Well, a 250. Unless if that 210 lb is fat. Then if you are fat, 125.
Yeah if they have the right size dirt bike and gear
a 120cc dirt bike is suitable for a 17 year old
A dirt bike can range from 100-300 pounds. It all depends on the size of the engine, the large 530cc bikes will weigh the most while the small 50cc bike will weigh the least.
You Should get the Diamondback Overdrive
A 90cc are 125cc 4stroke
The best way to determine the right bike is to go into a showroom so that you can check suitability of a seat height and engine size
Talk with a salesman, let them help determine what size dirt bike is appropriate for your. Be sure to tell them what you will be doing, play riding, racing, dual sport rides, etc. Select a model that is suitable for your skill level taking into account the bike's handling, power and size. Sit on the bike to make sure it is the right size and test ride each bike. Also, consider buying a used dirt bike.
A 50cc dirt bike doesn't technically have a weight limit. There are many full grown adults weighing in excess of 200 pounds which own and ride dirt bikes of this engine size.
If you can sit on the seat and stand flat footed on the ground.
There are different sizes for dirt bike wheels as there are for regular bike wheels.
