CC refers to the engine displacement or in other words how big the motor is. Larger cc engines produce more power then a low cc engine can. When racing dirt bikes they require the engine size to be near the same size so that everyone has an equal chance in the race. For example: Racing a 125cc bike against a 500cc bike would be a one sided race. The 125cc bike would not have a chance against the power a 500cc bike puts out.
a dirt bike cc is a measurment for cubic centemeters
Its not a matter of age so much as a matter of size and ability. If the bike fits you go for it no matter what your age is.
1000 cc that i know of

A 111 cc dirt bike will go approximately 40 miles per hour. The exact maximum speed is dependent upon the manufacturer of the dirt bike.
Bigger cc = bigger motor = more power. But also heavier bike.
