Call it a motorcycle, call it a scooter, the Aprilia RS50 can be both of them. The aluminum frame, the aluminum swing arm, lightweight wheels with ‘Y’ spokes, radial caliper front brake, two-stroke engine, fairing based on that of the RSV 1000 R, are some of its main features. All of these plus the 50cc engine make it go as fast as 50 mph, but if you get rid of the electronic limitation you can cruise with 80 mph.
