Scooter Developments
As we all known, air pollution is rapidly increasing to dangerous levels. Therefore, the government and the technological industrial fields are making an effort to apply new technology, fuel cell technology, for developing environmentally friendly scooters.
Three-wheeled scooters
During World War II, Cushman made the Model 39, a three-wheeled utility scooter with a large storage bin between the front wheels. They sold 606 to the US military during the war. The Piaggio MP3 is a recent example of a three-wheeled scooter. Unlike most motorcycle trikes, it has two front wheels, with tilting suspension to allow the body to lean when cornering, like a two-wheeled motorcycle.
Maxi-scooter
A maxi-scooter or touring scooter is a large scooter, with engines ranging in size from 250 to 850 cc (15 to 52 cu in), and using larger frames than normal scooters. A new direction in maxi-scooters has the engine fixed to the frame. This arrangement improves handling by allowing bigger wheels and less unsprung weight, also tending to move the centre of gravity forwards. The trend toward larger, more powerful scooters with fully automatic transmissions converges with an emerging trend in motorcycle design that foreshadows automatic transmission motorcycles with on-board storage. Examples include the Aprilia Mana 850 automatic-transmission motorcycle and the Honda NC700D Integra, which is a scooter built on a motorcycle platform.
Electric scooters
Generally, the source of power for the electric motor has been batteries, but development in fuel cell technology has created several prototypes. Some examples are: the ENV from Intelligent Energy, Honda's scooter using the Honda FC Stack, and the Yamaha FC-AQEL. Also, petroleum hybrid-electric motorcycles are available. Some examples are the Ecycle, and Yamaha's Gen-RYU. Electric motorcycles and scooters are rising in popularity because of higher gasoline prices. Battery technology is gradually improving making this form of transportation more practical.
Anyhow, scooters are becoming more and more common, and more and more people pay attention to the scooter maintenance, but lots of people have not know the easiest way. That is scooter cover.
