It's no surprise when you think that similar constructed belts are used in most cars for many thousands of miles more and those engines have conventional spring loaded valves, so they are working much harder than they ever would in a Desmo engine, where the cams can easily be rotated by hand?

Conspiracy theory alert, but I think it could be a carefully constructed myth by Ducati to generate revenue for service parts that don't actually require replacement in most cases. Me paranoid? lol
