hey man i couldnt honestly tell u, but i know a guy from work with a similar frame with the fast ace as-02s from dhz. yours looks a bit like mine where the tubes go through the frame for the engine mounts. mine were only just tacked on there for causing the frame to crack like a b**ch, somthing to watch! the new dhz's are better you can see where they have been strengthend the its a bit hard to tell by the pic plus im pissed. if its a crf50/xr 50 copy the fast ace should fit only thing to watch may be the actual size of the forks(length) anyone correct me if i am wrong! i dont know what they would be like on yours though mabye some one could shed some more light on your situation man.
