Benefits
- Secure, permanent joint: Solid rivet construction provides a durable connection that matches the strength of the RQ1 chain and resists the high loads of powerful road bikes.
- Optimised for X-ring chains: Works with the low-friction X-ring sealing of the RQ1 series, supporting the chain's balance of reduced drag and long service life.
- High power capability: Suited to chains that are recommended for engines above 150 hp, making it appropriate for large-capacity, high-torque motorcycles.
- Precise fit: Matched to the 525 RQ1 chain profile and dimensions to maintain correct alignment, pitch and load distribution across the drivetrain.
- Reliable under intensive use: Designed for the stresses of fast highway use, trackdays and demanding everyday riding on heavy or high-output machines.
Typical Use Cases
- Installation of a new Tsubaki 525 RQ1 chain that has been shortened to the correct length and needs a permanent, riveted closing link.
- Replacing a worn or damaged original rivet master link on an existing Tsubaki 525 RQ1 X-ring chain.
- Adapting final drive gearing (sprocket changes) where the chain length is adjusted and a new rivet-type pin link is required.
- Workshop use as a spare master link for high-performance road motorcycles running Tsubaki 525 RQ1 chains.
Installation Notes (General Information)
The pin link is intended to be installed with a suitable chain riveting tool that can correctly flare the pin ends to the specified riveting, plate alignment and chain slack adjustment are essential to preserve the designed strength and durability of the RQ1 chain system.
