Not sure about now, but, I have been receiving emails from Zero suggesting purchase of new bodywork to brighten up existing bikes.
Compared to most legacy companies, the Zero body parts are ( were? ) considerably less expensive. A Few years back, I was going to get
the Carbon Fiber locking top that Hollywood Electrics devised but Zero came up with the locking top about the same time and I went with
an OEM part instead. You might check with them, they may have used pieces or, you might wish to go with a whole new set, make it look
like a 2021.
