Linked to the bigger sisters of the SXV and RXV, the little ones from Aprilia for new licence holders were going to be successful from the start. And so it has occurred with the Aprilia SX and RX 125 entering 2009 as heirs to the specialist enduro experience of Aprilia.
The design is perfect for this kind of bike, along with just enough power for a 16-year old to safely enjoy a motorcycle. The difference between the SX and RX versions are mostly in the wheels, suited to road or terrain use accordingly.
Details include a two-stroke, single cylinder 125cc engine, front floating 260mm disc brake and rear at 220mm, double cradle frame and upside 40mm fork.
