The design of the BMW Roof Box 520 is oriented to the car design of the manufacturer and has been optimised in regard to aerodynamics, volume and rigidity. Dynamic lines and harmonious proportions characterise the three-dimensional appearance. Side panels of contrasting colour generate visual lightness and give the box a flat and sporty appearance. It has a capacity of 520 litres and can accommodate a load of up to 70 kg. There is room for eight pairs of skis to fit in the box.
