"We are thrilled to welcome Toprak back into the Yamaha family.
Toprak, the most victorious Yamaha rider of all time in Superbike, has proven to be an exceptional talent, securing the WorldSBK Title twice, which is no mean feat.
His transition to MotoGP is both a 'homecoming' and an exciting new challenge that's been set up with the clear goal of progressive growth over time.
His fighting spirit and determination are a perfect fit for both the Prima Pramac Yamaha MotoGP Team and Yamaha's bold MotoGP strategy, so we believe 2026 is the right time to make the move that many fans have been waiting for."
