Bayliss made a surprise return to the sport this season when he stepped in to replace the injured Davide Giugliano on the Aruba.it Ducati team seven years after announcing his retirement.
After a solid performance in the first round of the 2015 Superbike World Championship in Australia, Bayliss was retained for the second round in Thailand as Giugliano continued his recovery.
After finishing eighth and 11th in the two races at the brand new Chang International Circuit in Buriram on Sunday, Bayliss admitted that he is "ready to return to enjoying life with my family in Australia".
"All in all, and considering that conditions here are some of the most difficult I've experience, I can say that I'm fairly satisfied," he said. "I've never liked it when it's this hot and they were, as I expected, two very physical and difficult races, especially the first as I didn't even take a drink in my suit!
"I thought I'd do a little better in the second race but I knew it would be tough, so it didn't go too badly I guess… It's been fun, I came back in particular circumstances and wanted to do one more event after Phillip Island to see how it would go.
"I love racing, Ducati and the people that work here and it's been really great to race with the Panigale R Superbike.
"I was lucky enough to finish my career fit and healthy and I've seen that I can still be fast, but now I am ready to return to enjoying life with my family in Australia. I want to thank everyone for their support and now I leave things to the young talents."
With the third round of the Superbike World Championship set to take place in Aragon on April 12, it remains unclear whether Giugliano will recover from his injury in time for the event.
