Rated 5 out of 5 stars
Sehr guter Helm für alle die gerne mit Jet-Helm fahren.
Für mich prima Passform, windstabil, und sieht auch noch gut aus. Ich fahre damit auf dem Motorrad auch schonmal schneller, was sehr gut funktioniert. Ich kann den Helm auf jeden Fall empfehlen.

Kann ich nur empfehlen, sehr gute Fahrgeräusche. Hoher Tragekomfort. Alles im Allem sein Geld wert. Würde ich noch einmal kaufen
