The Russian race was cancelled last year due to lack of funding plus the political situation between Russia and the Ukraine.
This year the same reasons have been used for the July 5 event being scrapped.
A press release confirmed the race being cancelled. "Dorna WSBK Organization and the FIM, Fédération Internationale de Motocyclisme, regret to inform of the cancellation of the Russian Round scheduled to be held at Moscow Raceway on July 5th 2015.
"The Russian event promoter, YMS Promotion, has not provided the required contract guarantees defined by DWO to confirm and implement the event organisation.
"The Round will not be replaced and the 2015 WSBK Calendar will consist of the 13 confirmed events… As a consequence, the Moscow Region Yakhnich Motorsport Team which applied to the FIM Supersport World Championship will not participate in the series for the 2015 season."
