Meet Mario Kümpel also known as Surferzyzz who is now riding on the best race foil on the planet. The F4 race bundle! See the interview we did with Mario sharing his stories about F4 and joining the team. Mario is normally doing his videos in German but today we got him to speak English for a change. Happy to have you riding on F4 foils, Mario, and thanks for the nice chat! Check out his youtube channel and look out for more vlogs about F4
