The starting point is a SIL air filter box. A connection piece to the frame with a diameter of 50 mm is hard-soldered into this. This means that the diameter of the air box corresponds to that of the frame. The box and the air filter connection piece are powder-coated white. All additional work was carried out on site in Cologne.
The scope of delivery includes:
Modified and powder-coated air filter box
bgm PRO air filter
Powder-coated air filter socket
Clamp, seal, plate, screw and stop nut (different from the wing nut shown).
The idea behind the box is to realize an original look with a reasonable air filter solution. The sound is more pleasant than with a completely open carburetor or one of the solutions with a foam filter. In terms of performance, we were unable to detect any losses with an engine with an output of around 20 hp at the wheel. The box is a direct and complete replacement for your original air filter box.
