I would just hate to pay any kind of shipping from over there. It's a ton of money and you are screwed if it's not up your standards when you get it. I would keep looking for some wheels in the U.S. I would track down the part number for the rims and start calling around trying to locate some. There are some out there in someone's inventory somewhere. Either that or some will pop up on Ebay. They should be the exact same as my Honda 160 as well. So there are a few bikes that will be sharing that part number.
Also give
Charlie's Place a call for some Honda wheel advice. If anyone can help you quickly they should know where to find some since fixing old Honda motorcycles is what they do. They have some cool stuff on that site. I still haven't had time to go through it all.
