Of all the accessories that either came on your F6b or that you installed, which has exceeded your expectations the most.
For me, it'd have to be the heated grips. Since I bought a standard leftover 2013 new, it didn't come with them but I had the opportunity to buy a used set. WOW, do they ever get warm and put out some serious heat. I love the idea that they have multiple settings. I like them far better than I thought I would. I wouldn't want to live without them this time of year up by Chicago.
Just curious what the other members think.
