I do remember the hub bolt on the Honda's quite torquey, I think it was something like 254 lbs, I have to check though. What I did is, I had an assistant step on the brakes, while I used a breaker bar to bust that sucker loose. Then again, I am a fairly strong guy (not like body builders or anything), but I did put a lot of effort into it though as I remember. I heard a story about someone stomping on a breaker bar to bust it loose, and somehow he missed, and the breaker bar flipped off the socket, and hit him right in the "danger zone". :chuckles: Needless to say, it was a one-hit knockout for him, and it took him a bit to recover.
You could always soak the bolt in penetrating oil overnight and try again. Some use simple WD-40 also instead of penetrating oil.
