#1 = 2010 CB1100. Hands down.
#2 = Triumph Thunderbird Sport. It's a shame they quite making them.
#3 = Aprilia Shiver 750. I know, it's not a classic. I just love it.
#4 = Harley Nightster. Don't kill me. I have loathed them (HD) since my brother drove one home in 1976, but there is something about that silver and black nightster that speaks to me
#5 = Ryca CS-1. Google it! Thumper, thumper, thumper. But for $9k, see any of the above.
