The 140 is a perfect choice. Once you have some experience and if you decide to race you can consider a different bike later.
I would have to say a 125cc. I am 15 6 2' 161 lbs and i can handle it with ease
look at the KX 100 its a in between size, I started on a 80, then moved to the 100.
O if you think that they can handle a 125 you could go with that its a little bigger and more powerful, but they will be able to ride it for years to come.
It all depends on the height of your legs and what speeds you can handle
To detmine what bike your feet should touch the ground
Also if it is your first bike get a 4 stroke b/c 2 strokes are race bikes and are hard to control
Yeah if they have the right size dirt bike and gear
between 150cc and 250cc
I would perfer a Honda CRF 50 there a very great 50cc training bike
a 120cc dirt bike is suitable for a 17 year old
For a 13 year old it depends on your size and your experience with dirt bikes, but an 85 is usually the best size bike and fastest for a 13 year old. Unless you are really tall which you would need a 125.
Dirt Rider magazine said that the dirt bike of the year was, KTM 350 SX-F
Try a Yamaha TTR 125 or CRF 150 (not the motocross version).
I have a ktm dirt bike trying to find out the year the number is ktm8701*45853*
what pipe? what dirt bike? what blaster? what year of dirt bike? what year of blaster? if they match up the same, yes. If they dont match up no.
the kawasaki dirt bike was invented by Jake mclister in 1994
Find the serial number on the engine, call up a motorsports place and they should be able to tell you what year the bike was made.
an 80cc dirt bike all of the BIG 4 make them
