Rolon CSB Kit F41 Chain & Sprocket Kit – Hero Splendor Y2K / Splendor Plus (428, 106L, 14T–43T)

If your Splendor or Splendor Plus has started making khat-khat noises, needs frequent chain adjustment or feels jerky while accelerating, it’s time for a fresh drivetrain. The Rolon CSB Kit F41 is the correct 428-pitch chain & sprocket kit (106 links, 14T front, 43T rear) engineered specifically for Hero Splendor Y2K and Splendor Plus carb models.

Rolon’s catalog and price list clearly list CSB Kit F41 / F41 SG for “SPLENDOR (Y2K) / SPLENDOR PLUS”, so you’re not guessing fitment. The kit uses a R428MCS-106-1 solid-bush chain and matched sprockets, giving better alignment, less noise and longer life than local unbranded sets.

Where most online sellers only write “Splendor chain set”, this listing tells you exactly what you’re buying: 106-link 428 chain, 14/43 gearing, genuine Rolon packaging, and direct fit on Splendor Y2K / Splendor Plus. That means fewer returns and a smoother, safer commute.

From Under The Hood, you also get workshop-backed support: we fit these kits daily on customer bikes, pack them carefully, and can guide you on proper chain adjustment and maintenance. Pair this kit with our chain cleaner & lube bundle to keep your Splendor worry-free for thousands of kilometres.

Installation & Maintenance Notes

• Always install using a trained mechanic; replace chain and both sprockets together for best life.

• Set chain slack as per Hero Splendor owner’s manual (typically around 20–30 mm vertical play at mid-span with no rider).

• Re-check tension after the first 200–300 km – new chains bed in and may need a slight adjustment.

• Clean using kerosene or a dedicated chain cleaner and a soft brush; avoid petrol, diesel or hard wire brushes that damage O-ring or bush surfaces.

• Lubricate every 500–700 km or sooner if you ride in rain, mud or dusty conditions.

• Never over-tighten the chain – too tight will damage sprocket teeth, swingarm bushes and gearbox output shaft over time.

FAQs (Schema-ready)

Q1. Will Rolon CSB Kit F41 fit my Hero Splendor Plus 2010 model?
A: Yes, if your bike is the carburetted Splendor Plus (97.2cc, chain-drive, non-iSmart). Rolon catalog and multiple dealers list CSB Kit F41/F41 SG as the chain kit for Splendor Y2K / Splendor Plus.

Q2. Is F41 better than a local chain set from the market?
A: Absolutely. Rolon is a well-known OEM supplier. The F41 kit uses correct 428-pitch, 106-link chain and precise 14/43 sprockets, giving smoother power delivery, less noise and longer life than most generic kits when properly maintained.

Q3. Will this kit change my Splendor’s mileage or pickup?
A: No, because it uses the same 14T front / 43T rear gearing as stock. You may feel smoother pickup and slightly better mileage if your old kit was badly worn or dragging.

Q4. How do I confirm if I have Splendor Y2K or some other model?
A: Splendor Y2K / Splendor Plus use the 97.2cc horizontal engine with boxy tank and rectangular headlamp. If your RC says “Splendor+ / Splendor Plus” and your old sprocket has 43 teeth, this F41 kit is the correct choice. If the RC says Splendor Pro, iSmart, Super Splendor etc., you need a different kit – message us for help.

Q5. Is this a genuine Rolon product or duplicate?
A: We only sell genuine Rolon kits from authorised distributors. The box will have Rolon branding, CSB Kit F41 code and printed MRP. We do not deal in loose or re-packed chain sets.
