EXW was designed to handle ATV swingarm movement and increased torque stresses and wears 1.7 times longer when compared to O-ring chains. EXW chains also feature special thermal crack resistant sideplates to protect against thermal cracking. Thermal cracking can result from debris or components impinging the chain’s movement. The impingement causes the chain to quickly heat up and cool down in rapid succession. Over a period of time this thermal exposure can reduce the strength of the chain and/or cause a chain failure. It is vitally important to check your bike after a crash to make sure no debris or bike components are in contact with the chain.
