Since track riders don't do race starts, the oil filters don't clog up quite as fast as they do for racers, but the oil breaks down very quickly when you're living on the redline all the time.
It's really a question of how big your budget is and how environmentally sensitive you want to be. Full factory teams change pretty much everything after every single race, and I'm not just talking about fluids and filters, if you know what I mean.
Assuming a reasonable budget, and a reasonable amount of tree-hugger conscientiousness, I would recommend you change out full synthetic oil every three weekends. If you don't use synthetic oil, more like every weekend or two, depending on how hard you ride.
How you use the clutch is a good indicator for how often you change the oil filter, since slipper clutches and people who don't blip the throttle while downshifting burns a lot more clutch material, which of course, ends up in the oil filter.
Suspension oil, at least once a season. Off season is a great opportunity. Always with new fork seals.
520 chains should get replaced every season on a liter bike, maybe every other on a 600, but a fresh chain is cheap insurance against a potentially disastrous crash.
Full system coolant/water flush every off season.
Brake fluid, a full fluid change at least once a season, and I bleed my brakes a lot during the season.
New tires as often as you can, because there's nothing like the feeling (and the safety) of fresh rubber.
I'm so glad the season is finally upon us! It's time to have some fun.
