The 20-year-old from Townsville made the jump from the Moto3 world championship, where he finished runner-up last year, directly to MotoGP, bypassing the Moto2 category altogether.
Miller’s 1000cc Honda RC213V-RS MotoGP bike is twice as heavy and has four times the horsepower of his Moto3 KTM, and is 100km/h faster down the straights.
Speaking to the ‘Keeping Track’ podcast, Miller said 2015 has been a steep learning curve.
“It’s almost like learning to walk again. It’s a different style – there’s no two things you can even remotely match,” he said.
“Everything’s different, the way you ride it, the way you go into a corner, the way you hang off – no two things are even close to being the same.”
Miller has a three-year contract with Honda, which fields reigning MotoGP world champion Marc Marquez and fellow Spaniard Dani Pedrosa amongst its riders this season.
The Australian says Honda has been patient with him as he learns to cope with MotoGP machinery, but admits going from challenging for the Moto3 title to fighting in the midfield has been difficult.
“It’s taken a lot of mental strength,” Miller says.
“We came out of an awesome season last year where we were winning races, but we knew what we were getting into when we came into this … it’s back to square one, basically.”
Episode 42 of the ‘Keeping Track’ podcast also spoke to reigning world champion Marquez and two-time MotoGP world champion, Yamaha’s Jorge Lorenzo.
