Ah topic views, that points me in the right direction thanks. For reference then if anyone needs it that means you can do stuff like this:

add_action('bbp_register_views', 'view_popular_topics');

function view_popular_topics() {

bbp_register_view('popular-topics', __('Popular Topics'), array('meta_key' => '_bbp_reply_count', 'orderby' => 'meta_value_num'), false );

}

Then link to the view with:

<a href="<?php bbp_view_url('popular-topics'); ?>"><?php bbp_view_title('popular-topics'); ?></a>

There’s a couple of informative posts re this here:
