What is the stiffness value of motorcycle chassis of around 200 cc engine capacity segments ? 1

I know it's kind of absurd to ask the industrial guarded secretes but I don't have choices. I have to figure out stiffness parameter ( torsional, lateral and vertical ) of motorcycle's front frame and swing arm. Does anybody know the approximate value of these parameters of 200 cc motorcycles ( if its for dirt bike , it will be very suitable ) ?
