The three-time grand prix winner was forced to retire from last Sunday’s race at the Buddh International Circuit when his RS-GP broke down.
Espargaro was at a loss to explain what the actual problem was, but noted that this is a recurring issue for Aprilia at hot venues.
“I don’t know, the bike stopped,” he said of his Indian GP retirement. “It’s a shame. Every time that it’s really, really hot, we suffer. It’s not the first or second season. It’s something we have to improve.
“The bike was boiling, it was very difficult to ride. The bike was competitive to ride but difficult due to the heat.
“But I was good, I was riding really good, really fast in 1m45s high, I had more rear tyre than Brad [Binder] and Joan [Mir].
“So, I think the fourth place was quite OK, but we could not take it.”
Asked if he was worried about this going into the remaining races, which feature extremely hot stops in Thailand, Indonesia and Malaysia, Espargaro said: “Yeah, it is, but every season is the same when we go overseas.
