Why dont Millennials buy motorcycles?

That mini enduro 60 was a 71 or a 72. We rocked that up until about 1985, then my friend who owned it finally retired it just a few years ago when he tried to start it up after decades of storage and something broke with no spares available. a 95% restored one sold at auction @ Mecum in Vegas 2016.
