Aprilia RS 457 2026

The Aprilia RS 457 is an impressive bike in the A2 category, winning over riders with its harmonious combination of a powerful engine, sporty handling and attractive design. The engine delivers dynamic power, whilst the suspension offers a sporty and precise riding experience. The ergonomics and the sound also contribute to a positive overall impression. However, there are weaknesses in the brakes, particularly in terms of modulation and the behaviour of the ABS system when riding at the limits.
