In vintage Mini Bike racing riders race classic Mini Bikes that are no longer competitive with the latest production Mini Bikes. Classes are organized by production period and engine displacement. Equipment is limited to that available for the production period, although modern safety equipment and tires are permitted. Most vintage production periods are from the 1970s and before, but now 1980s Mini Bikes are being allowed into most events. Generally a Mini -Bike must be at least 25 years old to be considered vintage.
