The 2006 Aprilia RX/SX 50s are the renovated predecessors of the Aprilia RX 50 first produced in 1992; the panels and layout are based closely on the bigger displacement Aprilia RXV/SXVs.
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. 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.)
