Moto3 title runner-up Jack Miller made his MotoGP debut during the start of testing at Valencia on Monday.
The Australian teenager is jumping straight from a 250cc KTM (55hp) to 1000cc Open class Honda (240hp), which he will ride alongside Cal Crutchlow at the LCR team next season.
Miller took six wins in Moto3 this year, more than any other rider, but was left just two points behind champion Alex Marquez.
Miller is riding the 2014-spec Honda RCV1000R, rather than next year's RC213V-RS.
