Tsubaki Road Chain 525 RQ2 – 124 Links
The Tsubaki 525 RQ2 road chain is a premium sealed X-ring drive chain designed for real-world performance on mid- to high-power road 124 links, 525 pitch and gold outer plates, it combines low-friction power transfer with long service life for machines up to 150 HP.
Main Features
- RQ2 road series: Engineered for road use as part of Tsubaki's RQ2 line, developed for motorcycles up to 150 HP, balancing durability, weight and cost.
- Sealed X-ring construction: Uses a very thin X-profile sealing ring that reduces friction between rollers and side plates while retaining internal lubrication, offering efficiency close to a non-sealed chain with the longevity of a traditional O-ring chain.
- 525 pitch road chain: Standard 525 chain size (5/8" pitch, 5/16" inner width) suitable for many naked, sport, sport-touring and adventure motorcycles originally equipped with a 525 sealed chain.
- Gold-coloured outer plates: Corrosion‑resistant gold finish on the link plates for an upgraded appearance and easier visual inspection of lubrication and contamination.
- High tensile strength: Average tensile strength around 45.1 kN provides robust performance and resistance to shock loads in demanding road use.
- Pre‑stretched at the factory: Supplied pre‑stretched to minimise initial elongation after installation and reduce the amount of early adjustment required.
- Hollow rivet master link: Delivered with a hollow rivet (rivet‑type) connecting link, compatible with common chain riveting tools; a clip‑type link is available separately in the RQ2 series when required.
- Versatile length: 124-link length suitable for a wide range of applications where a 525 pitch chain is specified; excess links can be removed during installation if necessary.
