Australian Jack Miller won his first national dirt track title at age 10. Miller moved into road racing in 2008, and made his road race debut in Tasmania in 2009 at 14, which led to him competing in the 125cc Australian Championship in 2009.
He won the MRRDA 125cc series and subsequently moved to Europe, where he competed part-time in the 125cc World Championship, part-time in the 125cc CEV Buckler (Spanish) Championship, and full-time in the 125cc IDM German Championship which he won handily.
Miller rode a Caretta Technology Honda NSF250R in his first assault on the first Moto3™ World Championship, yet switched to Racing Team Germany for 2013 with the FTR-Honda machine.
That year Miller impressed sufficiently to make the switch to Aki Ajo’s factory KTM outfit for 2014 – stepping up his game to win six races and to take the title battle down to the last race of the year, only to just miss out to Alex Marquez.
For 2015 Miller made the jump straight up into MotoGP™, riding an Open Honda for CWM LCR Honda in his premier class debut season. It was a season filled with crashes but Miller ended 19th and as the top Open Honda with a best finish of 11th in Barcelona and a strong ride to take the Open class win at home in Australia.
For 2016 Miller continued on his three year HRC contract, moving to the Marc VDS Racing team on a factory Honda.
