Pit bikes, scooters and mini bikes

One of the pleasures of rally and races is seeing what people use to get around the arena with. Some have ful size Vtwin in min bike size contructions by most are kids type cycles. Show what ya got or seen here. I got a 2.5 hp mini DuddleBug that would not climb my slight grass grade in yard to tried a vapor carb and dang if it didn't work to power up grades and go too fast w/o suspension off pavement. I reccomend a mini or cycle with some suspension if used off parking lots.
