Storm Riders

Storm Riders are the term used to describe individuals (mainly gangs) that use A-Ts regularly to take part in parts wars or generally cause trouble. Storm Riders can either ride solo (in which they can only make it up to D-Class in a Parts War) or ride in a Storm Rider team (e.g Kogarasumaru) that can reach the maximum level of A-Class in a parts war.

History
When the first few A-T's were bought, everyone usually used them to have fun and chill out with each other, it was only a matter of time before people started using A-T's for the wrong reasons. Sooner or later people started forming gangs with filled with Storm Riders and eventually things like the Parts War network developed from being small time parts trading to large scale competitions all over the world.
