The airline should have just charge 5 baht or waive off the excess weight or could suggest the excess 5kg go on the next flight .

Yes you can provided you converted to a Thai citizen.

Register a company and you can apply a work permit for her.

Just keep doing border bounce until you are being stop.

There is 150cc and 160cc.

Mostly in stock is 150cc as more people going for 150cc instead of 125cc. Most likely the dealer is not going to order 125cc for stock. Or another option is the Honda scoopy 110cc.

If you are only staying short term, why do want to have a Thai bank account? Paying an agent for an account to use on a short visit, will cost you at least 5000b or more for the account.

If you have the correct visa and residence certificate, just go to the bank no additional fees.

What visa are you having now? Tourist visa? If you have a non B or O visa, no additional charge to open an account.

If you are on tourist visa, they are selling you an insurance in order to process a bank account for you. If you really need a Thai bank account then just get the insurance that the bank provide. Bank will not scam your money as there is paper work involved in any money transaction.

Best and most accurate answer is from immigration. You can't get a correct answer from FB.
