The bike as photographed weighs 3.8kg(8.36lbs). That weight is for the full build excluding pedals.
To put that into perspectve a light bike these days would be anything under 6kg. Anything between 4.5kg to 5.5kg is super light, this bike is 3.8kg! Amazing since it was it built in the 70s! The decals are not original in the color pictures. The black and white pictures show the bike as it appeared in the 70's
