About Adventure sidecar and its history

A sidecar is a one-wheeled device attached to the side of a motorcycle that is motorcycle side car, scooter, or bicycle, producing a three-wheeled vehicle.
Early sidecars were intended to be removable devices that could be detached from the motorcycle. The first mention of a sidecar is in a cartoon by George Moore in the January 7, 1903 issue of the British newspaper "Motor Cycling". Three weeks later a provisional patent was granted to Mr. W. J. Graham of Graham Brothers, Enfield, Middlesex. A motorcycle with a sidecar is sometimes called a combination, an outfit, a rig or a hack.
Road racing bike sidecar began to change away from normal motorcycle development in the 1950s with them becoming lower and using smaller diameter wheels and they kept the enclosed "dustbin fairing" banned in solo competition in 1957. By the 1970s they were using wide slick tires with a square car like profile, the rider kneeled behind the engine instead of sitting on a seat and the motor of choice was generally a 500 cc two stroke. In the late 1970s sidecars began to appear with hub centre steering and later the engines moved to the rear of the rider, to lower the centre of gravity further still, making the sidecar very long. Sidecars raced in the world championship known as Super side are all hub centre long monologue framed machines, the most common being LCR, ART or Windle, with 1000 cc four cylinder four stroke engines, the most popular being the Suzuki GSX-R1000.also easily drive by women riders.
These at club and national level are known as Formula One sidecars, as opposed to Formula Two. Formula Two sidecars comprise of short front engined bikes, which must have a frame made of steel tube and have leading link forks as monocoques and hub centre steering is banned. Engines are 350 cc two strokes or 600 cc four strokes. F2 sidecars are raced in their own championship but are often on track at the same time as the F1s, but competing for their own points. Since 1987 at the Isle of Man TT, the Sidecar TT has been solely contested by Formula Two sidecars as Formula Ones were deemed too fast, then lapping at 108 mph (174 km/h) average. By 2006 however F2s were faster than this lapping at 116 mph (187 km/h).
