Styling and concept
The 2006 Aprilia RX/SX 50s are the renovated successors of the Aprilia RX 50 first produced in 1992;[1] the panels and layout are based closely on the bigger displacement Aprilia RXV/SXVs.
Engine
The engine in the Aprilia SX 50 is sourced from Derbi/Piaggio (D50B0/D50B1). This engine is used in the Derbi Senda DRD/X-Race/X-Treme supermotos and crossers, as well as the 2006 onwards Derbi GPR 50 and Aprilia RS 50 road bikes, altough the road bikes feature an electric starter instead of a kickstarter on the supermotos. Engine parts from the crossers and supermotos can be directly swapped with one another; there are some small differences between the road bike and supermoto engine and frame which may require modification to transfer some external engine parts (exhaust, airbox etc.)

Le Aprilia RX sono le motociclette enduro/fuoristrada della casa di Noale, sono molto simili ai modelli da Cross ma con un impianto elettrico che comprende anche i fari, frecce, stop e varie spie, come la spia dell'olio, inoltre hanno anche uno specchietto retrovisore, un rubinetto della benzina con la riserva, il miscelatore per la lubrificazione separata e ovviamente la targa. I modelli sono prodotti nelle cilindrate di 50 e 125 cm³ e si piazzano tra le moto da enduro e le fuoristrada, prima che la versione 125 venisse depotenziata.
