The RS50 is a sport moped, GP derived replica sport production motorcycle made by Aprilia.^[1] It is powered by a single cylinder 2-stroke aluminium cylinder block, liquid cooled 49.9 cc (3.05 cu in) Motori-Minarelli AM6 engine. The bike is popular in countries that have restrictions on motorcycle engine size. In restricted form the RS50 is capable of speeds of 50 km/h (30 mph), in derestricted form the motorcycle is capable of speed up to 105 km/h (65 mph).^[1] This and other similar machines such as the Derbi GPR 50 and Yamaha TZR50 have also been popular choices as a more adult-sized option for MiniGP racing, which is otherwise more commonly participated in by riders of smaller bikes such as the Honda NSR50.
