Rolon O-Ring Chain & Sprocket Kit KIT NOR 301 – TVS Apache RTR 160 4V BS4 (R428NOR 138L, 13T/45T, 4-Hole)

Chain noise, tight spots and jerks while accelerating are classic signs that your Apache RTR 160 4V’s stock chain set is done. Instead of juggling local “duplicate” kits, upgrade straight to Rolon KIT NOR 301 – the OE-application O-Ring chain & sprocket kit developed specifically for the TVS Apache RTR 160 4V BS4. Confirmed in Rolon’s own kit catalogue and price list as the dedicated kit for RTR 160 4V, it uses a R428NOR sealed chain (138 links) matched to a 13-tooth front and 45-tooth rear sprocket (4-hole pattern) for perfect gearing and direct fitment.

The O-Ring design traps factory grease inside the chain and keeps dust and water out, dramatically reducing stretch and rust compared to open chains. Heat-treated sprockets cut down on hooked teeth and premature wear, so your RTR feels tighter, smoother and more eager to rev – whether you’re slicing through city traffic or doing weekend highway runs.

Buying from Under The Hood means you get fresh, genuine Rolon stock (no loose/open kits), careful packing, and real workshop-level advice on chain slack, lubrication and when to change cush-drive dampers. Pair NOR 301 with our chain cleaner & lube combo and your Apache 160 4V BS4 will feel almost new again.

Note: This kit is for Apache RTR 160 4V BS4 only. BS6 4V models use a different Rolon kit (NXR F408). 2-valve RTR 160 uses KIT HBS 152.

Key Features

• Exact Rolon application: KIT NOR 301 – officially listed by Rolon for TVS Apache RTR 160CC 4V.

• Correct OE-style specs: R428NOR sealed chain, 138 links, 13T front, 45T rear, 4-hole rear sprocket – matched to Apache 160 4V BS4 gearing.

• O-Ring sealed technology: High-quality synthetic rubber O-rings retain lubricant and block dust/water, giving far longer life than non-sealed local kits.

• Solid-bush construction: Stronger load distribution and smoother running under hard acceleration, pillion and luggage.

• Heat-treated sprockets: SAE 1045 alloy steel with hardened teeth for improved wear resistance and consistent chain engagement.

• Reduced NVH: Properly matched chain & sprocket combo cuts chain slap, whining and vibration – bike feels more refined at 60–90 km/h cruise.

• Designed for 160cc performance: Rated by Rolon for Apache 160 4V, with strength reserve for spirited riding, occasional touring and aggressive downshifts.

• Direct bolt-on: OE-spec sprocket carrier pattern and front-sprocket spline – no drilling or modification when used on listed models.

• Under The Hood advantage: Genuine kit with GST invoice, secure packaging, WhatsApp support and option to club with chain lube/cleaner & other Apache spares.

Compatibility Table

CHECK PART NUMBER BEFORE ORDERING 

*Year ranges are indicative from model launches; always confirm sprocket tooth count (13/45), 4-hole rear hub and 428 pitch before ordering.

Variants

This listing covers:

• Rolon KIT NOR 301 – Standard O-Ring Steel Kit (R428NOR-138L, 13T/45T, 4-hole rear).

For riders who want visual bling plus extra rust protection, Rolon also offers brass-finish kits for Apache 160 4V like NORC-F322 (Brass chain & sprockets) – ideal for show bikes and detail-oriented builds. These use the same 13/45 gearing but brass-plated plates for a golden look.
(Stock/availability may vary; check Under The Hood’s Apache category.)

What’s in the Box

(From Rolon kit catalog + multiple dealer listings)

• Rolon printed box with QR/maintenance info

• Basic chain care leaflet

Any Under The Hood keychain seen in photos is complimentary and subject to availability – not part of the official Rolon kit.

Installation & Maintenance Notes

• Always replace chain and both sprockets together – mixing new & old parts kills kit life.

• After installation, set chain slack to TVS spec (usually around 25–35 mm mid-span – confirm from your owner’s manual).

• Re-torque front sprocket nut and rear sprocket nuts after the first 100–150 km, then at every service.

• Clean with a soft brush and dedicated chain cleaner (or kerosene); avoid petrol, thinners or high-pressure jets directly on O-rings.

• Lubricate every 500–700 km or after rain/washes using a good chain lube; never ride long with a dry, dusty chain.

• Inspect periodically for tight links, excessive slack, rust or hooked teeth; replace the kit once these appear, even if odometer mileage seems low.

• If your rear hub cush-drive rubbers are badly worn, replace them along with the kit for smoother take-off and less jerk.

FAQs

Q1. Will Rolon KIT NOR 301 fit my Apache RTR 160 4V BS6?
A. Rolon’s catalog and Rolon Premium site list NOR 301 for Apache RTR 160 4V (BS4) and a different kit NXR F408 for BS6 4V. Many dimensions are similar (13T/45T, 138L), but to avoid returns we recommend BS6 owners confirm their OE kit code or tooth count before ordering, or choose the BS6-specific kit.

Q2. How is NOR 301 different from HBS 152 for RTR 160?
A. HBS 152 is for the older 2-valve Apache RTR 160 and uses a shorter 124-link chain with 13/44 gearing. NOR 301 is for the 4-valve RTR 160 and uses a 138-link O-Ring chain with 13/45 gearing. They are not interchangeable – using the wrong kit will upset wheelbase and sprocket alignment.

Q3. Is this better than a normal open chain kit?
A. Yes. NOR 301 uses an O-Ring sealed chain – the rings hold lubricant at the pin-bush area and block contaminants. That means far less stretch, quieter running and much longer life than basic open chains, especially in dusty Indian conditions.

Q4. Will upgrading to this Rolon kit change my bike’s mileage or top speed?
A. No major change. NOR 301 keeps the stock 13/45 tooth combination and 428 pitch, so your final drive ratio remains very close to OE. What you’ll notice is smoother pickup, less chain noise and more consistent performance over time as the chain doesn’t stretch as fast.

Q5. How do I know this is a genuine Rolon kit?
A. Genuine kits have KIT NOR 301 clearly printed on the box, proper Rolon branding, QR/maintenance graphics and come sealed from the factory. Under The Hood supplies only genuine, fresh stock with a GST invoice – we do not sell loose or repacked chains.
