Genuine Rolon Chain Sprocket Kit for BMW G310R & G310GS – Premium X-Ring Sealed Drivetrain Set (16T Front / 40T Rear | 112 Links | Part No: R520NXR | Kit Ref: NXR 265)

Advanced X-Ring Sealing Technology: Features high-grade elastomeric X-rings that retain internal lubrication long-term, outlasting standard O-ring configurations.

Induction Hardened Sprocket Teeth: Carbon steel rear sprockets undergo advanced heat treatment to stop teeth hooking, chipping, and premature wear under high loads.

Shot-Blasted Fatigue Resistance: Entire kit surfaces are shot-peened to increase surface density, boosting resistance to fatigue cracking and structural stress.

Corrosion-Fighting Zinc Protection: The rear sprocket features a dense zinc surface coating to protect against rust from rainy conditions and water crossings.

Anti-Vibration Machining: Engineered using high-tech position accuracy tooling to keep the drive line perfectly straight, cutting down on noise and footpeg vibrations.

Direct Drop-In OE Fitment: Manufactured with accurate involute mountings and a 6-hole equi-spaced layout to bolt directly onto the stock BMW hub without spacers.

Precision Power Transmission Engineered for Dual-Sport Touring and Street Performance

Riding your premium machine with a stretched, hooked, or non-sealed chain significantly degrades throttle response, kills fuel efficiency, and can cause catastrophic drivetrain failures far from home. The high-torque single-cylinder engine layout used across the BMW 310 platform puts immense stress on the final drive components. When riding through dusty backroads on a G310GS or launching hard from traffic lights on a G310R, open non-sealed chains quickly let mud, rain, and grime enter their internal bearing zones, destroying the factory grease and resulting in harsh vibrations, noise, and power loss.

Our premium BMW G310R G310GS Chain Sprocket Kit by Rolon (Part No. - R520NXR) is a highly engineered, direct OEM-spec upgrade crafted to resolve final drive wear. The centerpiece of this kit is the premium R520NXR solid-bush X-Ring sealed chain. Unlike ordinary chains, its specialized cross-profile X-rings seal factory grease tightly inside the pin-and-bush assembly while blocking out harmful debris. Paired with a precision-machined 16T front sprocket and an induction-hardened 40T carbon steel rear sprocket, this kit ensures perfect tooth engagement. Swapping out your worn stock set with this genuine replacement removes drivetrain slack, dampens chain slap, and delivers smooth, quiet, linear throttle response across highway miles and rough singletracks alike.

How to Maximize the Lifespan of Your New Rolon X-Ring Kit:

Pro DIY Maintenance Tips

Replace Your Wheel Dampers: For the smoothest power delivery, always inspect and replace the rubber wheel cush-dampers inside the rear wheel hub when installing a fresh chain kit. Worn dampers cause jerky acceleration that can stretch a new chain unevenly.

Clean with Care: Clean the chain every 500–600 km using kerosene or a dedicated safe chain cleaner with a soft nylon brush. Never use petrol, thinners, or wire brushes, as these harsh chemicals and metal bristles will tear up the sensitive internal X-ring seals.

Avoid High-Pressure Washing: When washing your motorcycle, do not spray high-pressure water directly at the chain links from close range. The pressure can force water past the rubber seals, trapping moisture inside and causing the links to rust and seize.
