Radiator hose size = ?

I'm away from my bike right now and I'd like to know the size of the radiator hose for an S4R (Desmoquattro).  Does anyone know?

Thanks,

Dave.
There are two different diameters.
From the radiator hoses have a 25mm bore.
The hoses from the pump to cylinders and from the cylinders to thermostat have a 20mm bore.

BTW The blue DP set in my pic is for sale.

Thanks Stewart.

I bought a length of pipe to insert into the hose where my inspection plate is rubbing.
