We got our done for $135, and thats including the sandblasting it as well. Of course he is sponsoring my son's racing, and he gave us a better price, but his normal price would be about $200 for frame, and swingarm.
As for the rest we are doing it ourselves, and will only cost us powder. Starting in the spring we will be doing our own frames as well, but we have to finish our oven build 1st.
