Holan is the first fatality at the North West 200 since Malachi Mitchell-Thomas was killed in a Supertwins race in 2016, and he is the 20th to lose their life in the 97-year history of the event.
One of a number of international riders competing at the road race in Northern Ireland, Holan, who lived in Prague, first raced at the North West 200 in 2023.
His most notable victory came at the Manx Grand Prix in 2012, when he won the Newcomers ‘A’ race to become the first rider from the Czech Republic to win at the event.
Holan also raced at the Isle of Man TT and had a best finish of 20th in the 2018 Superbike race, and was a regular in European road racing.
In the most recent running of the Ulster Grand Prix in 2019, Holan had two 14th place finishes in the Supersport and Superstock classes.
Hefty74, Holan’s team, led tributes to the Czech rider, saying “above all he was a wonderful friend and a man of great character”.
“Kamil, you were an inspiration, support and a partner in life and on the track. Your humility, passion and smile will be missed every second,” Hefty74 posted on Facebook.
“Your legacy will live on in Hefty74 and in our hearts. We express our deepest and most sincere condolences to his entire family and all his loved ones”.
Race organisers have confirmed the races that were originally planned for Thursday night will not be added to Saturday’s six-race schedule.
The North West 200 is an international road race that takes place on 8.97 miles of closed public roads on the north coast of Northern Ireland, between the towns of Portstewart, Coleraine and Portrush.
Station Corner is a fast right-hand bend on the road between Portstewart and Coleraine.
