Rolon KIT HXR 366 Chain & Sprocket Kit – KTM 250 Adventure (BS6) – 520 X-Ring, 14T / 46T, 114L – Heavy Duty Touring Setup

If your KTM 250 Adventure has started feeling jerky, noisy or rough at the rear wheel, your stock chain set is telling you it’s done. The Rolon KIT HXR 366 Chain & Sprocket Kit is a heavy-duty, X-ring sealed upgrade specifically engineered for the KTM 250 Adventure (BS6) – built to handle long highway rides, mild off-road and everyday commuting.

Rolon’s own and leading reseller listings clearly specify HXR-366 for 250 Adventure with a R520 HXR-114-2 sealed X-ring chain, 14T front sprocket and 46T rear sprocket. This keeps the bike on optimal adventure gearing while giving you smoother drive, reduced chain slap and far better life compared to a tired OE or non-sealed chain.

The heavy series solid-bush X-ring chain is designed for high-power motorcycles and all-terrain use – exactly what you ask of a 250 ADV. Induction-hardened sprocket teeth, zinc finish and precise machining mean better load handling, less wear and a quieter drivetrain even when the bike is loaded with luggage and a pillion.

At UnderTheHood.co.in, you get 100% genuine Rolon stock, proper invoice billing, careful packing and rider-to-rider support. We don’t just sell a kit – we also help you with chain maintenance tips, lube recommendations and install guidance, plus related products like chain cleaner, chain lube and sprocket dampers to complete your 250 ADV drivetrain refresh.

Installation & Maintenance Notes

• Always replace chain + both sprockets together to avoid premature wear.

• After installation, set chain slack as per KTM 250 Adventure owner’s manual (check actual range; typically moderate slack for ADV suspension travel).

• Re-check chain tension after the first 100–200 km as new X-ring chains bed in.

• Cleaning:

  • Use kerosene or branded chain cleaner (Motul, Liqui Moly, etc.).

  • Avoid petrol/diesel/harsh degreasers that can damage X-rings.

• Lubrication:

  • Lube every 450–600 km or sooner in rain / off-road conditions with X-ring safe chain lube or SAE 90 gear oil.

• Avoid over-tightening – too little slack can damage output shaft bearing and suspension behaviour.

• If you are not comfortable setting chain slack and wheel alignment, get the kit installed at a trusted KTM service centre or Under The Hood Studio (Varanasi) / your preferred expert mechanic.

FAQs 

Q1. Will Rolon KIT HXR 366 fit my KTM 250 Adventure directly?
A. Yes. Multiple trusted sellers and Rolon’s own product group list KIT HXR 366 specifically for KTM 250 Adventure, with 14T front, 46T rear and a 114-link 520 X-ring chain. No modification is needed if your bike is a stock 250 Adventure.

Q2. Is this kit brass or standard steel?
A. KIT HXR 366 is a heavy-series steel X-ring kit with zinc-coated, induction-hardened sprockets – not a full brass kit. Some sites also sell a separate brass-finish HXRC series kit for KTM 250 ADV—those use different codes (e.g., HXRC 385). We are clearly listing HXR 366 as the steel X-ring version.

Q3. Will this kit change my bike’s performance or mileage?
A. HXR 366 keeps the commonly used 14T / 46T adventure gearing, so character and mileage remain close to stock when installed and maintained correctly. You mainly feel smoother drive, less jerkiness and reduced chain noise versus a worn chain set.

Q4. Is this original Rolon or a local duplicate kit?
A. On UnderTheHood.co.in, you get 100% genuine Rolon products sourced from authorised distributors. Packaging carries the HXR-366 marking, correct sprocket codes and chain code, and you receive a proper GST invoice – no loose or mixed local parts.

Q5. Can I use Rolon HXR 366 on KTM Duke 250 or other bikes?
A. HXR 366 is marketed for 250 Adventure. Some parts sellers mention “Duke 250 Adventure”, but hub pattern and gearing on street Dukes can differ. If you want to try it on Duke 250 or any other bike, you must physically confirm tooth count (14/46), chain length and bolt pattern. Otherwise, choose a Rolon kit specifically listed for your model.
