You did not specify where you come from, but if you have a valid motorcycle license from a European country or the US, Australia or any other Western country you probably only need to do a few tests.... and most foreigners describe it as very easy...
If you not have a drivers license, you can get it in Thailand. Most Thai people apply for a motorcycle license at a very young age, but the best thing to do is to rent a 125cc scooter and do your drivers test on that... After you receive your license you can directly ride anything with two wheels regardless of engine size or horsepower...

I have a new Zealand licence and was required only to show proof of residency, pass a eye test and also a co-ordination test. There was no written or practical exam.
One benefit of owning a Thai licence is that you won't be discriminated against at such places as National Parks etc.
You will be required to pay only what Thais pay to enter.
So the licence soon 'pays for itself'!!
Oh, and showing a Thai licence to the ''Boys in Brown seems to impress them!
