Sorry for bringing up a several months-old thread, but I've got a similar question and figured it dovetailed nicely in here...
I'm 5'8", 150lbs, looking for my first bike. I go to school in Blacksburg, VA - so I've got some hilly terrain around me. There's a CB175 for sale locally that's in really nice shape, can easily afford it, problem is I don't think a 175 is going to quite cut it for the 300 mile round trip I'll be making every couple months or so, or whether it would instill a lot of confidence going up hilly roads into WV or on the Blue Ridge Parkway. Any 175 owners have a comment about that?
I'm also looking at a 550F, but that'll make me broke and does need some work to get it where I'd want it.
