If you know motorcycle racing, you know the Red Bull Rookies Cup feeds the Moto3 World Championship, which eventually feeds the MotoGP grid. But long before riders ever make it to the Red Bull Rookies Cup, they're competing in the MotoMiniGP. It's mini by name, but not by nature.
The MotoMini World Series is essentially the first step on the ladder to MotoGP, as the classes and machines are standardized. At the moment, there are two classes: the MotoMini 160 and the MotoMini 190. The MotoMini 160 consists of riders aged 10-14 years old on Ohvale GP-0 160 bikes, while the MotoMini 190 is for riders aged 12-16 years old on Ohvale GP-2 190 Daytona machines.
