Did you not get an owners manual with your bike?
It's all spelled out in there.
Mine's @ home and I'm not, but off-the cuff, in MILES:
Daily - Tire pressure, tread wear, leaks, lights, general condition
600 - Initial service - oil & filter change, valve adjustment check, check everything for tightness, check chain & sprockets (adjust if req'd).
Every 3,000 - Same as above, less valve check, plus check air filter and replace if needed. (Actually, the book says the oil filter only needs to be changed every-other oil change, but most of us change it every time.)
Every 7,500 - Check valves for adjustment. Realistically, the valve adjustment almost never moves after the 7,500 mile mark, so some people may stretch this out if after the 15K check they're unchanged. (I do mine annually and put ~10K miles a year on the bike.)
Every 2 years - change the fluid in the brake & clutch reserviors. Change fork oil. Suzuki says change the rubber hydraulic hoses every 2 years, too - but I don't know anyone who does that. If you do, you should replace with stainless braided lines so you can forget about the rubber hoses.
There's a schedule for the swingarm, suspension, steering head bearings to be inspected, replaced if needed & lubed - but I don't remember that one from the book.
