I wonder who the 1st person in Japan was that said,"I want to trick out a Dodge van and race it."? How did it catch on? I've seen some similar videos posted here in the past.
The story goes that a guy and his friend had one each and would put their motorcycles in the back and drive to the race track. During the day, they were racing their motorcycles, but during lunch they had the idea to race their vans. They had so much fun and all the other motorcyclists loved watching it that it became a racing class.
