Motorcycles are motorized vehicles for transporting one or two riders. Generally, a motorcycle has only two wheels, but any vehicle with fewer than four wheels in contact with the ground can be classified as a motorcycle. Three-wheel variations of the motorcycle include the "hack" (motorcycle plus sidecar) and the "trike" (short for motortricycle).
The layout of the modern motorcycle was established by 1914 and has remained fundamentally unchanged ever since. The overall structure and function of a motorcycle is quite simple. It includes a gasoline engine, which converts the reciprocating motion of pistons into rotary motion, just like the engine in a car. A transmission system transmits this motion to the back wheel. As the back wheel turns, it propels the motorcycle forward. Steering is accomplished by turning the front wheel via the handlebars and by leaning the bike to one side or the other. Two hand levers enable the rider to operate the clutch and the front brake, while two foot pedals enable him to change gears and control the rear brake.

In 1988 Honda introduced to their demanding cruiser customers the dream of sheer luxury in motorcycling the new 1520 cc Goldwing.
A flat six engine similar to that fitted to an earlier machine in the early 70's produced the power required to satisfy its customers.
Standard equipment fitted included, cruise control, radio cassette with speaker units for the pillion passenger, heater vents, on board compressor to pump up the rear suspension and a facility to attach an air hose and inflate the bikes tyres and the icing on the cake a reverse gear worked off the electrical system by firstly engaging the reverse lever then pressing the starter button and the bike will shunt backwards at slow speed. Fully fuelled the GL 1500 weighs 880lbs.
