Va a finire che su dieci costruite ce ne sono in giro cinquanta... ...ci godrei per quelli che le han pagate più di 100.000 $.

Si.... sarebbe come aver comperato la Fontana di Trevi (vedi Totò e Nino Taranto in Totòtruffa)

Sempre sullo stesso topic postato da Tums....
Se è vero quanto dicono, la persona si sarà già suicidata.

"Hi Ujeni,
thanks for the pictures. This prototype is the same as was talked about (and pictured) on SOHC4 forum in 2007. If I remember it well, some guy had bought it from Honda dealer (his friend) who call him, that somebody came to them and asked them if they want to buy his bike. Maybe he didn´t know what bike he really had. If the previous owner saw this Ebay listing with its price he should gone mad..... Sometimes crazy things happen."

[Attila]

Ciao Ujeni,Grazie per le foto. Questo prototipo è lo stesso poiché era parlato (nella foto) sul forum di SOHC4 nel 2007. Se ricordo bene, un tizio aveva comprato da rivenditore Honda (suo amico) che lo chiamano, che qualcuno è venuto a loro e ha chiesto loro se vogliono comprare la sua moto. Forse egli didn´t sapere quale bici aveva davvero. Se il precedente proprietario ha visto questo Ebay inserzione con il suo prezzo egli dovrebbe impazzito... Accadono cose a volte pazza."

è la terza volta che vedo questo affare...sempre della stessa marca, se guardi le foto dei carbs. i 4 tubi escono dall'affare, sono montati all'immissione sui carbs...nn si vede però se il marchingegno ha pure i tubi in entrata ???
