KTM’s MotoGP engine woes traced to supplier quality control problem

KTM's MotoGP team is grappling with engine reliability issues, traced to a supplier quality control problem, requiring approval from rival manufacturers to make necessary repairs.

KTM's MotoGP engine woes traced to supplier quality control problem

The KTM MotoGP team is facing a significant challenge with engine reliability, with sudden shutdowns causing concern and disruption during races. The issue, traced to a supplier quality control problem has led to engines failing under certain conditions, putting riders at risk and affecting the team’s performance.

In a recent interview, KTM motorsport director Pit Beirer confirmed that the problem stems from high-stress parts in the powertrain that did not meet specified quality standards. These critical components have failed, causing engines to shut down unexpectedly. The most notable incident occurred during the Catalan Grand Prix where Pedro Acosta was leading the race when his engine cut out, resulting in a serious accident for Alex Marquez who was following closely behind.

Identifying the root cause of KTM’s engine problems

The KTM RC16 has experienced a range of technical issues this season, including clutch and ride-height device failures but the most concerning has been the sudden engine shutdowns. Beirer revealed that the problem lies within the engine, with certain components posing a risk. The engines affected by this issue cannot be used for safety reasons, and the team is working to address the problem during the summer break.

The engine freeze in MotoGP, which has been in place since the start of the 2026 season, means that KTM must obtain permission from rival manufacturers to make changes to the sealed engines. This process involves submitting a special application to the MSMA manufacturers’ association accompanied by detailed documentation. KTM has already received positive feedback from some manufacturers, but approval from all rivals is required before the replacement work can proceed.

The challenge of obtaining rival approval for engine repairs

KTM has thanked Aprilia for its support, but must also receive approval from DucatiHonda and Yamaha to carry out the necessary repairs. The approval process is not guaranteed, as rivals may be concerned that addressing the reliability issue could also involve reducing engine performance. KTM will need to demonstrate that the problematic parts are at risk of failing even with significantly reduced performance.

The latest MotoGP engine list shows that Brad Binder has had three engines withdrawn from his allocation, the most of any rider. Teammate Acosta has had two engines withdrawn, and Enea Bastianini one. Maverick Vinales is the only rider who still has all his engines available. The team is hopeful that they will receive the necessary approvals to address the engine issues and improve their performance in the upcoming races.
