Leading MotoGP rider Jack Miller has swapped out his Ducati GP19 for a Ducati Panigale V4 R during an open track day in Spain.

The Australian, currently in his second season within the Ducati stable as a Pramac Racing rider, was at the Circuit de Barcelona-Catalunya as part of an open test featuring Moto2 and Moto3 riders.

As such, Miller took the opportunity to ride the machine that is well on course to give Ducati its first WorldSBK riders’ title since 2011 following a run of 11 wins from 13 races in hands of ex-MotoGP rider Alvaro Bautista.

No official lap times or comments were made, with a Ducati spokesman did confirm its MotoGP riders have been given a Ducati Panigale V4 R road bike for personal use on track days at their pleasure.

Miller, who has competed in the MotoGP class since 2015, is currently sixth in the overall standings after securing a trio of top five finishes so far this season.
