There are thousands of them still in daily use in Indonesia , Malaysia, Tailand , and no doubt other SE Asian countries.
Usually as tourist transport but a lot are still used in agriculture & forestry .
We get a few of them down here from time to time imported by some one with no understanding of the market thinking they will make a killing on reselling them .
There used to be an Indonesian BSA Owners Club who regularly sent us down photos & stories about them .
