kx 250f.

The size or displacement of the engine, 50cc versus 125cc.
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.
i do not think there is a 2006 crf150r
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
depends on how tall and what your weight is. if your average or a bit above it for your age, a HONDA XR100 will do nicely.
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..
Seized engine?
