Where to get Suzuki spares?

I looked through all the relevant forums. Apologies if it has been posted before.

I need a few parts for my DR650SE, clutch plates and oil filter. Can I buy or order them somewhere in Thailand, or do I have to import them myself?

One of the local shops here said they could get them, but want to send the old ones to Bkk so they can be matched up. Bike out of action for a week, plus I'll have to work on it twice. There must be an easier way.
