Don’t discount the Ninja 250 as a first bike. They are probably the easiest bikes to find on the used market and are not hard to resell. If you buy used you won’t loose much if you decide to upgrade. The Ninja seems to be the balance between easy to learn size and capability. On the Ninja 250 forums someone just posted their ride report of over 4000 miles in 5 days on a Iron Butt with moving averages near 70 and top speeds near 90.
Still I do like the Versys and Weestrom. They are both at the top of my list for a second bike. I think for a beginner bike they would work but only for a very tall and strong rider as the tall top heavy nature of the bikes will not forgive rookie mistakes at low speeds easily.
