Indeed, two pages and only one answer to the question, not an entirely correct answer however.
Ilegally imported bikes have been imported as spare parts and scrap metal not as a complete motorcycle and therefore cannot be submitted for testing. There are no doubt tricks that can be used to make this bike legal if you know the right shady people.
Legally imported bikes are advertised as such and can be submitted for testing. Imported bikes come in different flavours too. The import duty is 40 or 50% of declared value but much less if it is imported as personal property, I have heard of a guy going to Italy (where he is a resident) and buying his bike then registering it there and then importing it, I do not know what duty he paid, however, if you buy this bike from him then you will need to pay the remaining import duty.
The test costs 80K and takes a minimum of 6months. Passing the inspection can be a nightmare and many bikes do not pass the emissions requirements alone which are pretty severe in Taiwan. I have heard of a guy spending tons of cash on modifying his bike to pass the inspection. Again if you can make the right contacts they can assist you in passing as they know the tricks to doing it.
Omero seems to have forgotten that he was standing next to me at WRS when we were told very specifically that the Fuel injection requirement will only be applied at the end of the year, so there is still a window of opportunity to test your bike.
My advice is do what makes you happy dude, but if you want to go this route then find people that can help you, make friends with a bike importer.
My personal feeling is that the cost/benefit ratio of a new superbike is bollocks, the second hand prices are so low and the performance since '94 was so high that I dont need a brand new one, in 2000 I bought a '94 Gsxr1100 with a full Yoshi system, dynojetted with the intake de-restricted and race air filter for 1200GBP and was kicking the cr4p out of brand new Gsxr1000’s and Aprilia Rsv’s that cost like 8 to 12 times the price.
In the meantime those expensive new bikes have dropped their value severely while my old bike still holds its value and in fact when i sold my bike I made a profit.
