The RCB 428H O-Ring Series Chain (132L) in Black/Gold is a heavy-duty, high-performance drive chain that combines extreme durability with a premium “two-tone” aesthetic. The “H” in the 428H designation stands for Heavy-Duty, indicating thicker side plates and reinforced pins compared to standard 428 chains.
This chain is specifically engineered for high-torque 150cc–200cc motorcycles that undergo heavy daily use, touring, or aggressive street riding.
Key Features
-
Heavy-Duty (428H) Construction: Features reinforced inner and outer plates that provide superior tensile strength. This makes the chain highly resistant to “snapping” or stretching under the sudden power surges of a high-compression or modified engine.
-
O-Ring Sealed Lubrication: High-quality rubber O-rings are factory-installed between the chain plates to lock in specialized grease. This internal lubrication prevents metal-on-metal wear at the pin-bushing junction, significantly extending the life of the chain.
-
Premium Black & Gold Finish: The outer plates are finished in a sleek, corrosion-resistant Black, while the inner links and pins feature a high-gloss Gold coating. This creates a striking visual contrast that elevates the look of your motorcycle’s drivetrain.
-
132L Universal Length: With 132 links, this chain is long enough to fit almost any modern bike, including the Yamaha R15, MT-15, Honda CBR150R, and Suzuki GSX-R150, even with larger aftermarket rear sprockets.
-
Shock & Noise Reduction: The O-rings act as a cushion, dampening the vibration and “clinking” noise common in non-sealed chains, leading to a much smoother and quieter ride.

Why Choose the 428H O-Ring Series?
-
Strength for Modifications: If you have installed a UMA Racing Big Bore kit or a performance exhaust, your engine is putting more stress on the drivetrain. The 428H is built to handle that extra load without premature elongation.
-
Aesthetic Customization: The Black/Gold colorway is a “pro-build” favorite. It provides a stealthy yet high-end look that complements almost any bike color, from Matte Black to Racing Blue.
-
Maximum Reliability: For riders who commute long distances or go on cross-country tours, the O-ring seal ensures that the chain remains lubricated internally, even if you are forced to ride through heavy rain for hours.
Installation & Maintenance Tip
When installing the 132L chain, you will likely need to use a chain breaker tool to trim it to your bike’s specific length (e.g., 128L for R15 V3 or 124L for GSX-R150). Maintenance is key: Always use a dedicated O-ring safe chain wax or lube. Never clean this chain with petrol or a wire brush, as you will tear the rubber O-rings and allow the internal grease to escape, leading to rapid chain failure.
