What is a common sign of inadequate maintenance on an ATV?

A common sign of inadequate maintenance on an ATV is the presence of unusual noises during operation. This can indicate a range of potential problems, such as worn-out parts, insufficient lubrication, or misalignment, all of which can significantly compromise the vehicle's performance and safety. When an ATV is properly maintained, it should operate smoothly and quietly, without any strange sounds. Unusual noises serve as a warning sign that something may be amiss and needs to be addressed to avoid further damage or breakdown while riding.

In contrast, a smoothly running engine and consistent tire performance are indicators of good maintenance, while regularly checking oil levels is part of routine upkeep rather than a sign of neglect.
