In November 2017 Where The Road Ends – A Motorcycle Documentary, a team of U.S. Army veterans will ride motorcycles from the Arctic Circle to the tip of South America, crossing the infamous Darien Gap. Here they are in Colorado testing a prototype side car.
TwistedThrottle.com has an article about settings the bikes up, and why they choose to use sidecars for some portions

Recently the team took one of their sidecars to bonneville and set a record for fastest Production 650cc sidecar, a class for which there was no existing record.

so how fast did it go?
72mph I believe, so 115.2km/h.
I’m sure a DR could beat that.
