Team Suzuki Ecstar’s Alex Rins is optimistic after taking to Catalunya’s MotoGP test with an updated chassis for his GSX-RR contender.

The new chassis, which was debuted by test rider Sylvain Guintoli at the weekend’s Catalan grand prix, has offered Rins an improved feeling with the bike, particularly under braking.

While acknowledging the positives, Rins still believes there are improvements that can be made in the earlier stages of its development.

“Today I found that the modified chassis had a lot of positive points, but also there are some things about it that I would like to improve,” Rins explained. “There’s not a lot to change with it, but we will evaluate it further to try and get the best from it. I’ve done quite a lot of laps today and in general I think we can feel very positive about the way things are going.”

Rins finished the test fourth on the timesheets, as Maverick Vinales (Monster Energy MotoGP Yamaha) was fastest.
