Rolon HPOR F396 High Performance Brass Chain & Sprocket Kit for Bajaj Pulsar F250 / N250 (R520HPORC 110L / 15T / 44T)

If your Pulsar F250 / N250 chain has started making noise, jerking under acceleration, or showing rust patches, it’s time to upgrade from the stock kit. The Rolon HPOR F396 High Performance Chain & Sprocket Kit is engineered specifically for the Bajaj Pulsar F250 and N250, using Rolon’s R520HPORC brass O-ring chain with 110 links, matched to a 15T front and 44T rear sprocket (6-hole rear pattern).

Rolon is one of India’s most trusted OE and performance chain suppliers, and this kit is designed to handle real Indian riding conditions—daily city traffic, highway runs, pillion + luggage, and spirited weekend rides. The brass-plated O-ring chain improves rust resistance, retains lubrication better, and delivers smoother, quieter drive compared to standard open chains.

Buying from Under The Hood (underthehood.co.in) means you get 100% genuine Rolon stock, carefully packed to avoid transit damage, plus biker-to-biker support if you’re unsure about fitment or installation. This is a direct-fit kit for Pulsar 250 twins—no modifications required when your bike matches the OE 110L / 15T / 44T setup.

Pair this kit with a good chain cleaner and chain lube from our Chain Care range and you’ll extend life, improve throttle response, and get back that tight, confidence-inspiring Pulsar feel.

Installation & Maintenance Notes

• Always install through a trained mechanic or at a trusted workshop to ensure correct alignment and torque of sprocket nuts.

• Set chain free play as per the Bajaj Pulsar F250 / N250 owner’s manual (typically around 25–30 mm of vertical movement at the mid-span) and re-check after the first 100–200 km.

• For sealed (O-ring / brass) chains, Rolon recommends lubricating every ~500 km and cleaning every 2,500–3,000 km, or sooner in dusty / rainy conditions.

• Use only quality chain cleaner and chain lube (no petrol, kerosene, thinner, or high-pressure water jets directly on the chain), and avoid steel wire brushes that can damage O-rings.

• Replace chain and both sprockets together to prevent premature wear of new components.

• After installation, ride gently for the first 50–100 km and re-check chain tension and fasteners.

FAQs 

Q1. Will the Rolon HPOR F396 kit fit my Pulsar F250 / N250?
Yes, this kit is designed specifically for Bajaj Pulsar F250 and N250 models (249cc FI, BS6). As long as your bike uses the OE 15T front / 44T rear sprockets with a 110-link 520 pitch chain and 6-hole rear hub pattern, it is a direct fit. If you’re unsure, WhatsApp us a photo of your existing sprockets before ordering.

Q2. Is this better than the stock Pulsar 250 chain kit?
In most cases, yes. The R520HPORC sealed brass chain offers better rust resistance, smoother operation, and longer service life when maintained correctly compared to typical open or lower-grade chains used on stock kits. That means fewer adjustments, less noise and a more refined ride over time.

Q3. Will this affect my mileage or engine warranty?
A properly installed OE-spec chain & sprocket kit does not negatively impact mileage or engine health. In fact, a clean, well-lubed chain can help maintain mileage and performance. For warranty, this is an OE-spec replacement part from Rolon; however, we always recommend following Bajaj’s service guidelines and keeping your service records up to date.

Q4. Is this original Rolon or a local duplicate?
Under The Hood deals only in 100% genuine Rolon products sourced from authorized distributors and verified price lists. We do not mix sprockets or chains from other brands. You will receive sealed Rolon-branded packaging with proper markings and batch details.

Q5. Do I need any extra parts or modifications to install this kit?
No additional spacers or adapters are needed for standard Pulsar F250 / N250 setups. Just ensure the hub pattern and tooth counts match your existing kit. We recommend replacing worn cush rubbers / dampers at the same time if your rear hub has noticeable play.
