Seen a few of EC VMX bikes that have arrived here & none of the buyers were happy. Bikes look & sound good in the adds, but there's generally no full disclosure, things like painted plastics (including plastic fuel tanks)& plenty of rust. Once again, ask the hard questions before you buy, but IMO it would have to be something rare that you really wanted to have to even consider any bike from USA (not just theirs) with the exchange rate where it is. There are plenty of bikes here in Oz to buy.
