Questions & Answers

  • What is a spark arrestor?

    By: Austdog31

    The spark arrestor is essentially a screen near the end of the muffler that prevents sparks from leaving the exhaust system. In doing so, it's designed to prevent forest fires. A spark arrestor is required in order to ride your motorcycle on any national forest property and also, in many states that have land open for ORV use.
