Tried KJM - that pic on their website is an old one; they currently have no stock.
Its looking like I'll have to do a personal import if I get a new one. Probably from the US.
Why a new one? Yes, I know they are dogs new, but this is easy to fix. Also, with a new bike I know what I'm starting with.
The more I think about though, the less I want to import a bike myself. I might go for an XR650R instead. Originally I was not keen on the R's ally frame (short critical crack length, harder to repair than steel). However, the trip I'm planning is not that mad (TransAmerica trial), there are plenty of Honda shops on the way, and I'm planning to go ultra-light - so might not load the subframe too much.
