Vrod - Newbie help with what type of metal each part is

I am new to the Harley scene and would like some help identifying what the parts of my 2003 Harley are made of. I have read some posts on the forum where people though something was chrome and it was not or thought the aluminium parts are chrome and they were not.

Here is a list of the parts that I don't know the material. I would be grateful if you could let me know which parts are chrome, steel, brushed aluminium etc... I will update the list as I get replies and once it is complete I will make a image guide (sample at bottom of post), I really think it will be helpful to new people on the scene.
