A hypothetical question that I'd really love to know the answer to:
It was well documented at the start of Long way round that both Ewan and Charlie wanted KTM adventures for the trip, and only went for the BMW GS when KTM turned them down.
Now supposing KTM had approached them at the start of Long way down and offered new KTM Adventures for this trip (Bit of grovelling, can see now they were serious, greatest respect for what they achieved etc.), do you think they would have stuck with BMW for LWD, or would they be up the road looking for new orange tee shirts?
Ignore potential contractual issues etc, put yourself in their shoes and think what you'd do?
