Aside from the obvious answer that they are required by law.
I think I read somewhere a while back that the USFS rule requiring the use of spark arrestors was rooted in ancient history, going back to steam locomotive days. Anybody know if there's any truth to that?
I know for sure my two stroke doesn't throw embers like a Great Pacific Iron Horse. Is there even a documented instance of a forest fire ever being started by a dirt bike or quad exhaust?
Just wondering, and though this great collection of technically minded soap boxers might have a thing or two to add.
