thanks for all the replies everyone!
ive been searching the forums for other threads on bags and i came across this one that ninjay250 posted. they are motortrek bags. im thinking about just getting the tailbag at first to see if that is enough. it holds 23 liters not expanded so im hoping that would be fine.
