I agree with Rex. I had so many issues with stability on uneven surfaces on my sv 650s that were resolved when it finally fit me right. (lowering links & scooped seat)
I had to start over when I got the sv 1000s. Unfortunately, the timing was such that by the time I picked up that scoot and got it into the shop before my first long-distance trip the only lowering that was done to it was the lowering link in the back. As a result, I had some scary touch and go moments for the first 2 legs of my long haul. I wasn't used to the additional weight the 1000s had over my 650s and with it fully loaded for the trip it was a struggle for me. I had to go out of my way to find flat surfaces, or ask a friend to help pull me to a center point where both my feet were down (toes/balls of feet - not flat foot) .
I had a really frustrating moment by myself behind a hotel in NJ that had a slight slant to the parking lot with no one around to help me. Thanks to determination and a cement block in a nearby parking spot I managed to continue my journey. I walked my bike right up along side that cement block, stepped up on it, got myself into position with one leg over and pushed off the block to get my bike off the stand with me on it. (For a moment I sat there thinking now what? What happens when I get to the next traffic light and there is a slant in the road? Am I going to go down? but then I said "Hell with it! The only way to know is to just go"... and if it happens I'll deal with it then)
Not having my feet firmly planted while on that bike took up some major mental real estate. After I left that hotel in NJ I needed gas on the turnpike I had to scan the attendants before committing to a gas line to see which one looked most likely to help give me a push (or pull) to get the bike off it's stand after I filled up. Luckily the ground was flat and I could do it without having to embarrass myself and ask for help in that way. You really need both your feet solidly on the ground to do this. The only thing I cared about that day was getting to VA, I promised a friend I'd be there that night so I kept going.
Another issue you may find with short legs? Bruised calves. By the time I got to VA the calves on both my legs were so deeply bruised it felt like charlie horses. When you are on tippy-toes at stops your calves are tight, Depending on the type of bike, if the foot pegs are placed so that they bump your tightened muscles you'll bruise. Do that repetitively and the bruising goes deeper and spreads. It's painful. I wore leather boots but they ended just below the muscle of my calves, which was right below where the pegs hit every time I stopped.
When I got to VA I refused to go any further until I had the 1000s lowered more (the forks pulled and the seat scooped) so I took it to a shop I found online. When I showed the guy at the counter my bruised calves he told me about some fully adjustable foot pegs that rotate to any position 360 degrees as well as shifting forward or back depending on length of your foot. So, if you have short legs like me, it isn't just the flat foot issue, it's the wide stance you lack. Again, depending on the type of bike you ride, the pegs will get you unless you can move them either forward or backward away from where your legs are positioned when your feet are down.
Let me tell you all of that work was worth every cent AND the delay to my road trip. It made a huge difference in both comfort and safety for the remainder of my ride. I could focus more on enjoying it and less on how to avoid dropping the bike on a slanted surface, or how much my calves were hurting.
I know you have a lot to deliberate over, and perhaps the knowledge we are imparting is not directly applicable to your specific situation, but maybe it will help down the road once you get the bike part resolved... or maybe it will help others reading this forum.
Whatever direction you choose I wish you the best of luck!
& may you never have to suffer this:
