A total of 448 OKAs have been produced in Australia, of which over 350 are believed to still be operational, both at home and abroad.

The remanufactured series is a completely dismantled OKA, then built to a higher minimum standard, improving power and suspension, new body work and finishes.


As opposed to short term maintenance or cosmetic upgrades, the R Series offers a long-term approach for those existing owners looking to refresh the life of their legacy OKAs.
