I agree that every couple of years is OK to change fork oil. The main thing that will cause fork oil to break down is heat. The worst case scenario from the forks' point of view would be a very hot summer day on a very bumpy road. When the oil is forced through the small orifices that accomplish the damping the friction heats the oil up. The higher the ambient temperature, the harder it is for the fork to dissipate the heat.
Stick with the recommended weight of oil. Sportbikes usually use 5WT, check your manual. No matter what a service tech / manager tells you do not put in thicker oil. It simply increases the risk of blowing fork seals.
good luck
