Aprilia RS 125

The RS 125 is the undisputed leader among 125 cc supersports. Aprilia has always led the field in lightweight sports bikes, pioneering new concepts and advanced solutions, and developing technology that others have had to struggle to follow. Like all Aprilia sports motorcycles, the RS 125 has benefited from the sophisticated technology that has been developed over years of success in GP racing, and quickly transferred into production. Over the years, the RS 125 has forged a reputation as the standard setter for sports 125’s. Sales success has come naturally too, with the RS 125 topping the sales tables on all European markets. The RS 125 is the inevitable choice of riders entering Sport Production racing. And rightly so, because when the competition gets tough, there is simply no other bike like the Aprilia RS 125.


The 2007 Aprilia RS 125 is designed and built for technical supremacy and has the looks to match. Its graphics are totally new and based entirely on those of the bike that dominated the 2006 250 GP world championship.


The Aprilia RS 125 gives young riders the best the market has to offer in terms of components and equipment, with a concentration of technical refinements that are not found on many superbikes.
