Thanks for all the feedback and discussion. The savings in gas was just one way of looking at it. I really do enjoy riding bikes and always have. Started with a Honda Trail 70 about 20 years ago or so and still have it.
I was riding my brother's 1978 Honda 400 something street bike for a while, but not commuting, just the fun back roads kind of ride. He has since traded it for a 4-wheeler, which is tons of fun too! So I was really looking for advice on what type of bike would be big enough for power and stability on a major highway, yet decent fuel consumption and light enough for me to handle.
I already own two cars and am not interested in another car, I want a motorcycle!
I looked at the dual sports and they seem great, but just too tall for me. I don't feel safe when I stop on them. I like to place both feet on the ground flat footed, not tippy toes. I love the idea of the VStrom , but the same problem it just seemed too tall and a little big, plus the price was a little more than I wanted to pay. I have never actually rode one though. No place around here rents bikes and the dealer that has them says insurance won't let people test drive the bikes.
There are some back roads that I could use to take to work each day, but it would be more miles and take longer each day, so probably not worth it from a financial perspective, but would be fun!
So it comes down to the question of what am I going to use this bike for and how much. I know I would take it for fun rides periodically, but was hoping commuting would be included in that, but from what it sounds like commuting is not fun.
I am going to look at a 95 Honda VLX 600 on friday for $2300 with about 7k miles.
