TVS Genuine Chain Sprocket Kit for Apache RTR 160 4V – 13T/45T/136L | NF321280

TVS Apache RTR 160 4V Chain & Sprocket Kit – NF321280 (13T / 45T / 136 Links)

Replacing the chain set on your Apache RTR 160 4V? First check which sprocket kit the motorcycle actually uses. TVS lists multiple kits under the same Apache RTR 160 4V model family. NF321280 is the version identified as 13-tooth front sprocket + 45-tooth rear sprocket + 136-link drive chain, with 82 mm rear-sprocket PCD in the relevant parts catalogues.

Do not choose by engine size alone. Some Apache RTR 160 4V applications use NF321540 (13T/45T/138L, 82 mm PCD), while others use N9326260 (13T/44T/138L, 86 mm PCD) in later parts-catalogue references. The sprocket pattern and chain length must be correct for the vehicle.

Quick product specifications

Which Apache RTR 160 4V chain kit do you need?

The comparison follows the relevant TVS RTR 160 4V catalogue revision. Earlier catalogues can differ in chain detail; use the chassis-specific parts reference and the physical kit label as the final check. Do not cut, extend or substitute chains simply to make a different kit appear compatible.

Vehicle fitment — not every RTR 160 4V uses the same kit

There is no reliable all-years answer based on registration year, carburettor/FI, BS norm, number of ABS channels, or whether a motorcycle has ride modes. Changes in factory sprocket and chain specification are possible within a product family. Match the OEM part number or have a qualified TVS parts counter verify the chassis.

What you receive

• One 13T front/engine sprocket for the kit’s specified drivetrain.
• One 45T rear wheel sprocket with the kit’s specified mounting arrangement.
• One 136-link drive chain, listed as a sealing-ring chain in TVS parts references.

A TVS distributor catalogue also depicts a front-sprocket retaining washer with NF321280. Retaining washers, sprocket lock plates, split links, rivet links, bolts, nuts, chain tools and other fittings must not be assumed included until the physical retail kit is inspected. Photos of your actual box contents should be used for final confirmation.

Why replace a worn chain and sprocket set together?

The engine sprocket drives the rear wheel through the chain and rear sprocket. Worn chain pins and rollers, hooked sprocket teeth, seized links or excessive chain elongation can cause uneven drive, vibration, noise or unsafe chain operation. Changing the chain and worn sprockets as a matched set helps avoid new parts running on unevenly worn old components, when replacement is warranted after inspection. No claimed acceleration gain, power increase or guaranteed service-life figure is provided.

Before-order checklist

• Count both sprockets: the correct setup is 13T front and 45T rear.
• Verify rear sprocket attachment: 82 mm PCD is not the entire fitting specification. Match hole count, bore, bolt-circle diameter, offset, and carrier/hub type.
• Check chain length: the required chain is 136 links according to the matching TVS catalogue. Count only using an appropriate chain-counting method.
• Confirm actual chain specification: pitch, width, sealed-ring type and joining method must match the bike and replacement kit.
• Use the exact kit code: NF321280. If the catalogue specifies NF321540 or N9326260, do not order this kit instead.
• Check stock label: verify the part number, printed MRP and actual contents before opening/installation.

Installation and maintenance guidance

• Have a qualified motorcycle technician perform final-drive replacement and alignment.
• Inspect the sprocket carrier, cush-drive rubbers, axle alignment, chain slider, guides and bearings for excessive wear.
• Use the manufacturer-specified retaining hardware, locking method, chain joining process and torque specifications.
• Adjust chain slack at the measurement position and value specified for the exact motorcycle; do not use a generic adjustment figure.
• Inspect the chain after initial use; clean and lubricate as specified for the installed chain. Avoid contaminating brakes or tyres.
• Do not reuse damaged, incorrectly fitted or stretched retaining hardware; do not mix old and new drivetrain parts without inspection.

TVS Genuine identity, OE references and exclusions

NF321280 is a TVS parts-catalogue number. A genuine TVS retail item must be confirmed by the supplied manufacturer-labelled package and correct components; a third-party listing using the code does not independently establish authenticity. The component codes above are catalogue identification references, not proof of universal interchangeability outside this kit.

Not included unless the physical kit expressly confirms otherwise: rear wheel/sprocket carrier, cush rubbers, swingarm chain slider, axle, bearings, chain tools, lubricant or fitting labour. The 13T front and 45T rear are final-drive sprockets; this kit does not contain an engine cam/timing chain.

Frequently asked questions

What is TVS NF321280?

TVS NF321280 is a chain-and-sprocket kit reference for selected Apache RTR 160 4V final-drive configurations, specified as 13T front / 45T rear / 136-link chain in the relevant parts catalogue.

Will NF321280 fit every Apache RTR 160 4V?

No. TVS lists different final-drive kits across the RTR 160 4V family. Match the original kit part number, chain length, rear sprocket and mounting pattern.

Does it fit Apache RTR 160 4V BS6?

Some 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.

What is the front sprocket tooth count?

13 teeth (13T).

What is the rear sprocket tooth count?

45 teeth (45T).

How many links does the chain have?

136 links (136L) in the specified kit.

Is the rear sprocket PCD 82 mm?

Yes, the relevant TVS parts catalogue identifies NF321280 with an 82 mm rear sprocket PCD. Other mounting dimensions must also match.

What is the difference between NF321280 and NF321540?

Both 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.

Can NF321280 replace N9326260?

Do not assume so. A later TVS catalogue specifies N9326260 as 13T/44T/138L with an 86 mm rear PCD, which differs from NF321280.

Can I just shorten a 138-link chain?

Do 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.

Does this fit Apache RTR 160 2V?

NF321280 is documented as an RTR 160 4V kit. Fitment to RTR 160 2V has not been established.

Does this fit Apache RTR 200 4V?

No direct fitment for this SKU is established. The RTR 200 4V uses its own model-appropriate final-drive parts.

Is this a chain-and-sprocket set or a cam timing-chain kit?

It is a rear-wheel final-drive chain and sprocket set, not an engine timing-chain kit.

Are the sprockets and chain sold together?

Yes. 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.

Does the kit include mounting bolts and lock washers?

Do not assume so. Some catalogue illustrations list a retaining washer; verify the physical box for all small hardware before purchase and installation.

Is the chain X-ring or O-ring?

The 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.

Will this improve mileage or acceleration?

No mileage, power or acceleration improvement is guaranteed. A properly specified replacement restores serviceable drivetrain components after wear is diagnosed.

Can I install it myself?

Chain riveting, sprocket fastening, wheel alignment and correct slack are safety-critical. Professional installation using model-specific service instructions is recommended.

How do I confirm the right kit if my chain has already been changed?

Use 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.

What if my rear sprocket has 44 teeth?

NF321280 is a 45T kit. Identify the correct 44T replacement kit for your actual mounting geometry rather than ordering by motorcycle name alone.

Is this genuine TVS?

NF321280 is a TVS spare-parts number. Check the delivered product and TVS packaging for authenticity before fitting.

Does the package include wheel or cush rubbers?

The catalogue identifies the chain and both sprockets; rear wheel, carrier and cush rubbers are separate unless your actual retail package explicitly states otherwise.

Part number: NF321280  |  Model family: Apache RTR 160 4V, selected versions  |  Specification: 13T / 45T / 136L / rear PCD 82 mm. Verify all four before ordering.
