    I was looking at 3/16 steel for rigidity but running the weight on it, it would be about 5 lbs. the oem rack is heavy as hell as well.

    Is there much flexing in the rack with it being aluminum?

    There is a ton of flexing with the MP3. My cracked just past the welds after I mounted a razor tourpak to it. Had to make my own mounting plate assembly including aluminum risers that bolt to the F6B frame, and I used a 1/2" aluminum plate. All flexing is gone now. I have no idea how to post pictures on this website. It's beyond my computer expertise.

    That's what I was afraid of. Will probably end up going with steel but at a cost of increase in weight. Or I can weld ribs under it to eliminate flexing.

    Regardless, I don't think I will be able to tell a difference in 3.5 lbs vs 5 lbs once installed.

    Here's a website that has some of my pictures. You won't notice the weight increase with steel. Ribs underneath is a great idea. Hope this helps.

    Av8er,
    The aluminium is 3/16".
    The bracketed area is two more 3/16" pieces then all 3 welded together.

    I had a large bag on mine (see the pic of "Me chasing a darksider" in the Darkside sub-forum) for several trips and never had a cracking issue.
    Yes it was clothing and I kept it to less than 20 lbs back there or I'd feel the rear end want to do its own thing.

    Happy building!
    Steve

    This is the rack - loaded.
    The "T-Bag" is actually on the rear seat.
