Investigation Reports KTM Motorcycles Modified After EU Certification

A media consortium including Le Monde published an investigation stating that Austrian manufacturer KTM supplies some motorcycles with speed and power restrictions installed to meet European Union certification requirements. The report said the motorcycles are then modified after testing.

A manager at a major French KTM dealership stated in December 2025 that all motorcycles arrive restricted but the restriction is removed for the engine to function, and that KTM delivers them with a different exhaust system.

The dealership manager said the restricted mode exists only to pass European tests and anti-pollution standards. The investigation described the practice as an open secret within the industry that had not been disclosed to national and European authorities.

The report linked the modifications to increased polluting and noise emissions beyond certified limits. It stated that the motorcycles are sold in an optimized, non-certified version after the tests are passed. The investigation was initiated after the NGO Climate Whistleblowers received a report from a motorcycle industry professional alleging practices that could affect the environment and public safety.
