I can only speak to my area, and immediate group of friends (ages 45-55). Most of us have ridden, or still ride dirt bikes. A few have HD's, one an Indian (nifty bike), and quite a few have the "adventure" bikes. I see a LOT of bmw's on the roads these days. And even a fair spattering of Triumphs. That said, the younger crowd (less than 30) "seem" to be more on crotch rockets, or scooters. Not much in between, and rarely ever on a cruiser type bike.
And for what it is worth. I spend my time on a triumph speed triple.
