Holy #### man! That is funny, I just went through the same exact ordeal this past month when I sold my SV and bought my used '04 'Busa. I live in Papillion, NE.
For the rest of you guys, you have no idea how expensive it is to plate a bike or car in Nebraska. I paid $3,500 to plate my Navigator and $800 to play my '04 'Busa.
Anyways back to the story. I paid cash for my SV and never titled or registered it. When I sold it I had to get the title in my name and just pay the sales tax, which wasn't that bad considering my trade difference was only $700 and penalties for not paying the sales tax for almost a year was only $5.
Well I did that so I could get the title in my name to sell. I just avoided plating it, which means paying property, wheel, and some other bullshit taxes. So I paid that off, then I plated my new bike, property tax and such wasn't bad, just sales tax killed. In Iowa it costs like $35 to plate a bike.
For a while I thought I wouldn't plate my new 'Busa either, but then I hated getting nervous sitting at stoplights with cops behind me. I never did get pulled over. I did once however for speeding, but just got a warning and I didn't even have plates or a license on my SV at the time.
So all in all, just get it plated and over with. By the way, I'm Sithor on omahasportbikes.com What color 'Busa did you get man?
