Somewhat. The older guys can afford the expensive ones while the younger guys are still raising families. Things are changing though. Millennials want to spend their free time in front of a screen with an X-Box playing virtual games rather that getting out there in the wind and feel the freedom only a motorcycle can give.
Maybe when electric bikes are both affordable and common; that will start to change. Electric bikes will require almost no maintenance; just tire changes and drive belt adjustments once in a great while.
There are still plenty of young road racers out there. Some of them are quick as hell and know how to get thru a turn. None of them are sitting on Harleys though.
