The RK 520 Max O-Drive Chain is a premium sealed O-ring drive chain designed for dependable performance on both street and off-road motorcycles. Built by RK in Japan, this 90-link chain combines high tensile strength with durable construction to support demanding riding conditions and long-term service. Its 520 chain size makes it suitable for motorcycles requiring a standard 520 pitch drive chain, while the sealed O-ring design helps retain lubrication and limit the entry of dirt, moisture, and other contaminants.
Manufactured to high Japanese quality standards, the RK 520MAXO-90 delivers a practical balance of performance, durability, and value. It is engineered for consistent power transmission and reliable operation across a range of riding environments, from daily street use to off-road applications. The 90-link configuration may be suitable for original-equipment or modified drivetrains when confirmed against the motorcycle manufacturer’s chain specification and final gearing requirements.
Before installation, verify that your motorcycle requires a 520-size chain and that 90 links provide the appropriate length for the selected front and rear sprockets. Proper fitment may vary by model, year, swingarm position, sprocket combination, and gearing changes. The chain should be installed and serviced according to the motorcycle manufacturer’s recommendations, including correct riveting, tension adjustment, alignment, and lubrication. The manufacturer part number is RK 520MAXO-90, and the vendor part number is also 520MAXO-90.
