In 2013, Brivio joined Suzuki MotoGP as testing team manager ahead of their re-entry to the MotoGP class. When in 2014 the manufacturer officially announced their participation in the series starting from 2015, Brivio was named to be team manager of the revamped efforts. Brivio placed a focus on signing younger promising riders from lower classes in order to develop them to fit with the Suzuki team and bike. After a solid first season in 2015 with consistent points finishes for both riders, Brivio and Suzuki experienced their first successes in the class in 2016 with sophomore rider Maverick Viñales taking a podium in the 5th round in France and a win in Great Britain, followed by two more podiums to close out the year. With this success, the team however lost their development concessions, leading to a difficult 2017 with only sporadic points finishes and subsequently regaining their concessions. A return in form in 2018 saw the team achieve 9 podiums that year, and in 2019 Álex Rins took two wins in America and Great Britain.
