I called the guy that did my frame and he said it was 6-8 pounds for just the frame (mine is the extended track frame) with an Illusion color. I think they ordered 10 pounds for mine and he still had quite a bit left over even with all the other parts they did on mine beyond the frame (subframe, windshield bracket, kick plate, motor mounts, rod ends, valve cover, battery bracket, 2 reservoir brackets, & toe link bar).
Mine was Prismatic Powder's Illusion Purple. He said with a standard color it would have been less powder because they typically cover better than the fancy finishes so they don't need as much powder.
