Why does it matter he's 17? you make it sound like a big deal.
if experience is there...any age can do anything.
if he hasn't ever had experience with at least a car assuming not with bikes...then that is on you. MSF offers bikes for use in a safe environment to teach in so dropping isn't an issue...
you don't seem too fond of your son stating out on a forum
"17 year old son crashed bike"
