Want to sell my bike - can I post a link to my add here?

I want to sell my '06 Fazer and have an add on Gumtree. Being in Wiltshire I wanted to post the add on this forum as well, but don't know if this is allowed?
I searched the forum rules but couldn't find anything.

Could one of the moderators tell me if this is allowed? Thanks.

post it in the bike for sale category

Can you post a link to it? I can't find the category.
Edit: Found it. Under Classifieds! Thanks.
