The short version
Aprilia built the RS 457 like a shrunken RSV4: an aluminium twin-spar frame, the strongest engine the A2 rules allow and a proper electronics suite. It is the sharpest-handling small supersport and the twin revs out where the KTM single signs off.
Where it wins
- Aluminium frame is unique in the class
- 47.6 hp twin sits right on the A2 limit
- Ride modes, traction control and TFT standard
Where it loses
- Suspension is preload-only against the KTM's adjustable WP units
- Young dealer network for a bike that will need servicing
