The Thai race, which made its debut on the calendar last season, was originally thought to be grouped with another of the Asian flyaway races to break up the traditional triple-header of Japan, Australian and Malaysia.
However, Thailand has now been moved to the second slot on the schedule on March 22, with the season kicking off in Qatar on March 8.
This means the triple-header flyaway portion of the calendar will remain intact for ’20 from October 18 to November 1, with the Aragon GP taking over the early October slot formerly held by Thailand.
Austin will return to its original pre-Argentina slot two weeks after Thailand, with a fortnight splitting the race Americas and Argentine Grands Prix.
Like this year, the French, Italian and Catalan Grands Prix will follow, while the German race at the Sachsenring will swap with the Dutch TT and will run on June 21.
The first Finnish Grand Prix since 1982 will round off the first half of the season on July 12, with the Czech and Austrian GPs running back-to-back when action resumes at the start of August.
The British Grand Prix at Silverstone – which extended its deal to host the race to the end of ‘21 following a complete resurfacing – will once again likely take its place on the August Bank Holiday weekend, with the San Marino race at Misano following.
The season will once again conclude in Valencia in the middle of November, bringing to a close the longest campaign in MotoGP history.
