You have to place best selling in some kind of context. BMW has about 1.2% of the US market and struggles to sell bikes in the tens of thousands over here. 1.3 tens of thousands to be exact for the last year they released figures. So a bike that sells a few thousand a year for them isn't that big of a seller if it does not sell in the UK and EC markets which the Chromeheads did not.
