I am curious about the st1300. i have done the similar route to the dragon a few times ,the snake once on my 05 fz1 from boston few times. the 500 miles on a fz1 are killer being 6 3,250
alot of places to ride down there for sure. i typically do 3k in 7 days and that is hectic as hell.
the rt16 ride4321 speaks is too tight even for a fz1. it will be a blast on a smaller or lighter bike. i got worn down after 4 hrs on that.
