I do this often, I'll drop the passenger pegs hook my ankles on there lay ont he tank and cruise for a little while when i need to stretch out on a long haul. if anything went wrong i'd probably be in a tough spot but I practice bringing my feet back to rider pegs just in case i have an emergency situation.Lol. To be honest, sometimes I think a bike where you can just rest your chest on the gas tank would be more comfortable than riding in the upright position on my Buell at 70 mph. At least laying over your not getting totally brutalized by the wind.
You can lay forward or sit upward on a Buell. Some people are just misinformed OR jealous.I've ridden over 900. miles in a day but Dang I was somewhat tired.I think some of us have used the back pegs to keep riding to a Destination many a time. Being a Former Marine I like the wind rushing around me.But I liked it as a youngun also.Grew up riding Horses pretty much every day.Liked the wind then too and the wildness about it.Most NOT all,seem to get the Foreign bikes for Straight line Speed.Put a good handling bike under me anyday.:D
