It is entirely possible that the people that own that shop really believe that there is a CFTA with ASEAN that will allow them to import bikes from Thailand at wholesale prices in Thailand. They would be waiting for an event not scheduled to occur, they would be misinformed and are actually advertising that they are.


If they get your deposit you would be waiting with them….


If they can get one new, it would cost allot more and if not it would have to have been smuggled in. Suzuki formally/legitimately imports only two models, they import those through Jinan Qingqi Suzuki.

The GSX1300R and the M109R are legitimate and dealers selling them are buying them through formal channels established in China. The duty on those are actually less then the 250 would be, however they would have a higher consumption tax rate.
Import of Motorcycles over 970cc from Japan to China have an import duty rate of 30% and VAT rate of 17% and a Consumption Tax rate of 10%
