I also bought my bike in October of 2013. Just did my anti freeze last month, manual says every two years.
You should flush out you brakes also a two year interval, and more important than antifreeze, IMHO.
Brake fluid is hygroscopic, ie it sucks in moisture from the ambient air. Over time, that lowers the temperature at which it boils. Sufficiently contaminated stuff might boil during hard braking, which disables the brakes. So yeah, replace regularly.
