Repsol Honda rider Marc Marquez says he is struggling overall with the RC213V after finishing more than one second behind Jorge Lorenzo on the final day of the Sepang tests on Wednesday.
Though there were slight improvements, Marquez feels they are far from where they want the bike to be due to mainly his struggles with the new spec-ECU.
Marquez finished third quickest with a lap time of 2m 01.047s on Wednesday, more than one second behind Lorenzo on the Movistar Yamaha.
“Today we had some problems, especially about the rhythm, because one lap here doesn’t matter and the weather stopped our plan, but the same for everybody,” said Marquez.
“It was a little bit easier to keep the pace but anyway, we are struggling and we are far from where we want to be. It’s a big question mark even for us because the problem for me is that with the electronics, we are too far from the level.
“It’s what I say already at the end of last season, with the new electronics maybe we will arrive at the first test and some manufacturers they will fix, or maybe some manufacturers will struggle more, so maybe we choose the wrong way but now we are trying to go in the correct way.
“I concentrated on the new engine, I didn’t compare again [to the 2016 engine he first tested at end of last season] because the difference on the first day was not so big.
“But it’s what I say – with the electronics we are far, but it means that if we are far with the electronics, it is difficult to compare things because the limit is in the electronics and we must fix.”
