Ok, in 2008 HD was some 300,000 units, Honda was an astounding TEN MILLION! Lots of room for Triumph to grow.
To be honest though the bulk of hondas sales are in asia and probably very small machines. The average $ value is about 10% of the north american average.
Both honda and hd will be well off their north american numbers in 2009.
