Since you have had such a lovely experience with your Dazzler, you could play it safe and replace it with the Honda Unicorn / SP160 - both of which can trace their roots back to your machine. Other options for you in a similar displacement bracket are the TVS Apache RTR 160 4V and Bajaj Pulsar N160. 

Coming to scooters, we would recommend the TVS Ntorq 125 or Ntorq150 - depending on your budget - both of which are sporty, capable and comfortable scooters that will stand out from the crowd. The only reason we would steer you away from the Yamaha Aerox is its stiff rear suspension, which will get tiring and downright intolerable if you stay in an area with less-than-perfect roads.
