Your bike is gorgeous, your price seems fair, and I agree with everything said here so far.
I second trying Cycle Trader, and also Craigslist (I Know, I Know!). I've sold bikes via both those sites. You could also post it on Internet BMW Riders (IBMWR) Marketplace, but I never had much luck there - still, you never know what site will get you a buyer, and you only need one!
Winter's around the corner too, especially in Canada, so there's that as well.
Good pics make a huge difference, as does a good description of the bike, options & accessories, ownership & maintenance history. You're selling yourself as well as your bike - what FS ads get YOUR attention when you're looking to buy.
HTH!
