The front headlamps of most modern vehicles are exposed to significantly higher loads than in the past. Plastic windows and permanently high temperatures quickly cause the glass to become cloudy. The result is poor visibility at night or even failing the TÜV. Furthermore, the brackets in the front fairing of the YZF break out quickly even in the event of a minor accident. A correct adjustment of the headlight is then no longer possible and the TÜV can also refuse to issue the sticker.
