Specifically, what are the differences between the Sport (not T-Sport) and Custom model Super Glides?

Are there suspension differences or just cosmetic differences?

Tried the search option, but not coming up with much.

 

What years are you looking at?

Super Glide Custom has more chrome, spoke wheels, and the speedometer on the tank relative to a base Super Glide. Still in production

Super Glide Sport is more blacked out, has taller suspension, gauges on the bars, and dual front disks. I think they quit making them around '03. I'm sure someone with more knowledge of that model will chime in.
