The 75-76 GL1000 (Goldwing) wheels came with aluminum DID rims. They look quite a bit different than the stock steel rims on Hondas; the aluminum rims are dull matte while the steel are shiny chromed, and the sides of the aluminum rims are wide and flat, as opposed to the narrow, gently radiused steel rims.
And my personal way to judge the difference between alloy bits and steel bits on a thirty year old bike? If it's not rusty, it ain't steel!
