Your 2004 Yamaha Big Bear 400 isn't about being the fastest ATV in the world, or having the biggest engine, but it is a fantastic all-rounder that is equally at home on the trails as it is hauling stuff around your yard. Treat your old Big Bear well and there's no reason why it shouldn't run like new for another fifteen or twenty years.
There's no secret to looking after an older ATV. All you need to do is service it regularly and always use OEM parts when replacing worn and broken components. OEM parts bring Yamaha's reliability and build quality to the table, which aftermarket parts can't guarantee.
