After managing just six laps due to rain on Tuesday, retired double MotoGP champion Casey Stoner put in a 'productive' 47 laps during the final day of his return test with Honda at Motegi.

The first of his four tests to help develop next year's factory and privateer versions of the RCV, the 27-year-old Australian began by trying 'a few small items' on the present bike.

Stoner then switched to the 2014 prototype - as briefly debuted by Dani Pedrosa and Marc Marquez in testing at Aragon in June - during the afternoon.

No laps times were released by Honda.

"Thankfully today the weather improved a lot, in fact it was pretty hot, and we were able to get some good track time and work on our test programme," said Stoner, who retired from MotoGP at the end of last season.

"We had a productive day in general and thankfully the test plan wasn't too hectic, so we were able to get most of it done today, after yesterday's washout. It was great to see the team, even if there were only a few people here, and I thank Honda for all their support as ever."

Cristian Gabbarini, Stoner's crew chief at both Honda and Ducati, also travelled to Japan for the test, but Stoner insisted he has no plans to make any MotoGP race appearances.

"It felt really good to get back on the bike after nine months and I'm happy with how the test went, but it doesn't change my mind about the wild-cards - this is not something I am planning to do," he declared.

"Over the course of Casey's two-day test, we've been able to gather a vast amount of data and ideas for development," added HRC Executive Vice President Shuhei Nakamoto. "Consequently, we aim to increase our pace of development and hope that this, in turn, will lead to us winning this year's Championship.

"We focused exclusively on the RC213V, but in future tests, we'll get Casey to test-ride the tentatively named MotoGP Production Racer and assist in raising its level of performance even further."

Nakamoto did not reveal the exact date of Stoner's next test, but all are due to be held at Motegi, where the Japanese MotoGP round will take place in October.

Stoner took 38 MotoGP wins between 2006 and the end of 2012, claiming Ducati's only world title to date in 2007 and then a second crown at Honda in 2011. His 2012 title hopes ended with serious ankle injuries at Indianapolis.

However Stoner's decision to retire had been taken much earlier in the season, just before round four at Le Mans, when he stated that MotoGP "has changed to the point where I am not enjoying it."

Stoner has been competing in the support class of the Australian V8 Supercar championship this year. Stoner's rookie replacement at Repsol Honda, Marc Marquez, currently leads the world championship by 16 points from team-mate Dani Pedrosa.

Test teams from Yamaha and Suzuki, which is planning a MotoGP return in 2015, were also present at Motegi. Meanwhile, Factory Yamaha riders Jorge Lorenzo and Valentino Rossi start testing at Brno in the Czech Republic today (Wednesday).
