Laws regarding the operation of pit bikes or dirt bikes on public roads vary by country and jurisdiction. In general, operating a street-legal pit bike or dirt bike, such as the SSR 110, would typically require a motorcycle license or endorsement, just like any other street-legal motorcycle.
These smaller motorcycles may be designed for off-road use primarily, but if they are street-legal and intended for use on public roads, they are subject to the same rules and regulations as larger motorcycles. This usually includes the requirement for a valid motorcycle license or endorsement.
To get accurate information regarding the specific laws and licensing requirements in your area, it's best to consult the local department of motor vehicles (DMV) or relevant regulatory authorities. They can provide you with the most up-to-date and accurate information regarding the licensing requirements for operating a street-legal pit bike or dirt bike on public roads.
