My inseam is about 30 or so, and I’m 1.5m (about 5’5″). The 250/500 are 30.5″. I have some slight problems, but not too terribly much in that the twins are squished and crying.
Guess it depends on what I wear pant wise too, if I can fit properly.
Initially, my thinking is that my 500 is too much for me to begin with, especially with the crazy drivers here in the city (Chicago). Thus I’ve been second guessing myself at times. But in the end, I ended up getting the 500. In the short term, it’s a bit rash, but looking at it in the long term it will be fine for what I plan to do (tour about with it, long commutes).
I do not think you’ll look too odd on the bike really. There was an article in a UK mag (“Performance Bike”) recently, with a tall bloke on the 250R and he enjoyed it. Didn’t look odd to me, when I saw the pics.
