The RS4 50 Replica was a paint-only edition of the standard RS4 50, dressing the 50 cc two-stroke in a copy of the factory RSV4 Superbike race livery. It came in red with Italian-flag accents on the front flanks and Eni and Dell'Orto sponsor decals, while frame, engine, brakes and suspension were carried over unchanged. It gave young riders the look of Aprilia's world championship bike without any mechanical differences.
