It depends on what you need:
Best for city travel: Activa, Dio, or Access 125 (easy parking, fuel-efficient).
For comfort: Royal Enfield Classic 350 (smooth ride).
For thrill: KTM Duke 390 or Yamaha R15.
For Delhi’s traffic conditions, a scooter or a commuter bike is a smart choice. If you plan to visit places like Agra or Jaipur, consider a Royal Enfield.
