Is buzzing when you turn on ignition switch? Or when you hit start button? Video clearly shows nothing happens when ignition switch is ON, and only buzzes when start-button is pressed. AND bike in that video cranks engine 2nd-time around. Does yours behave exactly like this?
Problem is low battery. How long did you charge new battery? New battery comes in discharged state and must be charged for 24-hrs too. Could've charged old battery to fix this problem. Buzzing sound is your starter solenoid not getting enough power from battery.
1. measure battery voltage with bike off. What is voltage?
2. Measure battery voltage when pushing start button. What is voltage?
This is beginning, we might need to test wiring, stator and R&R condition. DON'T replace any part until you've tested it and confirmed it's bad by comparing numbers you've measured with manual. Otherwise you can be replacing hundreds of good perfectly-working parts with brand-new perfectly-good parts and nothing changes. Would be cheaper to just buy another bike whenever something goes wrong.
