styling of the RS is based on that of the RSV 1000 R and, as with all Aprilia sports bikes, is the result of painstaking aerodynamic research. The new fairing, for example, was perfected by extensive wind tunnel testing, to guarantee GP class wind protection and minimum drag, and to obtain maximum racetrack efficiency from the small engine. The fairing, windshield and tail not only look mean and aggressive, but allow the RS 125 to reach a blistering top speed, eliminating the turbulence that can disturb rider concentration. Man and machine really can become one when the machine in question is an Aprilia RS 125.

The latest generation twin halogen headlight also adds to the mean look of the new RS, and delivers a high power light beam for enhanced visibility and safety at night.

The sleek tail also houses a new light cluster with a pure racing look. In fact, a great deal of effort has been put into all aspects of design of the RS 125 tail. As a result, the passenger seat integrates perfectly with the silhouette of the bike.

Because the new, crossed spoke wheel design is lighter, more reliable and safer, it also improves sports performance.
