Rolon HXR 427NF Noise Free Chain Sprocket Kit for Triumph Speed 400 & Scrambler 400 X

Rolon Noise Free Chain Sprocket Kit HXR 427NF for Triumph Speed 400 & Scrambler 400 X is a complete final-drive replacement kit for riders who want the correct chain + front sprocket + rear sprocket set instead of mixing separate parts. Your box clearly shows Model: TRIUMPH SPEED400 / SCRAMBLER400, Part No: KIT HXR 427NF, commodity as Chain Sprocket Kit, MRP ₹2581, and box contents of Chain-1N, Front Sprocket-1N, Rear Sprocket-1N.

This is the right kind of kit to buy when the old chain is noisy, stretched, uneven in tension, or when sprocket teeth are worn and hooking. Multiple live seller pages consistently map HXR 427NF to the Triumph Speed 400 and Triumph Scrambler 400 X, and several of them also publish the buyer-useful spec pattern of 15T front sprocket, 43T rear sprocket, and 103-link chain. That makes this listing much more useful than generic “Speed 400 chain kit” pages that leave the buyer guessing.

The box front also highlights this as a Noise Free Kit with a rubber-mounted front sprocket, which is exactly the kind of wording buyers search when they want smoother engagement and less drivetrain harshness. Buy this when you need a complete chain sprocket replacement kit for Triumph Speed 400 or Scrambler 400 X. Do not buy it for other Triumph motorcycles or by engine size alone. Match the code HXR 427NF first.
