Vivo is right, Kymco is just covering their ass.
Don't rev it up on the kickstand
. One time I forgot the clutch in my ZX grabs a lot sooner than my Peop. It pushed the kickstand up and almost pulled me over with it
I always fill the fuel tank on the main stand.
I use the kickstand almost always. I did have it fall over in grass once. The kickstand will sink into grass or even hot asphalt. Now if it's in grass or on a slant I put it on the main stand. But if you're on concrete most of the time like me, no worries about using the kickstand.
