    99 BDM Vintage Sport. Need info regarding frame tube diameter. Dad borrowed (read: f*&$ing lost!?) my calipers at the shop. Looking to fab up a highway bar to mount lights and pegs, need to know what size the frame tubes are so I can purchase clamp mounts for it.

    Any help would be greatly appreciated.

    take a piece of string, wrap it around tube, mark intersecting point with pen, measure that and divide by 3.1417.
