I ve enjoyed having my own scooter a lot on the islands like koh lanta fe.
Atm I am in phuket and there the traffic is almost to much for me and I dont enjoy driving this much and most of the time i get a grab.
In BKK I would not even think about getting my own scooter ;-)
I used to love bike rides when i was living at home.But Phuket has a lot of steeply hills and bad drivers. Be careful and stay safe.!! :)
