text: 4.how can harley davidson sustain and enhance its competitive position?   harley davidson's success is due to their product having an appealling image.  there maybe some domestic growth potential in increasing motorcycle riding.  however their true potential for growth is international.    china could potentially be a gold mine for them.  it is a huge, growing, modernizing economy with high population density that makes motorcycles very attractive.  i think they will need to adapt their product and marketing to appeal to foreign markets.
