As others have said, my advice is to proceed with caution, if you are thinking of joining the K16 set. These are big old buses, heavy bikes & ownership can get expensive - just try trading one.
OK, I'm a bit biased, as my 2012 K16GT SE was an absolute lemon. Everything that could go wrong did - I won't bore you with the detail, suffice it to say, after 3 months in the shop waiting for parts, it had to go. Anyway, have a good browse through the forum ....... www.k1600forum.com .... if you haven't done so already Later builds, say post 2015, appear far better &, of course, the almost inperceptable facelift in 2017 brought a few more bells & whistles.
Yes, that big 6 is creamy smooth & seductive, but I'm with JJH here - an FJR won't be far behind, is super reliable, very reasonable to run &, that bit smaller/lighter - maybe a bit 'anonymous' though, if that matters. Then there are the likes of the H2SX, which takes the idea of a sports tourer on a step........or two.
Personally, I tend to think the days of the big tourer are almost over. Riders are looking for more versatility, hence the rise & rise of the adventure sector, just as we have seen in the car market with SUVs. Hardly surprising then to find that we still have the big GS dominating sales charts in the UK, just a shame the new baby brother isn't more impressive.
BTW, Just my 2p worth. Have fun deciding.
He's right with that summary........... a K16 wouldn't float my boat
