Tsubaki 525 RQ2 X-Ring Road Chain – 128 Links
The Tsubaki 525 RQ2 road chain is a premium X-ring drive chain designed for road motorcycles with engine outputs up to approximately 150 part of Tsubaki’s RQ2 series, it combines low-friction performance with long service life, making it suitable for everyday riding, touring and dynamic street use.
Main Features
- Road-specific 525 pitch X-ring chain with 128 links
- Recommended for motorcycles up to around 150 hp
- Low-friction X-ring sealing for reduced power loss and extended durability
- Pre-stretched during production to minimise initial elongation
- Gold-coloured outer plates for enhanced corrosion resistance and a high-end appearance
- Includes hollow rivet-type master link for secure closure with standard chain tools
- High average tensile strength of approximately 45.1 kN for reliable power transmission

Design and Performance
The RQ2 series is engineered for real-world road riding, where consistent performance, long service intervals and smooth power transfer are equally X-ring sealing profile reduces friction between side plates and rollers compared to conventional O-ring chains, while retaining lubrication inside the chain construction helps maintain high efficiency close to that of non-sealed roller chains, while preserving the longevity associated with sealed designs.
Pre-stretching during manufacture limits the initial elongation that typically occurs in new chains, helping the chain maintain correct adjustment for longer after gold-coloured plates not only provide additional corrosion protection but also visually complement many modern road motorcycles.
Typical Applications
- Middleweight and larger road motorcycles that require a 525 pitch chain
- Street, sport, sport-touring and naked bikes up to around 150 hp
- Replacement chain for worn or stretched OEM 525 sealed chains
- Riders who prioritise low maintenance intervals, long service life and clean power delivery
Installation Notes (General)
- Includes a hollow rivet master link suitable for use with standard rivet-type chain tools
- Requires suitable front and rear sprockets in 525 pitch
- Final chain length on the motorcycle depends on the specific sprocket sizes and model; 128 links provide ample length for many road applications where 525 chains are specified
Maintenance Characteristics
- Sealed X-ring design helps retain lubricant inside the chain joints
- Reduced friction at the sealing surfaces compared to conventional O-ring chains
- Designed to work with modern chain cleaners and chain sprays compatible with X-ring seals
