Fires are costly. Not only in terms of life and limb, but they can (and will) destroy your off-road rig, side-by-side and yes, your dirt bike. Many riders forget the risk of fire during their pursuit of the extreme. We're risk takers so what's one more, right? It's about calculated risks.
Don't stand by helplessly while your bike burns and could potentially start a wildfire. Being prepared is always a good calculation.
