For 2008, Chris Vermeulen was joined by Loris Capirossi as the rider lineup and the same lineup remained in 2009. For the 2010 season Álvaro Bautista joined the team.
For the 2011 season, the team fielded only one GSV-R for Bautista with no replacement for Loris Capirossi, who moved to the Pramac Racing team. At the end of 2011 Suzuki pulled out of MotoGP citing the need to reduce costs amid the global economic downturn.
