I ve brought over 15 or so bikes and never had issues, customs and duty is a crock of shit and an out and out money grab, and the shippers are too scared to make waves incase there shit get red flagged. Its all a dock yard scam.
The only time i got jagged is the last motor i brought in was in a box, what i didnt realise when the guys said ill build a crate and screw it in , was he did just that, went to the hardware store and built it in, 4 month later when i still hadnt seen it, had to do a bit of detective work and found my $2K motor sitting in the back of a queensland warehouse and had been for months, complaints flew back and forth, when noone had picked up customs didnt like the wooden crate and had pulled it out and burnt it, no one picked up the label was on it so it and a pair of shocks ended up in the corner as unknown.
Something also tells me, its who is bringing it in not so much as what they are bringing in. IM guessing its one of those industries where the long timers look after each other.
