I didn't get any speech (or vibe, even) from the Honda guys that you needed to specifically be ready to buy or anything like that to ride (maybe there was something in the T&Cs). I'd say you should have at least some ability to purchase (if you're declaring bankrupcy, maybe don't take a Panigale out for a spin), but I've tried a few bikes over the years that I didn't know if I'd like and I had changed my mind about them after the ride. I had tried a Bolt C-Spec a while back and considered buying one, but then I ended up having to move and buy a house, so it didn't work out. I'd say there is value in trying something outside of what you know you like, otherwise you'll never know if you like it.
I tried the CBR500R and Africa Twin at the Honda demo day. The CBR500R was a nice size and comfortable, but was fairly basic (no gear indicator, only very slightly more power than an R3). The bike also had a really nasty buzz ~5000rpm (sounded like a bunch of bees) and the bike generally vibrated a lot more than I would expect (more than, say, the 690 Duke). I tried it to recommend to the other half as an upgrade bike, but I don't think it would be much of a step up over the Ninja 300. The Africa Twin was pretty comfortable and the 270-Degree crank engine sounded nice, like a bigger FZ07. The bike was a bit down on power compared to others in its class though. I didn't get to test out the traction control system or off-road ability, obviously. I hadn't tried an adventure/touring-style bike before and was curious.
I retested the FZ10 since one of the guys said on here that the throttle did get fixed/adjusted after I mentioned it was weird, and it was 100x better. The thing really rips and has a great sound. It sounds a bit like a sewing machine when you rev it standing still, but it sounds pretty mean when you are able to get on it ; with an aftermarket pipe, even the calmest person would transform into a rev-happy hooligan. Going from riding that directly to getting back on my CBR1000RR felt really weird. The bike feels pretty "fat": wide bars, soft seat, wide tank. I can understand the appeal of the more relaxed riding position, heh. I'm still not sure how I feel about the Johnny 5 face though.
