ApriliaRS 125

Description

Aprilia has always been the undisputed leader in 125 cc supersports, a market segment in which Aprilia has pioneered new concepts and advanced solutions, and developed technology that others have struggled to follow. Like all Aprilia 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 major 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 Aprilia RS 125 offers young riders the best in components and equipment, and a concentration of technical refinements worthy of a flagship supersport.
