My handbook for the Classic range gives 22psi as cold inflation pressure and does not differentiate by model or tyre size.(section 13.1 page 66)

It can depend upon the tyres you have and how flexible the side walls are/ how sticky the compound but most people run 21/22 psi for normal condtions.
I run 25 Psi with Yokos but they are fairly 'sticky' tyres and I like to have turn in oversteer, so a very hard back end breaking away helps this
