                                                                  HOW DIRTBIKES HAVE EVOLVED           

 

 

In 1924 was when the first motocross race was held in Britain. It started in France and came over to Britain then to America. It was originally called scrabbling when it was getting started. The bikes where old and pretty much just a motor and a frame. The first   rear suspension came to motocross in the early 1930s. Suspension is a spring that is attached to the front and back wheel that makes the ride smoother and easier to control.  The motors where just 2stroke that ran off oil and gas mixed. The reason the oil was in the gas was to lube the pistons and everywhere the gas went it was oiled. One of the first bikes where a 500cc BSA, they used them for the military use in WW2. The people the road for BSA where the best in world  motor cross. After around 1957 a lot of people started making all kinds of different bikes, all different in there own way. In 1962 the 4-stroke was made a heavier bike but made up with it with having more power and “pull”. In 1966 motocross came to America it took off and the 4-stroke started to take over. But in the 1980s there was a thing called water-cooled bike before it  was air-cooled. If you where going slow the bike wouldn’t cool down and it would over heat. With the new water-cooled system that was more efficient but there are still the “old guys” that are air-cooled till they die. The 4-strokes and taking over in super cross to today. The makers of Suzuki invented a was to get a fuel injection in to a dirt bike. The fuel injection was originally of bullet bikes . in 2009 the bike was released to the public for use in races or  recreation use. The history of dirt bikes has improved a lot in the past century soon they will be flying.
