Rolon ORC 329NF Brass O-Ring Chain & Sprocket Kit for Royal Enfield Himalayan 411 – 15T/38T, 525, 110 Links – ORC 329NF

Rolon ORC 329NF is a genuine brass-plated, sealed O-Ring chain + sprocket kit built for the Royal Enfield Himalayan 411.
Confirmed specs: 15T front / 38T rear + 525, 110-link chain (R525ORC-110-1)—ideal when your stock set is stretched, noisy, or jerky.
Packed and shipped by Under The Hood with fitment-support so you don’t end up ordering the wrong pitch/links.

When your Himalayan 411 chain kit is worn, it doesn’t just “make noise”—it creates jerks on throttle on/off, chain lash, uneven pickup, and that familiar “khat-khat” clatter during low-speed riding. The correct fix is replacing the chain and both sprockets together (mixing new + old accelerates wear).

Rolon ORC 329NF is a sealed kit built around a 525 pitch O-Ring chain and matched sprockets in the Himalayan’s stock-style ratio: 15T front + 38T rear, with a 110-link chain (R525ORC-110-1). These exact identifiers are documented in Rolon/LGB’s kit catalogue and repeated by multiple serious sellers—so the fitment is not guesswork.

This ORC kit is widely described as brass plated (inner + outer plates) for improved corrosion resistance and a premium finish—useful for Himalayan owners who ride in rain, dust, slush, or park outdoors.

Buy from Under The Hood for genuine sourcing, clean packing, and rider-first guidance on slack, alignment, and chain care—because installation quality decides how smooth and long-lasting your kit feels.

FAQ 

Q1. Will this ORC 329NF fit my Royal Enfield Himalayan 411?
Yes—Rolon/LGB’s kit catalogue and price list map ORC 329NF to Himalayan 411 with 15/38 and R525ORC-110-1.

Q2. Will this fit Himalayan BS4 vs BS6?
The official catalogue doesn’t publish a strict BS/year cut for this kit code, so verify your existing teeth/pitch/links match 15/38, 525, 110L before ordering.

Q3. Is ORC 329NF an upgrade over stock or same as stock?
It is stock-style gearing (15/38) but positioned as a durability/finish upgrade via sealed O-Ring construction and brass plating (per seller descriptions).

Q4. Is it really brass or just gold colour?
Major sellers explicitly describe both inner and outer plates as brass plated (not paint-only).

Q5. Will this reduce chain noise and jerks?
If your current chain is stretched and sprockets are worn, replacing the full set typically improves smoothness. Results depend on correct alignment, slack, and lubrication.

Q6. How long will it last?
Life varies widely by riding style, load, and maintenance. Regular cleaning/lubing and correct slack are the biggest drivers of longevity.

Q7. Do I need to change cush rubbers with this kit?
If you feel a clunk during throttle on/off, inspect cush rubbers. A new chain kit cannot eliminate slack caused by worn dampers.

Q8. Can I install this at home?
Possible with correct tools and experience, but professional install is recommended for safe chain joining and alignment.
