In a statement, the MCUI (Ulster Centre) said the ‘unavoidable’ decision had been taken due to the coronavirus pandemic.
The statement referenced the cancellation of the Tandragee 100 and North West 200, and said the Cookstown 100 was still scheduled to go ahead in September, with Armoy set to run as planned at the end of July.
It continued: “Earlier this week two of our flagship’s events were cancelled due to the pandemic, Tandragee 100 and the NW200.
“The Cookstown 100 are planning on running again in September as they managed to do in 2020. Armoy Road Race club are still hopeful of running on their end of July date.
“Our first tarmac event is now planned for 5th June at Kirkistown, the first round of the Ulster Superbike Championship (USBK) and with several more rounds planned between June & October.
“The Trials section had already planned to run into the summer months and will release more details in due course.
“2020 was almost a wipe out of all our events with only one Road Race and one short circuit managing to run between the restriction and only with authority from Government departments.
“This announcement will be very disappointing for our Licence holders, Clubs, and supporters, but we must do what is best to keep everyone in the communities safe.”
All Irish road races in the Republic of Ireland have been cancelled in 2021, with the exception of the Skerries 100
