According to MotoGP.com, Suzuki will not be participating in the 2012 MotoGP Racing season. Suzuki cites tough circumstances mainly caused by the prolonged recession in developed countries, a historical depreciation of Japanese Yen and repeated natural disasters.
MotoGP added that having an eye to returning to MotoGP in 2014, Suzuki will now focus on developing a competitive new racing machine for that class.
Suzuki will continue motocross racing activity and support of road racing activities using mass-produced motorcycles, by obtaining FIM homologation and co-operation with the supplier of its development racing kit parts.
