The stuff that has been added so far:
D&D pipes with K&N drop in and flashed at the dealer.
Some nice Chrome pull back risers.
Solo Seat with backrest, Touring seat with backrest.
Highway bars
I think that's it.
I plan on doing some stuff after I get used to it. Not sure if I want to do triple K&N and remove the secondaries or GiPro ATRE. There's plenty folks are doing to these bikes. I'm still learning and reading as much as I can on their sites.
