Electronics and rear suspension worked on by Mir, Guintoli compares swingarms

Joan Mir used the Catalunya MotoGP test to predominantly work on the rear suspension and electronics of his GSX-RR, as Suzuki were limited to just minor new parts.

Joan Mir finished the one-day Catalunya MotoGP test fourth quickest for Suzuki, but remained without any significant updates to his GSX-RR. 

With Alex Rins sidelined due to his bicycle crash before the Catalunya race weekend began, Mir was joined by Suzuki test rider Sylvain Guintoli for the one-day test. 

"It’s been a good day of testing, we didn’t have a lot of things to try but we worked on geometry settings, things like my riding position on the bike, and electronics and it was all positive,” said Mir. 

"I also worked a little bit on rear suspension and the rear shock. I was able to give important feedback and information to the team about a few areas, and now they will work on all of that while looking at the data.

"I’m happy with what’s been done but it’s been a tiring couple of weeks and I’m ready to go home and start my preparations for Germany."

Mir secured a solid fifth place finish during the Grand Prix on Sunday, but was then elevated into fourth after Fabio Quartararo’s late penalty. 

For Guintoli, this was his first time on the bike since pre-season testing in Qatar, as he compared different swingarms for the Japanese manufacturer. 

Guintoli added: "This Catalan test has been a real pleasure for me, I haven’t ridden the GSX-RR since the test in Qatar and it was so nice to be back with it again. 

"My feeling was really good today, I was a bit worried that after so long off the bike and with everybody else fresh from racing, that I would get thrashed in terms of lap times! 

"But in fact I had very good feedback from the bike and the tyres, and I was able to complete the day’s programme really well with 72 laps completed and a really solid test. 

"I did some comparisons and worked on a wide variety of things, including the swingarm. Now I’m going to race in the Le Mans 24hrs and riding the GP bike today has got me fired up for that."
