Do you need a motorcycle license to ride the xingyue 150 cc motorcycle in Arizona?

Answer 1

Yes, per the Arizona MVD. Any motorized cycle requires a class M licence or endorsement. However any cycle with an engine under 50cc of displacement, and a top speed under 25mph classifies as a moped (even if it has no petals), and only requires a standard drivers license. The basic rule here is "if it goes fast enough to ride it in traffic, you need a license to drive it"

Answer 2

Mopeds have a two-stroke engine that propels the vehicle to speeds of 30 mph, but they're not considered motor vehicles in Hawaii. Furthermore, Hawaii does require all owners to register their moped and display the decal prominently on the fenders. There is one catch, however―you must register the moped as a bicycle. Although this may sound strange it can be an advantage for you because (1) the registration fee is cheaper ($15), (2) a helmet is not required, and (3) you do not have to purchase insurance to operate the moped on public roads. You will, however, have to get the moped inspected annually. Hawaii defines a motor scooter as a two-wheel vehicle with an engine under five horsepower. Thus, if it has a four-stroke engine it automatically falls into the scooter class. Of course, some scooters have more horsepower and still carry many scooter features. Hawaii puts these vehicles in the motorcycle category. Thus, if you mod your Vespa too much, you might end up in a different category of vehicle. Not that this matters much. In Hawaii a motor scooter must go through the same registration process as a motorcycle. Also, the laws for scooters and motorcycles are essentially the same. This means to ride a scooter in Hawaii you must obtain a motorcycle-class license, wear a helmet, and have the proper insurance. information was taken from http://www.dmv.org/
