I've not owned either but I have ridden the 1100 and 1300 Pan and although the 1300 is probably a better tourer, I thought the 1100 rode more like a proper bike, the 1300 handles well for such a heavy bike and is certainly very comfortable but it kind of felt like you're just being taken along for a ride. The 1100's suspension's less floaty and
comfortable but more communicative. The 1300 is much classier though, If I was in the market and could only have one bike I'd probably go for the 1100 cos it felt more like an all-rounder rather than a specified tourer but my mate had both a preferred the 1300.
