Description
The Rolon Brass Chain & Sprocket Kit (HPORC 389) is an OEM-plus drivetrain replacement engineered specifically for Royal Enfield’s J-series 350cc platform. Manufactured by L.G. Balakrishnan & Bros (Rolon), this complete kit replaces worn-out factory drivetrains prone to chain lash and rapid elongation with a heavy-duty, brass-plated O-ring sealed chain paired with precision induction-hardened sprockets.
Key Performance Features
-
Dual-Plated Brass Protection: Inner and outer link plates undergo advanced electro-brass plating, providing superior defense against road moisture, grime, and cosmetic rust while adding a lustrous gold finish.
-
O-Ring Sealed Internal Lubrication: Factory-sealed O-rings lock lubricant inside the pin-bushing interface and seal out road dirt, ensuring quiet running and significantly prolonging service life.
-
NVH & Vibration Damping: Precision-machined front sprocket (with rubber bonding on select batches) and an OE-spec rear sprocket eliminate drivetrain “khat-khat” slap and reduce jerky low-RPM throttle transitions.
-
Induction-Hardened Rear Sprocket: Built with premium carbon steel and heat-treated teeth to resist hooking, even under continuous heavy touring loads and two-up riding.
-
True Drop-In Fitment: Matches factory 15T/42T gearing ratios and 104-link length, requiring zero alterations to chain guards or swingarm adjusters.
