Yamaha Tech 3's Bradley Smith struggled for corner speed with a full fuel load in the first half of the Argentina MotoGP before making progress later in the race, eventually finishing in seventh place.
It is not an unfamiliar problem for the young British rider, who dropped back to ninth on the opening laps until he improved his pace in the second half of the race on a lighter fuel load to match his qualifying position at the flag.
“It was a tough challenge today, but overall I am pleased to once again finish with a decent position. Unfortunately, my start was not ideal and the race was actually a similar scenario to Austin,” said Smith.
“My pace at the end was exactly where it needed to be, as I started to do low 1m 40s laps, but as usual I struggled during the first half of the race when the bike is on a full fuel load. It happens on different race tracks, with various set-ups and on all types of tyre, so it seems that I have to find a way to adapt better.
“I just can't ride with the same corner speed and I'm not as smooth as I am at the end of the race,” added the 23-year-old, who finished one place ahead of team-mate Pol Espargaro.
“But we already have some ideas and will work on it in Jerez as I know I am there in terms of performance.
“Altogether the team and I are doing a really good job, but we just need to find that missing piece for Jerez, where we can hopefully make amends and can challenge as the leading satellite MotoGP bike which is the main aim at the moment.”
