actual temptation that we could possibly afford... RC51, 6th gen VFR, used RSV4, or 04 R1.
I just accidentally acquired an Rc51 myself. Full on track bike, but whee! I love me some V-twin sport bike.
I'm pre-tempted by the 1290 GT, after riding the 1290 SD. I also shop shop shop for used bikes, but with no intent to buy; the RC was pretty much too good to walk away from!
