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
They are excelent bikes, fun, easy to ride and good for teenagers.
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.
I personally think the dirt bikes with the wider wheels are the best
