Conor Cummins will contest the Supersport and Superstock classes at the Isle of Man TT with Padgetts Honda, the team have announced.
The Manxman will continue to campaign his Honda CBR1000RR Fireblade SP in the Superbike and Senior races with the Honda Racing factory team.
"I'm absolutely thrilled to have Conor on board," said Clive Padgett.
Of the last 39 TT races that the team has started around the Mountain Course, they have won 11.
Padgett added: "When it looked like it might come about, I didn't have to think twice.
"He's the perfect addition to the team. We're currently building his bikes and look forward to getting to the TT."
Cummins said: "They have a record that's second to none around the Isle of Man. I'm really excited about representing the team and it will be a real honour to ride in the famous team colours."
