Tsubaki Road Chain 525 RQ2 106 links
The Tsubaki 525 RQ2 X-ring motorcycle chain is a premium sealed road chain designed for mid- to high-performance bikes up to 150 hp, combining low-friction efficiency with long service life.
Key features
- Road-focused 525 pitch X-ring drive chain with 106 links, suitable for a wide range of modern street motorcycles.
- Low-friction X-ring sealing reduces drag compared with conventional O-ring chains while maintaining excellent wear and contamination protection.
- Gold-coloured outer plates deliver a clean, high-end appearance together with enhanced corrosion resistance.
- Engineered for motorcycles up to 150 hp, offering an optimal balance of strength, durability and weight for everyday road use.
- Pre-stretched during production to minimise initial elongation and help maintain chain adjustment over time.
- Supplied with a hollow rivet-type master link (pin link) compatible with standard chain riveting tools.

Typical applications
This 525 RQ2 chain length is commonly used as a replacement or upgrade on mid-capacity and larger road motorcycles that use a 525 pitch chain and require around a 106-link length, depending on sprocket sizes and swingarm design.
- Standard replacement for many naked, sport and sport-touring motorcycles originally equipped with a 525 sealed chain.
- Durable option for daily commuting where long service intervals and smooth, quiet power delivery are important.
- Well suited to dynamic road riding on mid- to high-performance machines within the specified power range.
- Can be shortened to match specific gearing and wheelbase requirements by removing links before final installation.
Design and performance
The RQ2 series targets real-world road use with a construction that balances high tensile strength, controlled weight and long-term X-ring seal keeps lubricant inside the pin and bushing area while blocking out dirt and water, helping the chain maintain performance over high mileages with reduced frictional losses compared to conventional sealed designs.
