Well, yesterday was a day I never really looked forward too: I sold my 2002 CBR600F4i (aka The Mighty).

I had decided to sell the bike even before losing my job in March so it wasn't the end of the world for me but it still sucks to see your first bike (and one that is still so nice) go.
I only rode it TWICE last year on the track and not at all on the street because I've been commuting on my SM610. It just didn't make sense to have a bike sitting around when someone could...
