I'm so sorry to hear about your accident and injuries! I can relate to your feelings, for I managed to pin myself under a student bike while taking the MSF Basic Rider Course, and I spent an entire night in the ER, getting X-rays, MRIs and sonograms. I didn't hurt nearly as much as I'm certain you do (from the description of your injuries), but my right leg still looks weird after more than a year, a daily reminder of the mishap. And this was before I even got my license endorsed for motorcycles, and I had not even begun looking for a bike to purchase! (I had ridden scooters and lightweight cycles in high school and college, but had not ridden for several decades until last year.)

Hmmm. You didn't mention in your previous postings that your R65 was too tall for you, so I wonder if you would find a 250 to be, otherwise, that much more manageable than an R65. I was considering a 250 when I took the MSF course. Personally, I didn't find the 250 I rode during the course as manageable as my R65. The 250 wasn't that much lighter than my present bike, it wasn't that much slower, it wasn't as stable (IMHO), and it *certainly* wasn't as much fun. First things first: don't fret over this while you're recovering. Decide that you want to ride again, then take your time deciding what to buy.
I wish you a quick recovery.
Best wishes,
John
