How come are dirt bikes not allowed to ride on paved roads?
No blinkers, no headlights, no brake lights,not quiet,not
Many dirt bikes are also street bikes. In fact, I know that Yamaha makes several, as my father has one. Those are legal, but I think they have to be approved. And you still have to get a motorcycle licence.
As far as dirt bikes, such as mine (Kawasaki KLX110) you would most likely be told to not ride that on the road.
