Motorcycle design varies greatly to suit a range of different purposes: long distance travel, commuting, cruising, sport including racing, and off-road riding. A motorcycle has more than a 150cc engine size, and no more than three wheels; it has to be registered and the driver must have a motorcycle license (M1) but can also  operate any motorized bicycle, moped or motor scooter without an M2 endorsement.

Popular motorcycle brands include BMW, Honda, Ducati, Yamaha Motor Company, Honda Motor Company, Kawasaki Heavy Industries, Triumph, Suzuki Motor Corporation, Aprilia, KTM, Moto Guzzi, Harley-Davidson Motor Company, Royal Enfield, MV Agusta, Norton Motorcycle Company, Benelli, Hyosung, Indian Motorcycle Manufacturing Company, Bimota, Victory Motorcycles, Kymco, Husqvarna Motorcycles, Hero Motorcorp, Arctic Cat Inc., Blata, Audi, Buell Motorcycle Company, Cagiva, Maico, Adler, Derbi, TVS Motor Company, Janus Motorcycles, Cleveland CycleWorks, and Peugeot.

A motorized bicycle or moped is a two- or three-wheeled device, capable of no more than 30 mph on level ground, and equipped with fully operative pedals for human propulsion, a motor producing less than two gross brake horsepower and an automatic transmission, and an electric motor. The driver must have a motorcycle license.
