Weighing in at 220 kg (485 pounds) with fluids, the A 65 strikes a balance between a sturdy build and agility, allowing for confident cornering and maneuverability. The 15-litre fuel tank ensures that riders can enjoy extended journeys without frequent stops, making it an ideal choice for both leisurely rides and spirited outings. **
