KTM has become the first MotoGP manufacturer to put its new 2027 engine on track, with Pol Espargaro sharing a video from a private Jerez test on social media.
Having fired up its new 850cc engine on the dyno for the first time in October, KTM has now taken another step in developing the successor to the RC16 for the 2027 regulations.
It’s no secret that manufacturers have already shifted significant resources towards the upcoming rule cycle, despite the 2026 season with current prototypes still ahead.
MotoGP is preparing for one of its biggest technical overhauls in decades, with regulations largely unchanged since the introduction of a common ECU in 2016. Further, 2012 was the last time manufacturers were required to change the engine capacity, as the series shifted back to 1000cc motors from the previous 800cc units.
While all factories have been working hard on building bikes for the new regulations, which also feature reduced aerodynamics, a ban on ride-height devices and a move to Pirelli tyres, none had run an 850cc power unit on track until now.
