KTM has finally been able to 'revitalise' its MotoGP engines following reliability issues in the 2026 MotoGP season. In a procedure that began last Monday at the brand's engine production centre near Mattighofen, its engineers and technicians opened the engines that caused so many headaches during the first part of the season.
During the process, the parts that supposedly caused the failures were replaced and the units were resealed, in order to reintroduce them into rotation for the remainder of the campaign, starting with this weekend's Aragon Grand Prix. As Autosport revealed earlier this month, the other manufacturers in the championship gave KTM their approval to open the engines, with strict security measures and supervision of the FIM.
Although nobody has so far confirmed which parts have been replaced, everything suggests that the origin of the problems could be found in the pneumatic valves fitted to each engine. This component was what penalised Yamaha in 2020, when a supplier defect altered the size of the M1's valves by hundredths of a millimetre. Yamaha also received the approval of the other manufacturers at the time to unseal its engines.
Each power unit on a MotoGP bike has four cylinders and 16 valves. In addition to replacing each of the valves, once an engine has been opened, some elements, such as washers, gaskets, lubricants and other details must also be changed, turning each of the seven opened power units into practically new components. Since the problems began to emerge, KTM made the decision to limit engine power in some races, but it is unclear if KTM will continue to do so after recent fixes.
Particular attention has been paid to the four engines in Pedro Acosta's rotation. The Spaniard's bike stopped unexpectedly on several occasions this year, with the accident he caused at Barcelona being especially dramatic. KTM has since limited the engine revs on his bike. So far this season, Acosta has opened six units, of which two are already out of the rotation, leaving him with the four now opened, and two more (up to the eight allowed by the regulations) that have not yet been unsealed.
With these fixes, KTM hopes to return to competitiveness and finish the season without technical disruptions. This move also tests the trust among manufacturers in MotoGP, where collaboration and mutual approval are key in emergency situations like this.
