The fastest dirt bike ever was the Honda CrF450r. This bike had a four stroke engine liquid cooled that could produce 499cc.
I think Travis Pastrana. He did the first double back flip ever!!
very fast no it bout 130
Kawasaki is the best 125cc dirt bike. Hopefully this link will helps you.
Yamaha TTR125 is the best dirt bike. I think itβs a good idea for a beginner to use a dirt bike with low engine power. Yamaha TTR is a perfect mid-size beginner bike; it has a 124 CC engine with four strokes.
if you want a bike for trails and dirt go for an eastern trail digger or a fit bike
the best dirt bike would be a 250cc 2 stroke
Suzuki DRZ 125 is best dirt bike ever.
12"
as far as I think..and my personal. view I will suggest you to go for YAMAHA,KAWASAKHI...dirt bike of these company are best..
The best dirt bike for kids is no bigger than a 100cc
either a kawasaki ktm Yamaha Honda
The best dirt bike for a would be a Honda CRF 100 for a male and a CRF 70 for a girl. Of course the real size of the bike depends on the size and experience of the rider.
