Oxford Languages defines a disaster as "an event or a fact that has unfortunate consequences". That moment for Yamaha occurred back in July, when the MotoGP manufacturer used illegal engines for its four riders fitted with different valves to the ones homologated pre-season.
The Spanish Grand Prix weekend was one plagued by engine issues for Yamaha. Valentino Rossi was forced out of the season-opener when his motor expired, while Maverick Vinales lost engine two of his allotted five for the campaign in practice. Still, Fabio Quartararo won on the Petronas SRT M1 and Vinales trailed him home in second, making it appear as if all was rosy in the garden.
And, despite an issue for Franco Morbidelli in the Andalusian GP, an all-Yamaha podium headed again by Quartararo gave little cause for concern.
