Match the original kit part number, chain length, rear sprocket and mounting pattern.\u003c\/p\u003e\n\u003ch3\u003eDoes it fit Apache RTR 160 4V BS6?\u003c\/h3\u003e\u003cp\u003eSome BS6\/ride-mode parts records show the 136-link chain reference, but BS6 alone does not establish the entire NF321280 kit. Check the chassis-specific TVS catalogue.\u003c\/p\u003e\n\u003ch3\u003eWhat is the front sprocket tooth count?\u003c\/h3\u003e\u003cp\u003e13 teeth (13T).\u003c\/p\u003e\n\u003ch3\u003eWhat is the rear sprocket tooth count?\u003c\/h3\u003e\u003cp\u003e45 teeth (45T).\u003c\/p\u003e\n\u003ch3\u003eHow many links does the chain have?\u003c\/h3\u003e\u003cp\u003e136 links (136L) in the specified kit.\u003c\/p\u003e\n\u003ch3\u003eIs the rear sprocket PCD 82 mm?\u003c\/h3\u003e\u003cp\u003eYes, the relevant TVS parts catalogue identifies NF321280 with an 82 mm rear sprocket PCD. Other mounting dimensions must also match.\u003c\/p\u003e\n\u003ch3\u003eWhat is the difference between NF321280 and NF321540?\u003c\/h3\u003e\u003cp\u003eBoth are listed with 13T and 45T sprockets and an 82 mm rear PCD; the former uses a 136-link chain and the latter uses 138 links in the cited catalogue.\u003c\/p\u003e\n\u003ch3\u003eCan NF321280 replace N9326260?\u003c\/h3\u003e\u003cp\u003eDo not assume so. A later TVS catalogue specifies N9326260 as 13T\/44T\/138L with an 86 mm rear PCD, which differs from NF321280.\u003c\/p\u003e\n\u003ch3\u003eCan I just shorten a 138-link chain?\u003c\/h3\u003e\u003cp\u003eDo not assume that changing link count makes a different chain kit compatible. Chain type, prescribed wheelbase adjustment, sprocket mounting and other fitment details must match.\u003c\/p\u003e\n\u003ch3\u003eDoes this fit Apache RTR 160 2V?\u003c\/h3\u003e\u003cp\u003eNF321280 is documented as an RTR 160 4V kit. Fitment to RTR 160 2V has not been established.\u003c\/p\u003e\n\u003ch3\u003eDoes this fit Apache RTR 200 4V?\u003c\/h3\u003e\u003cp\u003eNo direct fitment for this SKU is established. The RTR 200 4V uses its own model-appropriate final-drive parts.\u003c\/p\u003e\n\u003ch3\u003eIs this a chain-and-sprocket set or a cam timing-chain kit?\u003c\/h3\u003e\u003cp\u003eIt is a rear-wheel final-drive chain and sprocket set, not an engine timing-chain kit.\u003c\/p\u003e\n\u003ch3\u003eAre the sprockets and chain sold together?\u003c\/h3\u003e\u003cp\u003eYes. The kit is defined by one front sprocket, one rear sprocket and one chain in the relevant catalogue. Check the actual box for the small retaining hardware.\u003c\/p\u003e\n\u003ch3\u003eDoes the kit include mounting bolts and lock washers?\u003c\/h3\u003e\u003cp\u003eDo not assume so. Some catalogue illustrations list a retaining washer; verify the physical box for all small hardware before purchase and installation.\u003c\/p\u003e\n\u003ch3\u003eIs the chain X-ring or O-ring?\u003c\/h3\u003e\u003cp\u003eThe TVS catalogue describes NF111510 as a sealing-ring chain and some kit references call NF321280 an X-ring set. Confirm the actual chain label\/type before making an exact seal-design claim.\u003c\/p\u003e\n\u003ch3\u003eWill this improve mileage or acceleration?\u003c\/h3\u003e\u003cp\u003eNo mileage, power or acceleration improvement is guaranteed. A properly specified replacement restores serviceable drivetrain components after wear is diagnosed.\u003c\/p\u003e\n\u003ch3\u003eCan I install it myself?\u003c\/h3\u003e\u003cp\u003eChain riveting, sprocket fastening, wheel alignment and correct slack are safety-critical. Professional installation using model-specific service instructions is recommended.\u003c\/p\u003e\n\u003ch3\u003eHow do I confirm the right kit if my chain has already been changed?\u003c\/h3\u003e\u003cp\u003eUse the bike chassis\/VIN and TVS parts catalogue, and compare the existing rear carrier and sprocket geometry. An aftermarket previously fitted chain may not reflect the factory specification.\u003c\/p\u003e\n\u003ch3\u003eWhat if my rear sprocket has 44 teeth?\u003c\/h3\u003e\u003cp\u003eNF321280 is a 45T kit. Identify the correct 44T replacement kit for your actual mounting geometry rather than ordering by motorcycle name alone.\u003c\/p\u003e\n\u003ch3\u003eIs this genuine TVS?\u003c\/h3\u003e\u003cp\u003eNF321280 is a TVS spare-parts number. Check the delivered product and TVS packaging for authenticity before fitting.\u003c\/p\u003e\n\u003ch3\u003eDoes the package include wheel or cush rubbers?\u003c\/h3\u003e\u003cp\u003eThe catalogue identifies the chain and both sprockets; rear wheel, carrier and cush rubbers are separate unless your actual retail package explicitly states otherwise.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePart number:\u003c\/strong\u003e NF321280  |  \u003cstrong\u003eModel family:\u003c\/strong\u003e Apache RTR 160 4V, selected versions  |  \u003cstrong\u003eSpecification:\u003c\/strong\u003e 13T \/ 45T \/ 136L \/ rear PCD 82 mm.
