The Isle of Man TT organizers are taking a critical look at the sidecar class, with a sustainability review in the works. This decision comes on the heels of a series of serious incidents, including a crash that left four-time race winners Ryan and Callum Crow's machine flipping and another that resulted in Maria Costello, MBE, and Shaun Parker's hospitalization. The review aims to address the safety concerns and assess the long-term viability of the sidecar class. Gary Thompson MBE, BEM, Clerk of the Course, emphasizes that the review is not a reactionary measure but a comprehensive assessment spanning multiple years, considering participation trends, technical development, and incident data. The organizers have invited feedback from teams, competitors, industry representatives, officials, and spectators, with a deadline of June 30th for written submissions. The final sustainability report is expected by the end of July 2026, and the sidecar class has been temporarily removed from the Southern 100 Races. This review highlights the organizers' commitment to ensuring the safety and sustainability of the event, even if it means making difficult decisions. The sidecar class has a rich history at the Isle of Man TT, but the recent incidents have underscored the need for thorough evaluation and potential changes to ensure the well-being of riders and the event's future.
