Makes me nostalgic, I've done something very similar across two mountain tops in Papua New Guinea with 1000' drops and the narrow track wiped out in several places.
We used similar Enduro bikes. Got printed pics but no vid, was about 15 years ago.
When we got to the top of the second mountain we hit a tribal clan that had never seen a motorbike, with good reason. We had to have fuel flown into an airstrip hardly bigger than a football field with a sheer drop at the end. The aircraft became 'airborne' when it ran out of strip.
At the bottom of the cliff was an Aussie Nomad belonging to the local defence force that didn't make it.
Our ride made the local papers as a 'first'.
