This screen-type spark arrestor is designed to help keep our trails safe! Easy to install, the Barkers Spark Arrestor will eliminate any emission of flammable debris. Many jurisdictions worldwide require the use of a spark arrestor. If you are riding in the United States, and riding on federally managed land, chances are you will need to have a certified and properly maintained spark arrestor installed at all times. This might also be the case if you are riding on state or local land as well, so it is always best to check prior to heading out on the trails.
