Windshield
Having a long torso, I haven't found one that really does the job well. I can raise the OEM to near the right height but then I get a bunch of air coming up from under it and over the tank !
I know install lowers......... Dam those things look cheesy.
Other than that I wouldn't buy a bike that required changing more than a $100 worth of stuff on, if you have to mod it out that much then you didn't choose the right bike.
Oh yeah ! I know, everybody wants to personalize it by putting all the same add-ons as everybody else ???????? I have about the most singular Volusia I've seen, because it's stock !!!!!!!!
