but to specify that they the engine’s orientation based on the and so they will say transverse engine or longitudinal crankshaft

Transverse crankshaft mounting

The can be mounted in transverse crankshaft as on Harley-Davidsons. Ducatis and many Japanese motorcycles. This position gives the motorcycle a frontal area. The main of this configuration is that the cylinder and the front cylinder receive different air-flows air cooling somewhat problematic for the rear cylinder.

Cooling are somewhat mitigated by having all sides of each cylinder to air flow. This differs a parallel-twin cylinder engine has a distinct front, back, and but the inside of each cylinder is not to airflow as the cylinders are typically together with a cam chain up through the block in-between the
