Benelli,
Sorry to hear about your friend.
Hope he pulls through.
You're right, a 800 pound bike is more like a weapon than a big toy.
it can hurt ya bad and starting smaller I would think,
is the BEST way to familiarize yourself with riding.
But some choose to start big and that's their choice.
I started out on a honda 100 back about 73.
Wife started out on a harley dyna about 3 or 4 years ago.
She's had 1 close call, I've had hundreds,
so it's hard to say which way is better.
Time, and expierence in the saddle, or luck,
with God's grace and mercy.
I'll say a prayer for your friend.
