Rolon HPOR 308 High-Performance Chain & Sprocket Kit for Bajaj Avenger 160 ABS – 14T/40T, R520HPOR-112-2

Tired of chain noise, jerks, and uneven power delivery on your Avenger 160 ABS? The Rolon HPOR 308 High-Performance Chain & Sprocket Kit is the direct-fit upgrade designed specifically for your cruiser. Built by Rolon (L.G. Balakrishnan & Bros.), one of India’s leading OEM chain suppliers, this kit combines a sealed high-performance R520HPOR-112-2 chain with a 14T front and 40T rear sprocket for smooth, reliable power transmission.

The sprockets are manufactured from quality carbon steel, induction-hardened for longer life, and finished with anti-rust treatment—ideal for Indian riding conditions, city or highway. The HPOR-series chain is engineered for higher transmission accuracy and reduced noise, helping cut down chain slap and frequent adjustment issues reported with worn stock kits.

At Under The Hood, you’re not just buying a box of parts—you’re buying from riders and technicians who actually install and test these kits. Every Rolon HPOR 308 kit is sourced from authorised channels, carefully packed, and backed by guidance on chain slack, lubrication intervals, and long-term maintenance. Pair this kit with a good chain cleaner and lube from our Chain Maintenance collection to get maximum life and the smoothest possible Avenger 160 ABS ride.

Compatibility Table

*Year range is approximated based on Avenger 160 ABS introduction; always confirm variant name on RC / owner’s manual before ordering.

No other model fitment is listed for HPOR 308 in Rolon’s official sealed-chain kit catalog, so we do not claim compatibility with any other bike.

    No brass / gold or alternative tooth-count variants are associated with HPOR 308; for other Avenger or Pulsar models, different Rolon kit codes apply.

Installation & Maintenance Notes

• Recommended to have the kit installed by a skilled mechanic or at Under The Hood studio for correct alignment and torque.

• After installation, check chain slack as per Bajaj Avenger 160 ABS owner’s manual and re-check after first 200–300 km.

• Clean chain every 2,000–3,000 km or sooner in dusty / rainy conditions using a branded chain cleaner; avoid harsh petrol wash.

• Lubricate every 500–700 km (or after every wet ride) with a quality chain lube from our Chain Maintenance section.

• Always replace chain and both sprockets as a set to avoid premature wear.

• Avoid running an over-tight or bone-dry chain – both drastically reduce kit life and can damage gearbox output shaft bearings.

FAQs 

Q1. Will the Rolon HPOR 308 kit fit my Bajaj Avenger 160 (non-ABS or older Avengers)?
A1. No—HPOR 308 is specifically listed for Avenger 160 ABS only. Older carb Avengers (180/200/220) and Avenger 150 use different Rolon kit codes. Please do not purchase this kit for other Avenger models.

Q2. Does this kit change my bike’s gearing or mileage?
A2. No. The kit uses the same 14T front and 40T rear sprocket combination as OEM, so your overall gear ratio remains stock. You should experience OEM-like mileage and cruising RPM, with smoother transmission thanks to fresh components.

Q3. Is this an original Rolon product or a local duplicate?
A3. This is a genuine Rolon HPOR 308 kit, cross-checked with Rolon’s official catalog and major authorised resellers such as Sap Motors, Riders Junction, SparesCart, and MagicBikers. We source only from authorised channels and bill it properly to avoid counterfeit issues.

Q4. Do I need to change chain adjusters or any other parts while fitting this kit?
A4. In most cases, no—your existing chain adjusters and wheel hardware can be reused if they are in good condition. However, if your adjusters, rubbers, or rear hub dampers are badly worn, we recommend replacing them during the same job for the best result.

Q5. How long will the Rolon HPOR 308 kit last?
A5. Life depends on riding style and maintenance. With proper cleaning, lubrication, and correct chain slack, HPOR-series chain kits can comfortably outlast poorly maintained stock kits. Aggressive riding, overloading, or running the chain dry will shorten life significantly.
