2020 was his first full season in the Moto3 World Championship, after having replaced his brother the previous year in several races. A year of adaptation and growth, it ended with him finishing seventeenth overall.
His first standout results in Grand Prix racing arrived in 2021, with three podiums and eleventh in the standings. Öncü continued to grow as a rider and established himself as one of the main competitors in the class.
In 2022 Deniz Öncü continued to rack up podiums and came very close to achieving his first victory. After once again being one of the most competitive Moto3 riders, he ended the year with 200 points, in fifth position.
In 2023 Deniz returned to Red Bull KTM Ajo. He began the season as one of the favourites for the title and was a regular in the top positions. His campaign kick-started when he achieved a run of three consecutive podiums, including his long-awaited first victory at the German Grand Prix. Öncü picked up two more victories in Austria and Australia and, after remaining in the title battle until the final rounds, enjoyed his best season to date with fifth place overall.
