Have you tried switching the template of the forum page to a full width option?
And you could use a plugin to control on which page which widget is shown. Jetpack’s new Widget Visibility module can do that job quite nicely.
I ended up adding a new CSS rule to my theme’s CSS file, luckily bbPress uses a unique class on the page. Adding the following removed the sidebar from my theme, which is based on Genesis:
body.bbpress .sidebar {
display: none ! important;
width: 0px;
}
body.bbpress #content {width: 920px;}
Keep in mind that the content width of 920px is based on my theme’s container and you may need to adjust it to suit your needs.
Here is my installation:

What do you mean with:
“Have you tried switching the template of the forum page to a full width option?”
Where is this “template” ?
For a page you write, you can choose the type of layout you want given that your theme offers that. However, bbPress runs on a page created on the fly, three is no page called “forums” unless you create one and then use shortcodes to bring up the forum.
Every theme has a CSS file which can be edited within WordPress. Go to Appearance/Editor and your theme CSS should load. I edited my theme’s CSS and added the code I gave in my previous post.
