Not much... Oil/filter change.. air up the tires, check the valve adjustment if you want.. and the water in the battery if it's been 6 months...
Then,.. ride a bunch more...
...
From here on,.. you can stretch out oil changes and maintenance to 3k intervals...
Oil/filter... check battery water, brake pads, air filter, inspect tires, drain the airbox tube, check the exhaust header bolts for snug, lube sidestand... (you can go 6 to 8k on valve inspection)...
12k... consider a Versy adjuster, and a Raptor pet... maybe replace brake fluid and bleed... lube the cables...
25k... fork oil, and grease steering bearings... and wash the bike...
...
JMHO... not factory recommended schedule...
