    I'll try to get measurements for you by the weekend. You want the diameter for the subframe correct?

    Be aware that tube OD's vary, depending on where, exactly on the bike you are measuring. All of the above measurements are for the down tube that originates from the steering headpipe, and mounts the front and rear of the engine.
