Rolon Brass Chain & Sprocket Kit for Royal Enfield Classic 350 (Rear Drum Brake Variant)
The Rolon Brass Chain & Sprocket Kit (Drum) is a matched final-drive replacement kit developed specifically for Royal Enfield Classic 350 motorcycles equipped with a rear drum brake.
This kit includes:
• 1 × Rolon brass-coated drive chain
• 1 × Front sprocket
• 1 × Rear sprocket
All components are manufactured to match the drivetrain geometry used on Classic 350 drum-brake models, including correct pitch, tooth profile, mounting dimensions, and alignment characteristics.
This kit is designed strictly for rear drum brake variants of the Classic 350. It is not interchangeable with disc-brake variants or newer J-platform / Reborn models.
Platform & Brake-Type Specific Fitment
Classic 350 motorcycles have existed across multiple generations and brake configurations. Drivetrain geometry varies between:
• Drum brake variants
• Rear disc brake variants
• J-platform (Reborn) models
Sprocket carrier design, offset spacing, and chain length differ between these configurations.
This Rolon kit is engineered exclusively for Classic 350 motorcycles equipped with a rear drum brake hub.

⚠️ This kit is designed strictly for Classic 350 motorcycles equipped with a rear drum brake. Do not install on disc-brake or J-platform models.
Correct brake-type identification is critical before purchase.
Chain Construction – Brass-Coated Steel
The drive chain supplied in this kit features steel construction with a brass surface coating.
Brass-coated chains are commonly selected for their:
Improved corrosion resistance
Reduced surface oxidation
Enhanced durability in moisture-prone environments
Better resistance to environmental exposure compared to untreated steel chains
The brass layer acts as a protective surface coating over the steel rollers and side plates. It does not change chain pitch or geometry, but it enhances resistance to environmental wear over time.
The chain maintains standard pitch and roller dimensions required for Classic 350 drum-brake drivetrains.
Front & Rear Sprocket Construction
The sprockets included in this kit are manufactured from hardened steel and cut to match the OEM geometry used on Classic 350 drum-brake variants.
Correct sprocket geometry ensures:
Proper chain engagement
Even load distribution across teeth
Reduced localized wear
Stable chain tension behaviour during operation
Sprocket tooth profile and pitch must align precisely with chain dimensions. Mismatched sprockets can accelerate wear and cause uneven drivetrain performance.
This kit maintains OEM-spec mounting compatibility for the Classic 350 drum-brake hub and front sprocket carrier.
Why Replace as a Complete Set
Chain and sprockets wear together as a system. Replacing only one component can result in uneven wear patterns and reduced service life.
This Rolon kit is supplied as a matched drivetrain set to maintain:
Uniform wear characteristics
Correct load distribution
Consistent final-drive performance
Balanced chain tension behaviour
Replacing all components together supports drivetrain longevity and smoother power transfer.
