| Aprilia's profilation of this bike |
| The RS4 125 is the younger sister of the RSV4, the superbike that has picked up the baton of the invincible war machines from Aprilia´s racing department that have dominated the 125cc and 250cc classes of the MotoGP. Today, as then, Aprilia continues to win on tracks all over the world, not with 2-stroke bikes but especially in the Superbike, the category that represents the highest expression of bikes derived from mass production. |
