The World Superbike Championship will switch from its two-race Sunday format to holding Race One on Saturday and Race Two on Sunday in 2016, according to a FIM announcement.
According to the revised schedule, both WSBK races will start at 1:00 PM local time, with Superpole qualifying sessions, to be held on Saturday mornings instead.
In another change, the World Supersport riders will be using the Superpole qualifying format, with the World Supersport Superpole sessions run directly after the World Superbike Superpole.
The FIM say that the changes have been "aimed at creating a flexible time schedule for fans to enjoy a more complete and exciting WorldSBK experience from Friday morning to Sunday afternoon".
In all likelihood, the reason for the changes is for maximum possible TV benefits.
By missing the late afternoon Sunday major live sports programming times, Dorna hopes to maximize TV revenue by making the WSBK TV package more amenable to broadcasting networks and generate better revenue.
Better TV distribution opens the door for increased chances of sponsorship for the series and the teams.
