Hello Craig:
A couple of years ago I shipped my bike from Singapore to Darwin. Singapore was a nightmare. Without a carnet I had to truck my bike from the border with Malaysia to the shipping dock. They did not want the tires to touch S'pore. I think the shipping agent I used was VB Perkins or something like that. I seem to recall that there is only a couple of shipping lines going north to Singapore. Just do a google search. I personally would avoid S'pore like the plague. Boring place and sticklers for endless rules. Illegal to chew gum in public???????????? See if you can find a shipping line that will take you direct up to Port Klang in Malaysia. No carnet needed for either Malaysia or Thailand. I live in Chiang Mai along with David. Hope to see you up here. Great riding !!!! Cheers Robert
