Yeah, there's advertising a bike and then there's counting out the money from a sale. I'd take time to do some really good photos of the bike, including some detail shots of where they would normally be dirty (provided your's is spotless). Pics of all the accessories nicely laid out including service receipts, manuals, CDs, the little plaque if you've got that too, cover, bike mags with the desmo test in them - you get the idea.
Then once its all done decide when you must sell it by, if its this year you're in the 40s, if its next year you're in the 50s and if there isn't a must sell date add another 5.
When it comes down to it, if you've got the most conclusive advert, the cleanest bike, the nicest pics and the price is on par with what else is out there, or better $1000 dollars cheaper, you'll hoover up all the interested parties first - then at least its your deal to lose.
