Due to no replacement circuit being found for Monza, World Superbike organisers have confirmed the round will be axed from the 2016 calendar.
Despite being returned to the calendar during the winter, Monza ultimately needed more time to make the changes required to ensure it was ready to host a World Superbike race and ensure the safety of all the riders.
It was hoped the Vallelunga could stand in as a replacement, but the circuit could not be used due to scheduling problems.
Vallelunga would also have required modifications to be able to host a championship round of WSBK, and the changes would have needed more time to implement than was available.
Reports suggested that organizing bodies were in talks with Portuguese circuits Portimao and Estoril about stepping in as a late replacement, but they appear to have fallen through.
The end result is that this year’s World Superbike Championship will now only consist of 13 rounds.
Following the US round at Laguna Seca on July 8-10, the series will now take a two-month break before returning at the Lausitzring in Germany on September 16-18.
