Since we are apparently giving advice for the entire world, based only on our local laws, I can advise you from personal experience, that.
ABS braking isn't required on motorcycles, it's optional.
Motorcycles are NOT required to be inspected, not for safety, not for emissions, not at all, ever.
There's lots of info from folks who have removed ABS systems on various vehicles available on the internet. In some cases, it's as simple as unplugging the controller. Do a search starting with the words "removing ABS..". Find info. Even step by step U-tube videos, on removing ABS from a BWM motorcycle.
I've discarded about 25lbs of unwanted factory components from my daily driver, a 20+ year old Plymouth. I'm a Mopar man now.
