Potential owner with concerns with After Market Support

[Blitzrad_imp]

I really like the 2017 CB1100 EX and am currently doing comparison shopping with the Triumph Bonneville T120. The things that bring me to the Honda are the inline 4 engine and character it brings. The triumph brings a similar package but uses a lower revving twin, but it comes with heated grips and has an option for cruise control. Both have a good sound coming out of the box and Motorcycle.com with their review has them pretty much neck and neck.

My concern has been the after market support for the 2017 CB 1100 model as it has been difficult to find the items i want to add to it. With these questions I have started to lean towards the Bonneville and am hoping this forum can help me out. Below are the additions i want to add. One of my questions is do the accessories from the 2014 model fit on the 2017? Your help is appreciated.

--Heated Grips - Plan on going Honda
--12 Volt Adaptor put on handlebar - Hook up to battery or is there a socket to use?
--Chrome Rear Carrier - Honda website does not have one, does 2014 fit? Online not showing options for 2017.
