I don't know the exact rpm at 85, maybe 6k... it doesn't sound like it's straining at all. It'll still pull up to 100 easy just by rolling on the throttle, it's right at it's peak power output cruising above highway speeds in 6th gear.
I have a hard time believing a Versys will hang with the 1050 until 110....my FZ1 pulled INSANELY hard and would have walked away from the V above 50-70mph, even if the V can keep up at 110, if they're both accelerating at full throttle I'd think the big bike would be pulling ahead fast once past 60mph or so. Not that it really matters.
I was following a buddy on the highway, he was on a 900RR that my FZ1 used to smoke, and he was pulling away hard on the beltway when he opened it up, but I was able to keep up (within a couple hundred yards) because there's only so fast you can go, just don't expect to keep up with a WOT liter bike on the V.
Back on topic, bigger motor = more weight. Yeah, you can go a lot faster and get there quicker, but the bike will be heavier. The light weight of the V is part of what makes it so much fun and quick handling. Sure, an R1 might not weight too much more, but you're not going to be anywhere near as comfortable as you would on the Versys. Not even close!
I've got no idea about cruisers.....
