At the Kawasaki event I went to last week where you can have a long ride of a brand spanking new bike for free I was easily the youngest person there bar the girls in tight tshirts (they had a BBQ and loud music to make it feel like a party). The models on offer show this, it's all middleweight touring, classic styled, commuting type bikes. They had one ZX-10R in the whole show room, although quite a few Z H2s. I don't think bikes are really all that interesting to most people, you either want one or you don't, whereas most people recognise a fast car or whatever.
