Hi I took out compulsory insurance but am thinking its probably best to upgrade to first class insurance.

The bike is a 125 scooter worth 32000 baht. Does anybody know if this is possible and approximately how much it will cost?

Yes it is possible depending on the age of the bike - the cost for 1st Class is around the 7/8,000 Baht

You are talking about taking a big jump in coverage. 1st Class coverage is hard to get for your sized bike. But, you may be able to get it if your bike is fairly new. First Class will cover personal damage to your bike and it will cover theft. Most insurers are afraid to take the risk with your size bike because the premium would have to be too low for them to justify taking the risk.

Compulsory gives you a small amount 3rd Party Liability protection if you kill or injure someone with your bike, nothing more. Therefore, it might be wise for you to at least move up to Voluntary 3rd Party Liability protection. It expands your Compulsory liability protection considerably, including liabilty protection for property damage - plus more.

The compulsory will remain.......it's compulsory, no way to upgrade.

So, you will have to look for an insurance ON TOP OF the compulsory insurance.

As stated in previous post; won't be easy, but it depends on the age of the biked.

Usually it is more about personal damage and hospitallisation than damage on the bike.

You could try an accident-insurance at Lotus or any of the banks.

Please remind: Most travel-insurances do not cover accidents/damages to motorized means of transport (jet-ski, motor, car, etc.) Some even reject claims for hospitalisation after an accident.
