I agree on the bell, mine was the best thing I added to my bike. If you go to a quality bicycle shop, they may have a nice size chrome one like I got. People look twice before they realize what it is(when the bike is sitting still and the crowds are looking at it instead of the Harleys) When you ring it, everybody smiles. Luckily, around here, nobody else has one, get yours BEFORE your Harley friends, and they can follow your lead!
