You will not see them except for Australia. Honda was exporting CB400 to Australia as a entry model.
HONDA has been selling many CB400 super four to Japanese market.
So many used CB400 is found,we can get used CB400 super four with reasonable price.
I am very interested in this model as a cafe racer base.
Above two photos are CB400SF is not cafe racer,but it is cool! I like it!
