The 1st patented motorcycle was made in 1900 by the Werner brothers. In 1885 Gottlieb Daimler and Wilhelm Maybech created the 1st petroleum powered vehicle which was also a dirtbike/motorcycle. Motorcycles were improved frequently up until the present day. This all leads to my favorite sport(to watch) which is motocross. Motocross started in 1970 for fun mostly, but today its very competitive. Races you usually go for 35 minutes plus 2 laps.

First double backflip done by Travis Pastrana. Who is a stud at everything that has a motor and you can race it.
