For 2013 the RX 50 continued as a carry-over model: the same 49.9 cc liquid-cooled two-stroke, six-speed gearbox and steel-framed enduro chassis with full-size wire wheels. It remained the entry point to Aprilia's off-road range for 14 to 16 year-old riders, with the changes limited to colours and decals.
