Ok guys i need help wat size of pit bike would be good for me im 4"11 and i would like to know wat size is?

Question

better for me a 110cc pit biek or a 120cc

Answer 1

Not that big of a difference between the two really. Some 110's are faster than the 125's and they are all close in physical size. Basically no matter which size engine you get there is generally a choice of either a 12" or 14" rear wheel.  

Answer 2

You can only ride it in your yard so it doesn't matter you do not have enough room to really get going.  

Answer 3

Dont you anything better to think  about .You will notice no difference.
