A group of adventurous bikers from Chicago spent three weeks this spring touring Vietnam by motorcycle reports Business Insider, a leading US business and entertainment website.

Dubbing their trip the Hilo Project, the five American bikers were provided with vehicles by Ducati Vietnam. They started their trip in Saigon in early April, and made their way north to Hanoi.

The group made friends with bikers and other locals over the course of their trip even though only one of the bikers, Catherine Pham, was able to speak Vietnamese.

The group reported they wouldn’t recommend the trip to anyone but experienced motorcycle riders as the terrain is very technical and there just isn’t a lot of support out on the road.
