Aprilia RS 125 versus Yamaha YZF-R125

Brief introduction to the Aprilia RS 125


54 world titles, hundreds of wins in MotoGP, SBK and Offroad: Aprilia is the most successful European brand in the history of motorcycling among those still active.


With a racing team that has pioneered ideas and technologies that has always sought new challenges: from MotoGP to Motocross, from Superbike to Supermotard, from Rally to Trial, Aprilia shares passion, challenges and victories. The same winning emotions that Aprilia shares every day with riders on roads and racetracks around the world. The Aprilia RS 125's new look takes its inspiration from the shapes and colours of its multiple title winning older sister, the RSV4 that is a protagonist in World SBK, an aggressive and original look that is high lighted by the triple headlight, a trademark of the "big sister".


The sleek fairing enhances the exclusive aluminium frame, an entirely racing-inspired refinement that no competitor can claim. A winning solution that Aprilia takes from its experience on the track to reduce weight and bulk and give the vehicle text book agility and handling.

The tapering lines of the slender tail fairing seem to melt away into nothing, joined together with the LED taillight that, in the spirit of road safety, guarantees outstanding lighting power. The new RS 125 version is available in two liveries: Silver Speed and Black Speed. Both with a sporty orientation, they are also characterised by the graphics with the dominating "a" on a red background which is the emblem of the Aprilia machines that compete on racetracks all over the world.

The graphics on the fuel tank recall the Italian red, white and green as a reminder of the RS 125's exclusivity, the only small sport bike to be designed, developed and built in Italy. The latest version of the Aprilia RS 125 also boasts the largest storage compartment in its segment, a space that can hold a 6" tablet. A practical USB port can also be mounted to conveniently recharge your smart phone or any other compatible device.

There is also the Aprilia RS 125 Race Replica.
