Casey Stoner admits his wrist is continuing to prevent him from working on the set-up of the Ducati GP9, desp🍬ite the former champion going quickest on the second day of MotoGP pre-season testing at Sepang, Malaysia.

Still reeling from the effects of his wrist surgery towards the end of last year, Stoner was noneth🧔eless on fine form as he swept ꦕto the top of the timesheets with the quickest lap of the test so far.

However, aꦗfter completing just 29 laps over the course of the day, the least of any rider, Stoner has revealed the pain is forcing him to complete just short bursts of laps be🦂fore he is forced to take a break.

It means that, despit🍎e his quick lap times, he is unable to spend enough time on track to establish a good set-up on the latest evolution of the Desmosedici. It is a situation he is frustrated with.

"The wrist is giving 💖me a lot of problems and I can't manage more than two or three laps at a time, so it's difficult to work on set-up because I'm having to break off too often.

Nonetheless, Stoner🐲 is remaining positive, adding that the bike has improved through the day, while he i𒅌s certain he is well on the way to full fitness.

"We've still managed to do some work on improving the feeling on the GP9, with some changes to the rear set-up that have improved the bike in the areღa we were suffering the most. Now it is much easie🧸r to ride.

"I still can't ride how I want though and we really need to s꧟tring a run of consistent laps together, although I know that if I can get a little closer to 100% fitness that problem will be resolved. Hopefully the wrist will feel a bit better tomorrow so that I can try and do a longer run and confirm the positive feedback we've had from the bike today."
