How do Scooters differ from Motorcycles?
By definition, motorcycles are nearly any two-wheeled, motorized vehicle. Therefore, scooters are by definition simply a specific motorcycle design. This is why in most localities, there are no regulations for scooters per se, and thus scooters fall either under moped regulations (assuming they meet the proper requirements to do so) or by default, they are legally treated as motorcycles. There are a few localities that have specific regulations for scooters, but as these are extremely uncommon and follow no real pattern, they are not covered here. The reason that scooters are commonly not treated as equals in motorcycle circles is simply because they generally are slower and not as performance-oriented as their larger cousins. So technically, all scooters are motorcycles, though usually only scooters that more closely resemble what are more commonly called motorcycles will be referred to as such.
