        It’s a very good entry-level sportbike. Very comfortable to ride, with good handling. It’s easy to control, and the braking is impressive. Overall, easy to manage and fun to ride.

        All-around great bike with no problems. Mileage is 25–30 km/l, looks and color are perfect, and it can go up to 206 km. A true road king.

        The engine is solid and performs well. The looks are decent, though the paint job could use some improvement. The display occasionally blinks, but overall quality is acceptable coming from Piaggio. It’s an incredibly affordable 457cc bike. While Kawasaki might be more popular, it's rare to see another Aprilia around town — which makes it feel unique.
