I ride 2-up on my 400 all the time, but only on longer trips of 400 miles one way, (long for me) i do wish for a little more, and that's only 20 mile stretches of interstate I take at 75-80 mph. It seems to be pretty wrung out at that speed and I don't want to ruin it. The alternate way I have in this same trip is ALL interstate speeds which I'm afraid to try for that long, even though we stop about every 100 miles for a short break.
(My 400 is all stock as far as clutching)
