Pramac Racing team principal Paolo Campinoti also heaped praise on the Aussie rider, emphasising the rider's contributions to the team. \"Some riders pass through a team, while others leave a lasting mark on its history, and Jack certainly belongs to the second group. Over the time he has spent with us, he has become an important part of the Prima Pramac story, both through what he has achieved on track and through the person he has been within our team,\" Campinoti said. <\/p>\r\n\r\n
\"We are naturally sorry that our journey together is coming to an end, but this is part of the decisions that have to be made in our sport. We wish Jack and his family every success for whatever comes next. The door will always be open for him, because once you're part of the Prima Pramac family, you'll always be part of it,\" he added.<\/p>\r\n\r\n
