Aprilia RX

The Aprilia RX is an Enduro motorcycle widely produced by Aprilia. It is powered by a six-speed, carburetor-fuelled, nikasil-lined and cast iron single-cylinder two-stroke engine manufactured by Derbi/Piaggio.

Styling and concept

The 2006 Aprilia RX is the renovated successors of the Aprilia RX first produced in 1992; the panels and layout are based closely on the bigger displacement Aprilia RXV/SXVs.

Engine

The engine in the Aprilia RX 50 is sourced from Derbi/Piaggio. 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, although 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
