Heres what you do,
Tell the wife that because you love the bussa you dont want to screw it up on the track, and you will need a bike for the "track only". Now go buy any bike you like,
Im thinking GSXR750,00, ZX12, CCM 900, even a 996 will do. Tell her that the total for the bussa parts if you drop it will cost more than a new bike, and she will agree that you need a "track bike". Explain that you need a set of "Z", Vanson, or Bates leathers also for only a couple of grand more. Im sure she will understand. Its only right. Compare it to her buying clothes for herself so she always has "something to wear". You just need "something to ride"
