Jack Miller was unperturbed after sliding off three times during the Valencia MotoGP test as the Marc VDS Honda rider found his limit with the new Michelin tyres.

Miller, who joins Tito Rabat in the team on the RC213V, was 16th fastest as the test concluded on Wednesday after setting his personal best lap time in 1m 32.100s.

The Aussie used the factory electronics system and after completing his debut year in the class with the official MotoGP ECU, Miller was especially impressed with the 'old' software package, even though he will be forced to switch back the control ECU at the Sepang tests next February.

"I've really enjoyed my time on the new bike over the two days; the electronics and the seamless gearbox make a big difference," said the 20-year-old.

"You don't have to worry about keeping the bike in a straight line or it stepping out unexpectedly, so you can focus on the other things, like trying to hit the same line on every lap.

"I felt smoother and smoother on the bike with every exit and that was reflected in the consistency of my lap times. Unfortunately we had three small offs, but that's to be expected when you're pushing on new tyres," he added.

"The Michelin tyres are great, but they are very different in character to the Bridgestones and we will need time to make the transition.

"Getting a feeling for the tyres has been one key point of this test and going fast has been another."
