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.
a 110 cc dirt bike goes around 40 or 50 up to 60 or 65 mph
a dirt bike cc is a measurment for cubic centemeters
a Honda xr650 max out about 180kmp/h
1000 cc that i know of
dirt bike motor
100cc the bigger the better
dirt bike i would look for a 200-300 cc street i would look for a 650-700
They can go from 65 - 75 mph ( Can reach 80, but I wouldnt try to go that fast)
with stock gearing should run 62-70 mph
Bigger cc = bigger motor = more power. But also heavier bike.
