TSUBAKI Chain 520 - 118 (Part No. 55211000118)
The TSUBAKI 520 motorcycle chain with 118 links (55211000118) is a robust, high-precision drive chain designed for modern high-performance for demanding off-road, enduro and street use, it combines strength, wear resistance and stable power transfer in a compact 520-pitch format.
Key Features
- High durability construction – Manufactured from premium steel for excellent tensile strength and long service life under high load.
- Precision-engineered components – Tight manufacturing tolerances support smooth, efficient power transmission and consistent chain tracking.
- Advanced heat treatment – Pins, bushings and rollers undergo controlled heat treatment to reduce elongation and improve fatigue resistance.
- Corrosion-resistant surface – Protective coating enhances resistance to rust and environmental impacts, making the chain suitable for varied weather and riding conditions.
- Stable performance over time – Optimized geometry and surface finish help maintain correct chain tension and reduce the need for frequent adjustment.
- Low-maintenance concept – Designed for long intervals between servicing when maintained according to motorcycle manufacturer recommendations.

Performance and Reliability
This TSUBAKI chain is developed to withstand intensive use where rapid acceleration, hard braking and frequent load changes are optimized interaction between pins, bushings and rollers supports uniform load distribution, helping to minimize localized wear and extend overall chain life.
The corrosion-resistant finish and high-quality base materials make the chain suitable for use in rain, dust and mud, provided that appropriate cleaning and lubrication intervals are stable construction contributes to dependable sprocket engagement and can help reduce noise and vibration in the final drive.
Typical Use Cases
- Motocross and enduro motorcycles using a 520-pitch, 118-link chain (or requiring cutting to length).
- Off-road and dual-sport machines where a durable, high-strength chain is required for mixed terrain riding.
- High-performance street and naked bikes specified for 520 chains and looking for a robust replacement chain.
- General 520 conversion setups on compatible motorcycles, where reduced rotating mass and strong final drive components are desired.
Design Highlights
As a specialist in drive technology, Tsubaki focuses on high manufacturing accuracy, consistent heat treatment and stringent quality 520 × 118 chain reflects this approach by pairing robust base materials with an engineering-led design that targets long-term reliability in demanding motorcycle applications.
The chain is supplied pre-lubricated from production and is intended to be installed and maintained according to motorcycle and workshop best alignment, tension adjustment and lubrication intervals are essential to fully benefit from the chain’s performance potential.
