Is there a minimum weight in MOTOGP?

is it like F1 where they combine the drivers and cars weight or is there only a minimum weight of the bike? anyone know???

:riding minimum requirements on motogp bikes differ depending on engine configuration. if i do recall seeing at one point, it was 320 lbs. minimum for 5 cylinders and over. 310-315lbs. min for 4 cyl. and 305lbs. min for 3 cyl. some bikes have to add weight to meet the min. requirements like video cameras or weights added to the bike somewhere. this is approximate, as from what i recall.:jump
