Customer of mine did 4,000kmaround Namibia on one, including 40km up a dry riverbed to view some elephants!
He made some little spacers - I have a pic somewhere - which gave extra clearance for the more-offroad-biased tires, bike performed flawlessly, and he got GREAT gas mileage to boot!
We are selling the country's first BASHPLATE, designed especially for us, that fits both the NC 700 as well as 750, proper aluminium BASHPLATE, will post pics from work, but it will really protect the bike.
Cheers
