Chantra to Substitute for Mir at Japanese Grand Prix
Somkiat Chantra will replace the recovering Joan Mir on the Honda HRC Castrol bike at the Japanese GP. Chantra, who raced in MotoGP in 2025, currently competes in WorldSBK and previously won at Motegi in Moto2. Mir's condition will be reassessed after the Indonesian round.
Chantra's return to MotoGP comes at a circuit where he has demonstrated prior success, having claimed a Moto2 victory at Motegi in 2023. His previous premier-class appearance at the same venue in 2025 yielded a 15th-place finish, giving him valuable familiarity with the RC213V on this specific layout. The Thai rider's current WorldSBK season has been hampered by injuries sustained in pre-season, yet he has still managed to score points in seven rounds.
Mir's absence stems from medical issues that emerged following the San Marino GP, prompting an extended observation period. HRC has indicated that the 2020 World Champion's status will be clarified after the Indonesian round, suggesting the team is taking a cautious approach to his recovery rather than rushing him back to competition.
This substitution could affect Honda's competitive momentum in the constructors' championship, as Chantra's limited recent MotoGP experience may impact results compared to the seasoned Mir. For fans in Thailand and across Asia, however, the return of the region's first premier-class rider may boost viewership and engagement with the Japanese GP. The decision also reflects broader trends in motorsport where teams increasingly draw on WorldSBK talent to fill gaps, potentially reshaping career pathways for riders between the two championships.
