Jump on one of the bikes and let’s race. If you want to continue and proceed into the next round you have to finish at least third.
Fine looking racing game with five circuits, various bikes and money you can spend on more things. What the game hasn’t is a nice graphics and animation which could be overlooked but I couldn’t understand the racing system. To unlock a new race you have to finish third worst but when you repeat some old race the next races are unlocked again.
