Oil leaking from rear hub

i left my scoot on the side stand for a few minute and notice oil leaking out of the rear hub... why would this happen is there to much gear oil in the case? its a brand new px200 motor. 

your rear hub oil seal is gone. Leaking oil from rear hub = rear brakes that don't work. Better get it fixed asap

Hi dude
