Rolon HBS 239 Chain & Sprocket Kit – Bajaj V15 / Vikrant 150 DTS-i (428HBS-124, 14T Front, 42T Rear)

If your Bajaj V15 / Vikrant 150 has started making chain noise, feels jerky on take-off or shows hooked sprocket teeth, it’s time for a complete drivetrain refresh. The Rolon HBS 239 chain & sprocket kit is the OE-spec replacement kit engineered specifically for the V15 150cc DTS-i engine.

According to the official Rolon kit catalogue, HBS 239 is configured for Bajaj V15 with a R428HBS heavy-duty 124-link chain, 14-tooth front sprocket and 42-tooth rear sprocket. This matches the original gearing, so you restore smooth stock performance with the bonus of Rolon’s robust HBS series chain construction.

Competitor sellers like Sap Motors and others highlight corrosion-resistant sprockets, induction-hardened teeth and precise fitment for the V15—this kit delivers all of that, plus our deeper fitment detail, install tips and support.

At Under The Hood, you get 100% genuine Rolon stock, carefully packed so sprockets don’t bend in transit. Combine this kit with quality chain cleaner and lube from our Chain Maintenance collection for maximum life. For riders near Varanasi, our studio can install and set correct slack; for others, it’s a direct bolt-on at any competent mechanic.

Choose Rolon HBS 239 to eliminate harsh jerks, reduce vibration and protect your V15’s output shaft and rear hub for thousands of trouble-free kilometres.

Installation & Maintenance Notes

• Always replace chain and both sprockets together to avoid rapid, uneven wear.

• After installation, set chain slack as per Bajaj workshop manual (typically ~25–30 mm vertical movement at mid-span with rider weight).

• Re-check slack after first 200–300 km; then at every service.

• Clean with a proper chain cleaner (avoid petrol/kerosene on sealed chains) and lube every 500–700 km, or sooner in rain or dusty conditions. Rolon recommends SAE 90 oil or equivalent chain lube.

• Avoid pointing a pressure washer directly at the chain and sprocket seals.

• Inspect periodically for tight spots, rust or heavily hooked teeth; replace the kit if any of these appear.

• For best results, also inspect and replace rear hub rubber dampers if worn out when installing the kit.

FAQs (Schema-Ready)

1. Will the Rolon HBS 239 kit fit my Bajaj V15 Power Up 2019 model?
No. Rolon HBS 239 is specified for the original V15 150 DTS-i with 14T/42T gearing. The V15 Power Up 2019 uses a different kit (HBS 297) with a 15T front sprocket. Please choose the correct kit for your variant.

2. Is this kit better than the stock Bajaj chain sprocket set?
Rolon is an OEM-grade supplier and HBS 239 uses a R428HBS heavy-duty chain with hardened sprockets, providing equal or better life than factory kits and significantly better performance than local unbranded sets that wear quickly and can damage the hub or shaft.

3. Will changing to this kit affect my bike’s mileage or top speed?
No. The kit retains the stock 14T front and 42T rear sprocket combination, so your speedometer, acceleration and fuel efficiency remain similar to OEM—just with smoother, quieter drive thanks to fresh components.

4. How often should I replace the chain sprocket kit on a V15?
For a well-maintained V15 ridden in mixed city/highway use, chain kits typically last 20,000–30,000 km. Replace earlier if you notice excessive slack, uneven adjustment, rust, stiff links or sharply hooked sprocket teeth.

5. Is this an original Rolon product or a local duplicate?
Under The Hood only sources genuine Rolon HBS 239 kits from authorised distributors, matching the part code and configuration listed in Rolon’s official catalogues and price lists. We do not sell loose or counterfeit chain sets.

6. Do I need any extra parts to install this kit?
No additional sprockets or chains are required. Your mechanic will reuse the existing nuts/bolts and chain adjusters. We only recommend checking and replacing rear hub dampers or sprocket carrier rubbers if worn.
