yZ 450cc with a pro tapper pickin pocker is exhausht is what i started with in i was 13. i now ride a Kx 993cc its a bad bike and it flies.
Kawasaki is the best 125cc dirt bike. Hopefully this link will helps you.
Yamaha TTR125 is the best dirt bike. I think it’s 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"
The best dirt bike for kids is no bigger than a 100cc
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..
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
