You are going to end up paying 2 to 5 time its value without even benign certain to have the proper documentation to register it here and be able to ride it, you still have to pay import charge 70% , 40% luxury tax, 10% PPn, 5% pph, plus handling charge, clearance charge, warehouse charge, delivery charge. Customs will set the price & the bike must have under 100km & under 12months old, with registraton papers from Australia.
If you are bringing in a classic, you are better off dismantling in parts. Engine and chassis being the most difficult and impossible is registration paperwork (STNK & BPKB).
Unless you have diplomatic priviledges.
The big bike clubs sometime do runs to Malaysia and bring back bikes but cannot get legal paperwork (STNK & BPKB).
