Rolon HPOR 219 High-Performance O-Ring Chain & Sprocket Kit – Bajaj Avenger 220 Street / Cruise (R520HPOR-110-2, 14T / 36T, 110L)

Give your Avenger 220 Street or Cruise a fresh, tighter and smoother drivetrain with the genuine Rolon HPOR 219 High-Performance O-Ring Chain & Sprocket Kit. This is Rolon’s premium R520HPOR-110-2 O-ring solid-bush chain matched with OE-spec 14T front and 36T rear sprockets – the exact gearing designed for the Avenger 220 Street / 220 Cruise.

Stock, worn-out kits often cause chain noise, jerks, uneven power delivery and accelerated sprocket wear. HPOR 219 solves this with a sealed O-ring chain that holds lubricant inside the pins, resists stretch and rust, and runs significantly quieter than local or non-sealed chains.

Whether you cruise the highway with a pillion and luggage or commute daily through city traffic, this kit is built to handle real-world Indian riding conditions. Sprockets are induction-hardened and zinc-coated for long life, while the 520-pitch chain keeps power delivery smooth across the rev range.

Buying from Under The Hood (Varanasi) means you get 100% genuine Rolon stock, carefully packed, with real biker support on WhatsApp if you’re unsure about fitment or installation. Pair this kit with a good chain cleaner and lube from our maintenance range for maximum life.

Variants

This listing is for the standard silver HPOR 219 O-ring kit for Avenger 220 Street / Cruise.

• Riders wanting a budget OE-replacement can consider Rolon BSOR 173 (standard O-ring kit) instead of this high-performance HPOR series.

• Riders with Avenger 160 or other Pulsar models should look for their specific HPOR / NOR / BSOR kit code – this HPOR 219 is only for Avenger 220 Street / Cruise.

Installation & Maintenance Notes

• Always install using a qualified mechanic with proper chain tools and torque settings.

• Verify your existing gearing (14T / 36T, 6-hole rear hub) before replacing.

• After installation, set chain slack as per Bajaj Avenger owner’s manual and re-check after the first 100–200 km.

• Clean the chain with kerosene or a dedicated chain cleaner – avoid petrol, diesel or harsh solvents.

• Lubricate every 500–700 km in normal use, or sooner in rain / off-road conditions.

• Avoid running a dry or over-tight chain – both drastically reduce kit life and can damage wheel bearings and gearbox output splines.

• For best results, replace the kit as a set (chain + both sprockets together); do not mix new chain with old sprockets.

FAQs

Q1. Will Rolon HPOR 219 fit my Avenger 220 Cruise?
A. Yes. HPOR 219 is catalogued specifically for Bajaj Avenger 220 Street and Avenger 220 Cruise and uses the correct 14T / 36T sprocket set with 110-link 520 HPOR chain.

Q2. What’s the difference between HPOR 219 and BSOR 173 for Avenger 220?
A. Both are genuine Rolon kits for Avenger 220. HPOR 219 uses Rolon’s premium R520HPOR O-ring chain, offering better wear resistance, smoother operation and longer life. BSOR 173 is a standard O-ring kit tuned more for value than outright longevity.

Q3. Is this kit better than the stock Bajaj chain set?
A. In most cases yes. HPOR series chains are engineered as premium O-ring replacements, with improved sealing, anti-corrosion treatment and hardened sprockets, giving smoother power delivery and longer service life when maintained properly.

Q4. Will this affect my bike’s mileage or top speed?
A. Gearing (14 / 36) remains stock, so mileage and top speed stay similar. A fresh, correctly-lubed O-ring chain can actually reduce losses and restore lost performance, especially if your old chain was stretched or binding.

Q5. How do I know if it’s a genuine Rolon kit?
A. Check for the Rolon hologram, printed HPOR 219 kit code and R520HPOR-110-2 chain marking on the packaging/chain. Buying from Under The Hood guarantees sourcing from Rolon’s official distribution with proper GST billing and traceable invoices.
