Hi,
Usually, site name is defined during WP install and can be changed from within WP settings.
dashboard > general > site name
If it’s already done, see if your theme has a specific setting for such and change accordingly from there.

There is no any plugin or 3. part app. but title is not good for us.
wp: 4.1.1
bbpress: 2.5.6
Technically you’re on the wrong forum, you have no instance of BuddyPress running only bbPress and they are two different plugins.
You might try any of the Title tag plugins out there such as Yoast WP SEO also look at how your theme is handling the title tag in the header and search the WP codex for any guides on filtering the WP title tag to modify the title strings.
