A motorcycle is a two or three-wheeled motor vehicle steered by a handlebar from a saddle-style seat.
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.
A tricycle, sometimes abbreviated to trike, is a human-powered three-wheeled vehicle.
A sidecar is a one-wheeled device attached to the side of a motorcycle, scooter, or bicycle, making the whole a three-wheeled vehicle. A motorcycle with a sidecar is sometimes called a combination, an outfit, a rig or a hack.
Quadricycle refers to vehicles with four wheels.
A three-wheeler is a vehicle with three wheels. Some are motorized tricycles, which may be legally classed as motorcycles, while others are tricycles without a motor, some of which are human-powered vehicles and animal-powered vehicles.
A tilting three-wheeler, tilting trike, leaning trike, or even just tilter, is a three-wheeled vehicle and usually a narrow-track vehicle whose body and or wheels tilt in the direction of a turn. Such vehicles can corner without rolling over despite having a narrow axle track because they can balance some or all of the roll moment caused by centripetal acceleration with an opposite roll moment caused by gravity, as bicycles and motorcycles do. This also reduces the lateral acceleration experienced by the rider, which some find more comfortable than the alternative. The narrow profile can result in reduced aerodynamic drag and increased fuel efficiency. These types of vehicles have also been described as "man-wide vehicles" (MWV).
The history of the motorcycle begins in the second half of the 19th century. Motorcycles are descended from the "safety bicycle," a bicycle with front and rear wheels of the same size and a pedal crank mechanism to drive the rear wheel. Despite some early landmarks in its development, the motorcycle lacks a rigid pedigree that can be traced back to a single idea or machine. Instead, the idea seems to have occurred to numerous engineers and inventors around Europe at around the same time.
The following outline is provided as an overview of motorcycles and motorcycling:
In the Philippines, motorized tricycles, or simply tricycles, refer to a type of motorized vehicle consisting of a motorcycle and a passenger cab attached to it. Along with the jeepney, the Philippine tricycle is one of the most common means of public or private transportation in the country, especially in rural areas. These public utility vehicles either ply a set route or are for-hire, like taxis.
A motorized tricycle, motor trike, or motortrycle is a three-wheeled vehicle based on the same technology as a bicycle or motorcycle, and powered by an electric motor, motorcycle, scooter or car engine.
The Yamaha Tricity is a tilting three-wheeler motor scooter made by Yamaha Motor Company. It is part of Yamaha's LMW offering along with the Niken.
The Moto Guzzi 500 TriAlce is a three-wheeler Italian built by Moto Guzzi between 1940 and 1943 for the armed forces.
The Yamaha Niken is a 845 cc tilting three-wheeler motorcycle, manufactured since 2018 by Yamaha Motor and sold worldwide.
The Campagna V13R is a two-seat, three-wheeled motor vehicle produced by Campagna Motors since 2008.
