All RK chains are pre-stressed and pre-stretched to ensure equal load distribution and minimal maintenanceThey're made of the highest grade medium carbon alloy steel available, with all components shot-peened and heat-treatedSTANDARD (M) SERIESHeat-treated medium carbon alloy steel constructionAll components heat-treated and shot-peened for maximum strengthTwo-point pin riveting and solid rollersFor motorcycles up to 400cc that did not come with an O-ring or heavy-duty chain as standard equipmentChains include clip connecting linkXSO SERIESPro X-ring chain lasts five to eight times longer than standard chainProvides two more lubricant pools than conventional O-rings for longer lifeLubricated with specially formulated, vacuum-injected U-grease; locked in by tough nitrile butadine rubber X ringsPolished and shot-peened link platesHigh tensile strength ensures reliable performanceCut-to-length and bulk chains include rivet connecting linkGXW/GSV SERIESAdvanced design XW-ring provides better sealing to extend wear life up to 100 percentXW-ring chains are the best high-speed, extreme heat performance chains available todayChains include rivet connecting linkXSOZ1 SERIESLighter and stronger than RK's original X-ring chain, the XSOZ1 allows riders to keep their stock chain size while reducing weight and increasing strengthBy reducing overall material, it's 12% lighter than its predecessorCut-to-length and bulk chains include rivet connecting linkDR SERIESHeavy-duty chain lasts much longer than standard chainDR drag racing chain is among the strongest and lightest in this classFor use on motorcycles that did not come stock with an O-ring chainChains include clip connecting link530 DR - The ultimate lightweight 530 drag racing chainAt just 2,2 kg (4,92 lb) per 100 links, 530 DR weighs less than most 530 O-ring chains and still provides an average tensile strength of 4717 kg (10.400 lb)Pre-stretched and pre-stressed to ensure equal load distributionRK CHAIN ORDER CHARTNOTE: If your motorcycle came factory-equipped with an O-ring chain, it must be replaced with an O-ring chain.
