Kamala Police Volunteer Paul Edden said Mr Stone had been at the Aussie Pub and then left, before crashing his bike into the median barrier outside U La La restaurant.
Mr Stone, who had lived in Kamala for around seven years, died on his way to Patong Hospital.
Bar owner Nick Ryan, who witnessed the crash, said Mr Stone was well known in Kamala and owned a guesthouse in Patong and a landscaping company in Kamala. He was originally from Melbourne.
“He was a larrikin character. He would never do wrong by you,” Mr Ryan said.
