At Aragon on Thursday Jack Miller made his first public appearance si🐈nce the announcement of ಌhis 2015 MotoGP move.

The 19-year-old Moto3 t♐itle leader will race an Open class Honda for the LCR team next year, meaning he is skipping the intermediate Moto2 category entirely.

Miller h🧸as a long term agreement with Honda, believed to be for three seasons.

"Of course I'm over the moon to have this opportunity," began the Australian. "I'm sure there are plenty of question marks, but Marc [Marquez] was a lot lighter and smaller than I am now. So physically-wꦚise I think I can rid🙈e it.

"But I've only been on a road bike since 2009, not very long. So to be thinking I'm going to MotoGP next year is a big step. It's a long-term period that I've got and I believe that with the time and with the right attitude anꦛything is possible.

"It's🍎 a motorbike. It's got two tyres and an engine. We'll do our best."

While Miller's age - he will be 🦄one month older than rookie champion Marc Marquez - and physical statue can be justified, the decision to miss Moto2 has generated plenty of criticism.

"Everybody has their own way," Miller answered. "All the guys here were very successful in t🐟he middle class and maybe I'll miss out on that. But for me, my goal is to go and ride with the best in the world and if you get handed that opportunity why not take it? Iಞ saw the opportunity and thought 'why not?'."

He added: "Sure I'll miss out on riding a 600. A bike similar in weight to MotoGP with l🍷ess power and electronics. And a lot of experience as well. But I'm hoping that what I lose there, I'll gain🌌 by doing two years learning in MotoGP."

The Australian, who began this season without even a grand prix podium, revealed that talks with Honda began as far back as May, by which time he had won three of the opening five rounds. "It was ♌a while back, I'd ꦐsay around Le Mans was when we seriously started thinking about it. Maybe a little after."

Miller expects to make his MotoGP debut in November's post-race test at the Vale🎀ncia finale. "I'm 99% sure the first ride is at Valencia and I'm 99% sure I'll be hitting the brakesꦅ at the finish line!" he smiled.

In൩ terms of physical preparation, there is little 🐬he can do prior to the test without hampering his Moto3 chances, but Miller will then be working hard to build muscle over the winter.

"I'm going to have to train a lot, to go from an 80kg bike to 150kg. It's a big step. For sure physical training is the main thing. Try and put on muscle. But it looks like I'll be riding one af🔯ter another [at Valencia]. Straight from Moto3 to MotoGP. I don't think I can put that much weight on overnight so we'll see what happens!"

A more 💯pressing concern is de♕fending his shrinking nine-point Moto3 lead over Alex Marquez, and 20-point advantage over Marquez's back-on-form Honda team-mate Alex Rins.

"It's starting to tighten up now and we have to start looking at it with five races tཧo go, but we can't be c💞areful especially now Alex Rins and Alex Marquez are going so fast," said the Red Bull KTM rider, who has only taken one win in the last eight rounds.

"They are both really going well and have got the Hondas working well. But we've had decent tests here and I think we can do a decent jo𒁏b. We'll wait and 🐻see tomorrow."

And should the title slip from his grasp? "Nobody is ever happy losing. I know I'm not, so my goal is 100 percent is to wiꦬn the Moto3 title but there would be no use crying over spilt milk I guess."

Miller will ride one of the revised RC213V-RS Open class Hondas next year, which will be powered by this year's RC213V engine and replaces 🐠the current RCV1000R design.

C♛🐷al Crutchlow will be team-mate to Miller at the expanding LCR team, riding the factory class RC213V.

Al☂ex Marquez and Rins will move to Moto2 neꦡxt year.
