Well, I have ordered the risers, cup holders, bluetooth to aux transmitter, and a LED H4 headlamp bulb. Installed the riders backrest today that came with it but wasn't on it. I think that's about all I need for now. I don't plan on going crazy with upgrades on this one,. I know you have all heard that before though. Fact is, most accessories for the RSV are no longer in production and are too expensive if you finally find something. Only thing I would kind of like to add is the rear fender tips but they seem to be rare also. I'm happy with it as is.
