Monster Energy Yamaha MotoGP and Petronas Yamaha SRT are in deep engine trouble after only two rounds of the MotoGP™ World Championship. The two premier class outfits are the only teams on the MotoGP™ grid to have used more than two engines across Rounds 1 and 2, with none of Yamaha's four riders using either of the engines that they used at the Spanish Grand Prix seven days later at the Gran Premio Red Bull de Andalucia.
Maverick Viñales is the man worst off, with the Spaniard having used three engines last weekend, one of which was withdrawn from their allocation after FP3. He's now using his fourth and fifth engines, which must see him through to the end of the season to avoid penalty. Valentino Rossi, meanwhile, has also had one engine withdrawn after an issue with one of his power units brought his Spanish Grand Prix to an end seven days ago.
The same issues are also apparent at Petronas Yamaha SRT, with both Fabio Quartararo and Franco Morbidelli onto their third and fourth engines already. The latter was the victim of engine trouble on Sunday at the Andalucia GP after looking odds on to claim his first podium in the premier class, with fears then turning towards Quartararo's machine in the hope the Frenchman wouldn't suffer the same fate while leading.
If any of the four riders are forced into using a sixth engine, then they will start that race from pitlane as a result. Rumours are Yamaha sent at least two engines back to Japan following the season-opener and it's clear with this latest news they need to find solutions to what seems to be some worrying reliability issues.
