...has anyone jumped their Versys?
I've gotten a little air a couple of times going over steeply sloped railroad grades...just a little, though.
There's an ADV member named Sanjoh who has modified a 650r with a USD KTM front end, and he has jumped that bike. Do a little looking on that site and you will find it.
You can get little bits of air on the V, as I previously mentioned, without getting close to bottoming the front forks/rear end; but, I wouldn't make a habit of it as the combo of relatively short travel and high spring rates (especially in the rear!) could result in damage - to you and/or the bike.
BTW, I've only managed to bottom the front end four times, and I was actually trying to do it, when I actually managed to do it. Though, worth mentioning, I also had an extra 100 lbs of gear on the bike.
You could definitely take it on single track, with Anakees or TKCs, etc.; but, if I'm gonna ride single track, I would rather be on a mountain bike than a motorbike; and, at 400+ lbs, the V is more than I would care to pick up on a regular basis.
If "jumping curbs" is what you are looking to do, the 130/80/17 front tires work great for riding over curbs, or deep/steep potholes - without bending the front wheel - even with an extra 100 lbs of gear onboard.
My best advice: do WTF you want with your bike and don't listen to other folks opinions, unless (caveat) they've actually done
the mods and/or activities you are interested in. There are soo many choices for bikes/parts/crap out there, that too many folks engage in talking/worrying about what they need to do something; vice, just doing it. I don't mean to sound like a Nike commercial, but it's a simple fact, based upon observations during my two year stint (thus far) as a motorbiker.
I've included a pic of my bike as it seems to somewhat mirror your ideal of a ADV commuter bike, based upon the mods you mentioned. It's also endured a 12.5k mile cross continent trip, but it had a few more things on it for that.
