From some googling it has a 7% expansion rate.

Correct me if Im wrong

If 250r has 1500ml (GPZ250R?) coolant and expansion rate is 7%

1500 x 0.07 = 105

Therefore, the capacity of the exansion tank must be at least 105ml, say 150ml.

In the end, you only need a expansion tank not a overflow tank, something the size of a juice box should do, thus eleveating the need for a large tank.

Well thats the theory anyways, practical?????
