Rolon X-Ring Chain & Sprocket Kit NXR 143 – Yamaha FZ16 / FZS / Fazer 150 (R428NXR 128L, 14T/40T, 6-Hole Rear)

If your Yamaha FZ16, FZS or Fazer 150 has started giving chain noise, jerks while accelerating, or visible rust on the sprocket teeth, it’s time to replace the complete drive set – not just the chain. The Rolon KIT NXR 143 is a heavy-duty sealed X-Ring chain & sprocket kit engineered specifically for the first-gen FZ/FZS/Fazer 150 platform.

Built around Rolon’s R428NXR sealed X-ring chain (128 links) with a 14T front and 40T rear sprocket, this kit maintains stock gearing while dramatically improving refinement, life and resistance to Indian dust, rain and city abuse. Multiple fitment sources and Rolon’s own catalog confirm NXR 143 as the heavy-duty upgrade for FZ16/FZS/Fazer 150 carb models – no drilling, no jugaad, just direct fit when your old set is worn out.

Compared to basic open chains or local duplicate kits, the X-ring design holds lubricant longer, reduces metal-to-metal contact and keeps the drivetrain smoother on both daily commutes and highway rides.

Buying from Under The Hood (underthehood.co.in) means you get 100% genuine Rolon stock, expert packing, and support from a real multi-brand service studio that actually installs these kits on customer bikes. Pair it with quality chain cleaner & lube from our Chain Kits & Maintenance and your FZ will feel tight, smooth and ready for the next 20–30,000 km of disciplined riding.

Installation & Maintenance Notes

• Always install the complete kit (chain + both sprockets) together to avoid premature wear.

• Ensure correct chain slack as per Yamaha FZ owner’s manual – typically checked mid-span with bike on side stand.

• After installation, re-torque all sprocket and wheel nuts to factory spec and recheck after the first 100–200 km.

• Clean with a dedicated chain cleaner (not petrol/kerosene) and lube every 500–700 km in city use, or sooner in rain/dust.

• Avoid pressure-washing the chain at close range; it can force water past the X-rings and reduce life.

• For unsure buyers, Under The Hood customers near Varanasi can book professional fitment at our studio; online buyers should go to a trusted mechanic with proper tools and torque wrench.

FAQs (Schema-Ready)

Q1. Will Rolon NXR 143 fit my Yamaha FZ V2 or FZ-X?
A. No. NXR 143 is only for FZ16/FZS/Fazer 150 carb models (V1 platform). FZ/FZS V2, V3 and FZ-X 150 FI use different sprocket sizes and chain lengths; check our listings for HBSXR 228 / NMR F316 instead.

Q2. Is this kit better than the stock/open chain setup?
A. Yes. NXR 143 uses a sealed X-ring R428NXR chain, which typically offers smoother operation, less noise and longer life than basic open chains when cleaned and lubed regularly, while keeping your stock 14T/40T gearing intact.

Q3. How do I confirm this will fit my bike before ordering?
A. Check your existing kit: if your Yamaha FZ16/FZS/Fazer 150 has a 428 chain with 128 links, 14T front sprocket and 40T rear sprocket with 6 mounting holes, NXR 143 is the correct Rolon heavy-duty replacement. You can also cross-check with the Yamaha FZ16 parts list or ask your mechanic.

Q4. Is this original Rolon or a local duplicate?
A. We only sell genuine Rolon kits sourced from authorised distributors, shipped in original branded packaging with KIT NXR 143 markings. Under The Hood is a real service studio + e-commerce store, so we reject loose/duplicate chains and sprockets that don’t meet OEM quality.

Q5. Will this affect my mileage or engine life?
A. With the stock 14T/40T gearing retained, mileage and engine load remain similar to OEM. A new, properly adjusted sealed chain can actually reduce power loss and noise, helping the bike feel smoother and more efficient over long term.
