there is only one piece of evidence online that shows Mr G Evans rode a Triumph Thunderbird from London to Johannesburg, 10,700 miles. And nothing else online about it at all.

no evidence of a book, image, magazine or newspaper article, and no photographs or video clips either.

That's what comes of a journey without a marketing campaign by sponsors to ballyhoo their products being used to carry on past expected ability in the face of danger and extreme conditions.

So, if you want to be famous, get some sponsors who have a lot of advertising.
