Tsubaki Road Pin link 520 RQ1 (ST) 55212520016

The Tsubaki Road Pin link 520 RQ1 (ST) is a genuine rivet-type master link engineered specifically for the Tsubaki 520 RQ1 high-performance X-ring road motorcycle chain series.

Key features

Designed for Tsubaki 520 RQ1 X-ring road chains, combining high tensile strength with low-friction sealing for powerful road motorcycles.
ST-type pin link (rivet-style master link) for a permanent, high-strength connection using standard motorcycle chain riveting tools.
Hollow rivet pin design (as used on RQ1 chains) helps simplify flare formation during installation while maintaining full strength when correctly riveted.
Precision-machined pins and link plates matched to the 520 RQ1 chain’s dimensions for accurate alignment, smooth articulation and reduced localized wear.
Corrosion-resistant finish and gold/black appearance to integrate visually and technically with the corresponding RQ1 chain.
Compact spare part ideal for chain assembly, length adjustment or replacing a damaged master link on RQ1 520 road chains.
