Tsubaki 530 RQ1 XRG Sigma Road Chain – 102 Links
The Tsubaki 530 RQ1 XRG Sigma 102-link chain is a premium X-ring road chain developed for high-performance for engines producing over 150 hp, it combines outstanding tensile strength, precise manufacturing and reduced friction for demanding street and sport applications.
Main Features
- High-performance RQ1 series – engineered for powerful road bikes with more than 150 hp.
- 530 pitch, 102 links – suitable for motorcycles requiring a 530 chain with 102 links in standard or custom gearing setups.
- X-ring sealing (XRG Sigma) – advanced X-ring design to retain factory-applied lubrication and lower friction compared with standard O-ring chains.
- Gold outer plates – RQ1 variant of the Sigma XRG chain with gold-colored outer plates for a premium look and corrosion resistance.
- High tensile strength – approximately 45.1 kN tensile strength for excellent resistance to stretching under heavy loads.
- Pre-stretched construction – minimizes initial elongation after installation and reduces adjustment intervals.
- Rivet-type master link included – secure connection designed for high-horsepower road use.

Construction and Performance Benefits
- Precision-manufactured components – accurately formed pins, bushings and rollers contribute to smoother engagement with the sprockets and reduced vibration at speed.
- Advanced X-ring seals – the X-shaped cross-section reduces rotational friction, helping to transfer more power to the rear wheel while maintaining long service life.
- High-grade steel materials – provide stability under heavy loads, frequent acceleration and high-speed touring.
- Improved wear resistance – optimized surface treatments and sealing help protect against elongation and sprocket wear over time.
- Quad-staked rivet technology (typical for Tsubaki drive chains) – increases resistance to shear forces on each pin connection.
Typical Use Cases
This Tsubaki 530 RQ1 102-link chain is intended for large-displacement road motorcycles that specify a 530 chain and where a 102-link length is applications include:
- High-performance sport bikes and superbikes tuned for strong acceleration and high top speed.
- Powerful naked bikes and streetfighters that place high dynamic loads on the final drive.
- Sport-touring motorcycles used for long-distance riding, where durability and reduced maintenance are important.
- Heavyweight road machines and custom builds using 530 pitch sprockets with a required chain length of 102 links.
Selection Notes
- The chain must match the motorcycle’s required pitch size (530) and be compatible with the front and rear sprocket tooth profiles.
- Correct chain length (102 links) depends on the specific model, swingarm length, sprocket sizes and any gearing changes.
- Use of a rivet-type master link requires appropriate tools and correct installation for reliable service.
