a racing 2stroke dirt bike
Kawasaki is the best 125cc dirt bike. Hopefully this link will helps you.
The size or displacement of the engine, 50cc versus 125cc.
if you have a 4stroke dirt bike you run straight gas ,if you have a 2stroke dirt bike you run mixed gas
yes the 125 with the 80 frame is goin to go a little bit faster because it is light it probaly feels like it has more torque too because it will pop up wheelies faster but probaly the 125 with the cr 80 frame.
im not sure about that but i can say that a 2 stroke 125cc is faster than a 125cc 4 stroke and probably 200cc too. a 125cc 2 stroke would throw you off the back if you cant handle it properly, where as the 4 stroke wouldn't scare the living daylights out of you
there are no age limits for dirt bike. but there are recomendations for size
no not in most cases unless it was geared verry high like where some one had to push you to get going if it was stalk gear ratio no possible way
My son and me both have one and can get 50mph on dirt .
No. That's a motorcycle. Motorcycle are to be ridden with the cars.
