Tsubaki Road Chain 525 RQ2 – 122 Links
The Tsubaki 525 RQ2 road chain with 122 links is a premium sealed drive chain designed for real-world road use on motorcycles up to 150 combines low-friction X-ring sealing with robust construction to deliver smooth power transfer, long service life and a refined, gold-finished appearance.
Main Features
- RQ2 road series chain engineered for everyday road riding and touring conditions.
- 525 pitch, 122-link length suitable for many mid- to large-displacement road motorcycles where this specification is required.
- Low-friction X-ring sealing reduces drag compared with conventional O-ring chains while retaining excellent lubrication inside the links.
- Gold-coloured outer plates provide a premium look and enhanced corrosion resistance on exposed areas of the chain.
- Recommended for motorcycles up to 150 HP, offering an optimal balance of strength, durability and weight.
- Pre-stretched at the factory to minimise initial elongation after installation and help maintain more stable chain adjustment.
- Supplied with a hollow rivet master link for secure, permanent connection using standard chain riveting tools.
- Precision-manufactured components with tightly controlled tolerances for high impact resistance, reduced kinking tendency and consistent running.

Construction and Performance
The RQ2 series is developed by Tsubaki as a road-focused chain line that balances cost, weight and -stretching at the factory helps reduce the amount of adjustment required after initial low-friction X-ring design minimises energy loss in the drive line while still providing the long service life associated with sealed chains.
High-precision manufacturing methods, including accurately formed bushings and robustly riveted pins, contribute to excellent impact resistance and resistance to results in consistent engagement with the sprockets and a stable, predictable feel from the final drive.
Typical Use Cases
- Standard and naked road motorcycles requiring a 525-pitch, 122-link sealed drive chain.
- Sport and sport-touring machines operated within the recommended power range.
- Daily commuting, weekend road rides and longer touring use where durability and smooth running are important.
- Riders seeking a gold-finish X-ring chain to complement upgraded sprockets or a refreshed final drive assembly.
