Mika Kallio
In early 2018 it was announced that Zarco would ride for the factory KTM team on a two-year contract from 2019. Following a difficult start to 2019 season where he struggled, managing barely to finish within the points-scoring positions, Zarco and KTM made the shock announcement at their home Austrian Grand Prix that they had reached a mutual agreement to end Zarco's contract prematurely at the end of the season. Despite initial intentions to complete the season with Zarco, KTM elected to release him unconditionally two races later after the Misano Grand Prix and replace him with test rider Mika Kallio for the remainder of the season, citing "lost hope" in the situation with Zarco's "negative attitude" before his impending departure.
