Just a few upgrades.... so far. Passanger running boadrs, engine guard, highway pegs, sport luggage rack, light visors, HD removable luggage bag, battery tender harness.... and i'm sure the add-on's will continue... just don't tell my wife:14:. Not really an add on... but I picked up a nail in my back tire last week and had to replace the tire ($270 bill).... But i still love this thing! Today it's back at the dealer... I hit 1000 miles already!
