Joe,from what you said,the 750 has more "potential" as far as what it can do for you..ie,going to Wisconsin or any other road trip,the 450 seems to be more limited in what it can do for you.
I agree 150%, thus my dilemma.
After riding the CB450 last night I am even more at a loss to make a decision.
I am more "into" the CB450 now because I like how it has turned out, and I still have a boatload of other things I want to do/add to it to make it ever more killer than it is now (different tank/dual discs/etc...)
I am sure it could do a tollway trek if need be, but I still have to get some more seat time in it before I feel comfortable enough to venture onto the highway with it. The more I rode it last night the more I was surprised as to just how streetable it is, with being as low as it is...
This coming Saturday me and the rest of the Ton-Up Chicago guys are having a bar-b-q with the windy city rollers (roller derby tattooed girls in fishnets

), and I am gonna ride the CB450 to put some more miles on it. I think the more the CB450 proves itself as a reliable runner the more I am gonna lean to keeping it..
Not to get into my personal affairs but I kinda built up more than alittle credit card debt, and I would use the money i would get for one of these bikes and put it towards that. I know it wouldn't be much, but anything is better than nothing... Like I said I am doing everything I can to keep both bikes till atleast the winter hits, then I can figure out more of what I wanna do...
