Cheers Jalak and welcome to the Forums.
Check the Marketplace section for FS ads, maybe you'll find a bike that suits you being offered there. If you wish to advertise in the Want To Buy Forum, you will have to upgrade your membership. Please see
here for details on how to upgrade. Anywhere outside the Marketplace, we are not really a trading forum.
Have you checked local Craigslist, Ebay etc. already?
