I went by the "local" (120 miles away) Aprilia dealer today.
they had a 4.5 Supermoto in the crate, but could order me a 5.5 if I want.
On another note, the new Tuono in grey/silver/black looks absolutely stunning.
Yes, it is. I'm at my friend's house so I'm posting under his name.
I'm waiting for AF1 Racing of New Braunfels, Texas, to do some more work on these supermotos and then I'll see what's going on. The new Tuono is a mighty fine machine but I kind of wanted to try the supermoto.
However, as of current, according to Aprilia's technical manual, these V-twins require boocoo maintenance by 5900-miles, but it's not known if they meant full-out racing or street conditions.
