Its more about your riding ability than a set age. If you can physically handle the bike and have confidence with it, go for it.

No we can't use 100cc 4 -stroke dirt bike race against 85cc dirt bikes.
125 or 250 if you fit on the but but they run together in the 250 class
16-18 at minimum. ^ retard. An 85cc bike is WAY to small for any 16-18 year old. Most 16 year old racers I know race in the 125cc 2t/ 250cc 4t class. And by the time you hit 18 you start to see alot of kids that age enter the 250cc 2t/ 450cc 4t class. I would say around the age of 10 if you want to race in the 85cc class.
