Enduro Dirt Bikes

I want to know if I can drive a motorcycle off-road enduro leagaly in California 15 years

On private property, all ... If this is the type of bike you ride on the street, you'd need a license, and you need it to 15.5.

Yes, if you can spell correctly

not sure on age, but I know ......" Baha "is a kit that is, I think $ 500 which will make most legal enduro (I think everything is two lights and a few other things):)
