Congrats on the new bike and best of luck with three major upgrades :-) This is a big bike and has lots and lots of room for farkles....
Lot of useful information around about these bikes now so it should be fairly easy to outfit a new C-14.
Quite a few choices on saddle and saddle / cushion combos; mine is a Corbin wearing an Airhawk but it would depend on how long you need to sit on the bike- the Airhawk alone might work well enough on the stock saddle if you are not spending a long time on the bike.
As far as cruise controls go, you really only have two choices: the Rostra, which is about $200 - $250 but takes some light fabricating and hand- wiring, or the McCruise which is either Plug 'n Play or extremely close (some units require a spliced wire or two but no mechanical work beyond installation) and was around $1,100 last time I looked. Then there are about a gazillion varieties of throttle locks ranging from a $1 rubber band to some pretty sophisticated mechanical contraptions. But do bear in mind that none of this last group is a true, speed regulating, cruise control.

Just bought a brand new 2015 Connie (Kawi green) on the 30th october. already put 1400 miles on her and she is a great bike. Those battle axe tires really are crap though. What do you guys suggest? anyway I named the bike "HULKETTE". The 1000 mile ride I took on her taught me that I need 3 major upgrades. 1.Those tires are crap! 2.After 100 miles that seat is like riding on a piece of lumber. 3. Cruise control (or throttlemeister).
