Supermini (motocross class)

Supermini is a motocross racing class for young riders moving up from 85 cc bikes but not yet ready for full-size 125 cc and 250 cc machines. In American amateur racing it typically covers two-strokes of around 85–112 cc and small four-strokes, on big-wheel minicross chassis.

Class rules differ between countries and organisers, so displacement limits and age ranges vary. In Europe the more common steps are 65 cc, 85 cc and then 125 cc two-strokes or 250 cc four-strokes.
