The way i see it, American bikes = long distance cruising and comfort. Japanese = short and zippy and a pain to ride distance. I allways wanted a crotch rocket for the speed and shit, but if I ever got one it would prolly be a harley or similar. They're just made for driving for days on end. Plus, there's really no need to go 0-60 in a blink of an eye. That is unless you live in the matrix or something. Both really good bikes, but really different.
