Like Honda, Yamaha is benefiting from the operational and technical advantages approved at the end of last year in an attempt to help the manufacturers most in need from a performance point of view.
One very beneficial aspect of the concessions is the possibility for the race riders to carry out private test days, limited only by the number of tyres available, which has also increased.
Another advantage is to be able to develop the engine which, unlike the constructors without concessions, is not frozen.
Since the beginning of the year, Honda has been following an extensive testing programme, with around 22 private events scheduled - although it is unlikely all will be completed as the concessions will be recalculated during the summer break, depending on the results obtained until then.
So far, Honda's Luca Marini has made the most of these concessions, and before the Portuguese GP was testing at Jerez to speed up his adaptation to the RC213V.
Yamaha was not as aggressive initially, the Iwata-based company setting a roadmap with the European calendar as a reference.
Fabio Quartararo and Alex Rins stayed at Portimao on the Monday after the last race in order to improve the performance of the bike which has so far not allowed either rider to finish in the top five in the two rounds held so far.
One of the aspects that has weighed Yamaha down the most in recent years is the lack of punch from its engine, prompting it to engagethe services of Marmotors - the consultancy firm owned by renowned engine engineer Luca Marmorini, known for his time at Ferrari and Toyota in Formula 1 as well as Aprilia in MotoGP.
