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.\n\u003cp\u003eThe RK EXCEL GB420MXZ4-120 gold EXW drive chain is designed for ATV and off-road applications that experience swingarm movement and increased torque stress. Compared with standard O-ring chains, EXW technology is engineered to provide up to 1.7 times longer wear life, helping deliver dependable performance during demanding riding conditions.\u003c\/p\u003e\u003cp\u003eThis RK EXCEL chain features specially designed, thermal-crack-resistant side plates that help protect against damage caused by debris or components contacting the chain during operation. Thermal cracking can occur when repeated contact causes the chain to heat and cool rapidly, potentially reducing chain strength over time. Always inspect the motorcycle or ATV after a crash to confirm that no debris or vehicle components are interfering with chain movement. The GB420MXZ4-120 includes a clip-style master link; a rivet-style master link is available separately. This chain is intended for off-road and ATV use and is not recommended for street applications.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eBrand:\u003c\/strong\u003e RK EXCEL\u003cbr\u003e\u003cstrong\u003ePart Number:\u003c\/strong\u003e GB420MXZ4-120\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eTensile strength: 7,700 pounds\u003c\/li\u003e\n\u003cli\u003eMaximum engine rating: 750cc for off-road and ATV applications\u003c\/li\u003e\n\u003cli\u003eChain weight: 3.70 pounds\u003c\/li\u003e\n\u003cli\u003eMaster link included: Clip type; rivet type available separately\u003c\/li\u003e\n\u003cli\u003eMaximum chain width: 22.0 millimeters\u003c\/li\u003e\n\u003cli\u003eNot recommended for street use\u003c\/li\u003e\n\u003cli\u003eEXW design helps withstand ATV swingarm movement and increased torque stress\u003c\/li\u003e\n\u003cli\u003eThermal-crack-resistant side plates help protect against repeated heat and cooling caused by chain contact or debris\u003c\/li\u003e\n\u003c\/ul\u003e\u003cstyle\u003etable.productattributes, .productattributes td { border-bottom: 1px solid #ddd; border-collapse: collapse; padding: 2px; text-align: left; }\u003c\/style\u003e\n\u003ctable class=\"productattributes\"\u003e\n\u003cthead\u003e\u003ctr\u003e\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003cbr\u003e","brand":"RK EXCEL","offers":[{"title":"Default Title","offer_id":67738462290105,"sku":"691-11000G","price":113.95,"currency_code":"USD","in_stock":false}],"url":"https:\/\/www.thespeedshopusa.com\/products\/rk-excel-gb420mxz4-120-gold-420-x-120-exw-atv-and-off-road-drive-chain","provider":"THE SPEED SHOP USA","version":"1.0","type":"link"}
