My New Bike

Motorcycle engines may be two-stroke or four-stroke, reciprocating or Wankel, single-cylinder or multicylinder (if reciprocating), or single-rotor or twin-rotor (if Wankel). The engine typically drives the rear wheel, but some small bikes such as the Velosolex have a friction drive to the front wheel. Most engines have a gearbox of between two and six ratios, and the Honda Gold Wing touring motorcycle has a reverse gear. Power is sent to the driven wheel by belt, chain or shaft. In Europe, up till the 1970 Honda CB750, engine capacities typically ranged from about 50 cc to 750 cc; but since then machines with capacities up to 2,300 cubic centimetres (140 cu in) Triumph Rocket 3 have become common. In the USA, motorcycles with large capacities have been common for much longer.
