An underground group of armed and dangerous sport bike riders in and around the Kansas City area. They are well know by their symbol ( a small rocket logo) that they wear proudly on jackets, gloves,boots, t-shirts, sweatshirts,socks, ball caps. Rocket Riders are known to ride their bullet bikes with illegal, gang related intent. 
Those Rocket Riders are no good... They stole my girlfriend and slapped my Mother.
