Hello gpdesign93,
The following style will hide the menu:
body.bbpress #masthead .menu-container.menu-hide{display:none;}
body.bbpress .main-wrapper .row-container.row-breadcrumb.row-breadcrumb-light.text-right{display:none;}
body.bbpress .post-title-wrapper{display:none;}
body.bbpress .main-container .row-container .double-top-padding{padding-top:0;}
body.bbpress .menu-wrapper.menu-sticky.no-header{display:none;}
Regards,
Jason
