Registration and where you can ride

Registration: Unknown. Check with the distributor and your state authority

No ADR compliance or road registration statement on the AU model page; Kawasaki files it under off-road / KX, not dual-sport.

Registration and permission to ride are separate questions. Where you can ride depends on your state or territory and the land manager. Check with the relevant authority before you ride anywhere.
