The Tokyo manufacturer’s decision comes as Espargaro’s future with the team is uncertain.
New parts brought to Mugello last week were a swingarm and chassis, with one of each fitted to Marquez’s RC213V.
After it was announced that the six-time world champion was to undergo surgery and be sidelined indefinitely, Honda decided that these parts would be passed on to Japanese satellite team rider Takaaki Nakagami, rather than the Marquez’s teammate.
Espargaro said Thursday: “At the last race, Marc was testing a new chassis and a new swingarm, in particular this last part has been improved, more than the chassis, and Honda’s decision is to pass the parts to Taka, who is also a factory pilot.
“I will continue to fight with the tools I have, as I have done since the start of the season and that’s it, that’s it.”
Espargaro said he accepted Honda’s decision to give the part to an LCR satellite team rider, and said “you’ll have to ask the person responsible, it’s not my job.”
“It’s not for me to ask myself these questions, Honda made a decision and I respect it,” he said Thursday in Montmelo.
“I’m a rider and I have to ride as fast as I can and that’s what I try to do every weekend. The decision of who gets the hardware or who upgrades the bike is entirely up to Honda and you’ll have to asking the person in charge is not my job.

But he added: “Of course I want the latest on my bike and as much as possible to improve the situation, especially when the situation is not going well.
“What you want is to have a lot of new parts to straighten it out, that’s not happening and we just have a new frame and a new swingarm and Taka is going to use them.
“It is what it is, I’m not saying it in an angry tone or anything, it’s a Honda decision, I accept it and I will go as fast as possible with the bike I have. in the box.”
Despite the move, Espargaro said he “still felt loved by Honda” and remained “fully committed to the brand through the end of the year, and possibly with a renewal.”
He added: “But so far that’s the situation and I fully accept that. Taka is a fast rider, also very valid to try this stuff and he’s a lot more factory-related than me. , I understand that he has the opportunity to try new parts and I respect that.
