AFAIK the CBR300R is being manufactured in Thailand.

When I was in Northern Thailand this past Jan & Feb, I spent several days riding in a small group and one of the riders had a CBR250R which he liked a lot. The CBR250R owner/rider, Doug, is a fairly short guy so there weren't a lot of choices as far as potential motorcycle purchase went for him at the time (I seem to recall he'd owned the bike just over a year or thereabouts). He could ride that lil CBR250 quite well, though he was surprised that a couple of us on DS type bikes could keep up with him, or on some rides, he was unable to stay with us on some of the great mountain runs we did over by Nan.


Doug was fairly enthusiastic about buying a replacement bike and was seriously considering the Honda CBR300R as he likes the 250R that much (I'm almost certain Doug said the CBR300R is being made in Thailand - but I was drunk on riding at the time - so I could be mistaken).
FWIW I'm not sure that there's that much of a significant difference in my mind to make the trade, but one might say that 'us' motorcyclists throw all objectivity 'out the window' when it comes to motorcycles...
