Aldi Satya Mahendra (born 27 June 2006) is an Indonesian motorcycle racer who is set to compete in the 2026 Supersport World Championship with AS Racing Team aboard a Yamaha. He is the reigning champion of the Supersport 300 World Championship, having won the title in 2024, and is the first and only Indonesian rider to win a motorcycle racing world championship.
Mahendra made his motorcycle racing debut in 2015 at the age of nine, racing in the Indonesian Racing Series. He would move to the international road racing scene in 2019, competing in the Asia Road Racing Championship for Yamaha Racing Indonesia, and moved up to the Asia Production 250 class for 2022 after spending 2021 away from the racetrack due to the COVID-19 pandemic.
As the reigning SSP300 world champion, Mahendra is set to step up to the FIM Supersport World Championship with a Yamaha-supported team for the 2025 season.
Mahendra is the son of Dicky Hestu Prahendra and Desy Prasanti, both of whom competed in motorcycle racing at a national level in the 1990s. His older brother, Galang Hendra Pratama, is also a professional motorcycle racer.
