Tsubaki Road Chain 525 RQ2 – 104 Links
The Tsubaki Road Chain 525 RQ2 is a premium X-ring sealed drive chain engineered for real-world road use on motorcycles up to 150 hp, balancing strength, efficiency and long service life.
Key Features
- 525 pitch, 104-link configuration for motorcycles that require this chain size.
- X-ring sealing for reduced friction and improved durability compared with standard O-ring or non-sealed chains.
- Factory pre-stretched to minimize initial elongation after installation.
- Gold-coloured outer plates for enhanced corrosion resistance and a clean, high-end appearance.
- Includes hollow rivet-type master link for secure assembly with standard chain riveting tools.
- Suitable for powerful middleweight and larger road bikes within the recommended power range.

Design & Performance
The RQ2 series is designed as a durable road chain that combines low-friction running with extended service life for everyday riding and sport use.
Its X-ring seal profile reduces drag between the rollers and side plates while keeping lubricant inside the chain, bringing efficiency close to a standard non-sealed chain yet retaining the longevity associated with sealed designs.
High-quality materials and precise manufacturing deliver a strong, stable chain with a high tensile strength rating, supporting consistent power transfer and reliable performance over time.
Typical Use Cases
- Replacement drive chain for motorcycles that originally specify a 525-pitch, 104-link chain.
- Ideal for naked, sport and sport-touring road motorcycles used for commuting and weekend rides.
- Well suited to riders who prioritise low maintenance requirements and long chain life.
- Appropriate for machines within the stated power range that operate primarily on paved roads.
Actual fitment depends on the motorcycle’s original chain pitch, sprocket tooth counts and required link length; only motorcycles specifying a 525 chain in a 104-link configuration are suitable for this chain.
