I got a secondhand '18 BMW G310R and I noticed I need to consistently top up my coolant after every couple of rides just around town.
The level drops steadily but I haven't really spotted any puddles so I'm not sure if there's a constant leak?
Anyone dealt with something similar? How do I inspect any signs of leakage before heading to the shop?
 
first thing to do is just inspect your engine area and underneath your ride. See if you spot any of those coolant puddles or residue.
If you don't see anything obvious, you can grab one of those coolant pressure tester gizmos. see if the pressure drops. If it does, you've probably got a leak somewhere.

Check around the water pump weep hole since that's the common spot for slow leaks on G310s. To add to @RodeoDude you also need to check the hoses, radiator, and thermostat housing.
 
Could be a slow leak from a hose, clamp, or even the water pump weep hole. Sometimes it evaporates before you notice. Check around the radiator, hoses, and pump for crusty residues or moisture after rides. Hope this helps.
