I don't know enough about H-D to know what their alphabet soup of model names mean. But I know what a couple of them look like. At some point I need to figure out how I can convince my wife that a Eletrcaglide & Ultraglide scooters aren't "old men" bikes. She's the first one to complain about the rough ride on the C50 after 30 minutes...but doesn't want to upgrade to a scooter designed for two adults on a long ride.
