Galang Hendra was born in Yogyakarta, Indonesia into a racing family, with both his parents competing on track. He started riding motocross at the age of seven but ended up following in his parent's footstep and made his road-racing debut when he was ten in 2009.
He graduated through the smaller class of the Indonesian national championships, putting in some exceptional performances along the way to mark him out as a talent for the future.
In 2015, Galang Hendra became an official Yamaha Racing Indonesia rider in the newly formed Asian Road Racing Championship AP250 Championship, finishing in ninth in his rookie season onboard the Yamaha R125. His impressive performances continued into the 2016 season and saw him selected to take part in the second edition of the Yamaha VR46 Master Camp, spending a week learning from his idol Valentino Rossi and his team, in just one of the many schemes the bLU cRU project undertakes to help to bring through the next crop of future world champions. That year he went on to finish fifth in the highly competitive ARRC AP250 Championship and in 2017 he finished sixth overall in the same championship, winning his first race towards the end of the season.
Galang Hendra took part in two WorldSSP300 rounds in 2017 as a wildcard, impressing at Portimão before a technical issue forced him to retire during the race and then sensationally winning the final race of the year at Jerez. The following season the Indonesian rider contested a full season in WorldSSP300, picking up another race win in Brno on his way to finishing tenth in the championship.
Galang Hendra returned for a second full season in WorldSSP300 in 2019, racing once again for the Semakin di Depan - Biblion MotoXRacing Team. He showed real promise and took two front row starts including a pole position with a best finish of fourth.
2020 sees Galang Hendra graduate to the Supersport class, lining up alongside Andy Verdoïa again at the newly named bLU cRU Yamaha WorldSSP Team on the R6.
