Could anyone give me an advice on a direct tax office for paying my motorbike tax close to Ekamai/Thonglor. Talked to the 7/11 guys and they said it would take up to 2 months to complete the procedure. If I went to a real office it would be fixed on the same day. And I know I am out to fix this a bit to late hehe, but would really need to pay this in the few coming days. Thnx in advance!

How old is the bike? If over 5 years, you'll need an inspection. They can do it for you for about 100 baht.

well the Land transport office is at Bang Chak, near Sukhumwit 99.

As mentioned by Mickmick, the Land Transport Office at Bang Chak is the place to do this.

You will need your Insurance document (I believe)

You will need the Bike papers

You will need the emissions inspection cert if more than five years old (get that from the stations that show the yellow 'cog' sign on a blue background. 100 Baht or so.

Takes 10 mins to complete.

There is a drive through section on the left as you arrive at the main building. This is just for road tax, cars and bikes. No need to go the main Licence building.
