Under the mentorship of multi-time World Champion Kenan Sofuoğlu, he shared the track in the Red Bull Rookies Cup during the 2013 and 2014 seasons with riders who are now among today’s leading stars. Razgatlıoğlu went on to dominate the European scene, securing the European Superstock 600 title in 2015, before finishing second in the European Superstock 1000 Championship in 2017.

After transitioning to the WorldSBK class in 2018, he rapidly established himself as a consistent frontrunner and regular podium contender. Toprak claimed his first WorldSBK victory in 2019 at Magny-Cours, winning the championship’s historic 800th race after starting from 16th on the grid. He further etched his name into WorldSBK history by also winning the championship’s 900th and 1000th races.

A move to the Factory Yamaha squad in 2020 proved to be a career-defining moment. In 2021, Razgatlıoğlu delivered a historic performance to clinch the WorldSBK Championship, ending Yamaha’s long title drought in the category and cementing his status as one of the sport’s global icons. After finishing runner-up with Yamaha in both 2022 and 2023, Toprak made a headline-making move by switching to BMW. Following dominant championship-winning campaigns in 2024 and 2025, the “Stoprak” phenomenon—renowned for his gravity-defying late braking and signature stoppies—decided he was ready for a new challenge.

Razgatlıoğlu is now set to bring his extraordinary talent to the premier class, rejoining the Yamaha family for the 2026 MotoGP™ World Championship. Competing with the Pramac Racing setup as a Factory Yamaha rider, he aims to redefine the limits of the YZR-M1 on the world’s most prestigious circuits.
