I think the Japanese are probably searching for a model to catch on in Europe thus the increased variety of options. 80%->50% is a big drop. In the U.S. as you have said in they are good shape thus no desperate moves. If you research the number of new models vs. all motorcycles sold I would suspect you would find a very similar ratio as the auto industry. I don't think H-D tactics necessarily transfer to the Japanese makers as they produce more that just one (cruiser) type, ignoring Buell.
