I just looked up some demographics for the US motorcycle market and they have sold more bikes in the last 5 years than they ever did...they still worry about the aging biker ( 47yrs average) but they have been doing that for 20 years. If their data is including dirt bikes all bets are off, yes they are motorcycles but they are toys not a mode of transportation. They said a lot of their gains had been with young people and women, That suggests dirt bike to me.
My observation has been just like Lou's, what's out there are mostly Harleys, every once in a while an oil head or two, haven't seen a K bike in years. What happened to those 8 billion Gold Wings they sold, must be in someone's garage, not on the road for me to see. I have been 7000 miles plus this riding season across the Southwest into the South for my observations, No bikes.
The morning commute in Southern Calif. has lots of bikes maybe more than before. With cars making mileage close to what a bike gets(and more than a R80) you would seem that would push folks back to cars in the morning. Go figure
