A scooter is a form of motorcycle with a step-through frame and a platform for the operator's feet. Elements of scooter design have been present in some of the earliest motorcycles, and motorcycles identifiable as scooters have been made from 1914 or earlier.
Most people have heard of Vespa or Lambretta, which became a popular form of transportation after World War II. Engine sizes range usually from 50 cc to 250cc, making them cheaper on insurance than motorbikes.
