My local Suzuki dealer was telling me that the klx, crf and wrf 450s are all sent to a company in oz with a contact to make them ADR compliant they are then returned to the manufacturer for distribution to dealers. Suzuki will not commit to contact with this company. This could mean a long wait before a regoed RMX 450z is avalible, although their is a company in Brisbane that has an ADR kit for the Suzuki but would cost over 2 grand making the suzuki one of the most expensive 450s on the market.
