The current two-weekend break between the Brno and Misano MotoGP rounds is the same length of time as for the official summer break.
The difference during the 'autumn break' is that testing is ongoing, with Honda, Yamaha and some CRTs attending an official post-race session on the Monday after Brno, while Ducati held a private two-day test at Misano.
The testing split will continue this week, with Honda and Yamaha attending a private two-day session at Aragon on Tuesday and Wednesday, with Ducati opting for unofficial laps at Mugello.
Aragon will mark the second MotoGP test of the year at the Spanish circuit, following a single-day in early June, which was a replacement for the cancelled Estoril test. Repsol Honda did not attend that test.
The circuit will also host round 14 of the championship at the end of September and the main focus at this week's outing will be on title contenders Jorge Lorenzo and Dani Pedrosa, plus Repsol Honda stand-in Jonathan Rea.
Lorenzo tried an early 2013 Yamaha prototype at the Brno test, but didn't feel any benefit over his present machine. Further upgrades are expected for Aragon.
Pedrosa, who switched to a 2013 Honda prototype in late July, is likely to seek a continued cure for the long-running chatter problems, while temporary team-mate Rea will be making his second appearance for the Repsol team.
The 25-year-old Ten Kate Honda WSBK star has been called up to replace the injured Casey Stoner at the next two races, Misano and Aragon, barring an early return for the Australian.
Rea, whose only previous MotoGP experience was a private test on an 800cc Honda in 2010, completed 61 laps at Brno with a best time 3.145s behind fastest man Cal Crutchlow (Tech 3 Yamaha).
