By late August, KTM successfully addressed the reliability issues, identifying a faulty component reportedly from an external supplier in the pneumatic valve area. Although the technical fix is in place, the manufacturer faces logistical challenges due to depleted engine allocations. Previous failures resulted in two engines being withdrawn for Pedro Acosta and three for Brad Binder. Binder reported having only one fresh engine remaining before the 19th round of the season, necessitating careful management of his remaining units.

Following the Aragon Grand Prix, where Pedro Acosta secured a second-place finish, speculation has emerged regarding KTM’s engine specifications. While the RC16 motorcycles showed no obvious reliability problems during the race, rumors suggest the manufacturer may have intentionally kept engine RPMs lower to ensure stability. 

KTM riders may potentially regain 500 RPM at the upcoming Misano round. Pol Espargaro noted that increasing the rev limit would provide benefits beyond top speed, specifically aiding gearbox management and preventing the engine from hitting the limit prematurely.
