don't post lies, all the time you post wrong things, nobody got denied or 60 days, the immigration officer at the border don't know anything about your reason of DTV, and if you would work illegal then you would be arrested at your work place.
why you act like you you know something? You know zero about Thai immigration. I am working in tourism since 13 years in Thailand and I know what officers can do and what not. I am minimum once a week at immigration dealing with them
If you have a motorbike from a rental company you have only the government insurance, this mean all property damage to your bike and 3rd party you have to pay if the accident was your fault.
