as fast as my mom makes me roti
it all dipends on the bike
My grandpa can get his up to almost 17 mph!
Probs about 60 - 70 mph
a 110cc dirt bike is just like a 50cc just a tiny bit bigger and is probaly 50mph at the most
70ish
40
55 to 60 its fast
70 to 80
45
I think about 40 mph.
Depends what kind it is, what brand, if it is four or two stroke. depends on a lot of things but you must look at many different sites to see how fast
It depends on if it's a Chinese engine (slow) and not including Honda. If it's a real Japanese engine it should go around 70-85mph i have a 110cc engine that can hit around 60-65.
