PS Word to the wise...bring only a model that WAS available in Australia. There are many models that never were , and may be hard to "Aussie comply" at this end.
Another mate of mine , a Vietnam Vet , bought a well lovely 2006 Springer from Bartels's HD in Marina Del Rey in LA 5 years ago, Impulse buy ( as always haha...)
Only then did he discover that the model had not been sold in Australia in 2006 and he had MAJOR grief getting it licensed here in WA.
Long story short , he eventually got it licensed in Qld , then brought it back to WA with Qld plates , and got WA plates like any other Qld vehicle , car or bike or whatever.
LOADSA grief though , and best avoided ! the actual HD model designation is important , ie FXSTSSE2 FLSTN FXDWG etc etc
