DOT laws vary by state, but for the most part minibikes are illegal for use on public roadways since most do not carry the necessary equipment (and often size requirements) to be street legal. In many states the seat of a motorcycle must be at least 25 inches (64 cm) off the ground, which is often a limiting factor in registration. Usage on public roadways may result a number of offences,[1] including but not limited to: no indicator lights, no rearview mirror, no horn or signaling device, no headlight, too-small muffler (noise pollution), improper lane change (no blinkers), or reckless driving.
Some of the larger "super" pocket bikes, most commonly the X18, X19, and X22 meet all the requirements and can be registered for legal street use in most US states. These bikes have headlights, turn signals, tail/brake lights, a horn, and speedometer, and can also do the speed limit in most scenarios (typically 4 stroke bikes can reach speeds of 55 mph). In many states all one needs to do is add a rearview mirror and a license plate bracket, but it is best to check with local DMV authorities for exact requirements. In some cases, if the bike requires minor modification to meet requirements, one may be able to register it as a "unique/homebuilt." The "super" pocket bikes typically are FMVSS certified. Frequently, a Manufacturer's Statement of Origin is required for registration.
Like a full-size motorcycle, the rider must carry insurance, have a current inspection, and wear a helmet if local laws require it. Depending on if the state classes a pocketbike as a "moped" or full "motorcycle", the rider may or may not need a special motorcycle license. If not, a regular driver's license may suffice.
