Product overview
The Tsubaki Offroad Chain 520 MXE 130 links (part number 55251520130) is a premium X-ring drive chain from Tsubaki's MXE off-road specifically for demanding enduro and off-road conditions, this 520-pitch, 130-link chain combines high tensile strength, low-friction X-ring sealing and gold-coloured outer plates for durable, consistent power transfer.
Key features
- Off-road MXE series chain engineered for enduro and hard off-road use.
- 520 pitch with 130 links, providing ample length for a wide range of swingarm and sprocket setups.
- X-ring sealed design for reduced friction and extended service life compared with conventional O-ring or non-sealed chains.
- Gold-coloured outer plates for enhanced corrosion resistance and a high-end appearance.
- Developed for demanding, high-torque applications in modern off-road motorcycles.
- Relied on by teams in multi-day enduro events and used by MX teams for training purposes.
- Pre-stretched at the factory to minimise initial elongation after installation.

Typical applications
The Tsubaki MXE 520 130-link chain is intended for off-road motorcycles where durability and smooth power delivery are design targets:
- Enduro motorcycles operating in mud, sand, rocks and variable weather conditions.
- Motocross and cross-country bikes used for intensive training sessions.
- Off-road machines with high-torque four-stroke or two-stroke engines that require a robust 520-pitch drive chain.
- Setups using larger rear sprockets or extended swingarms that benefit from a longer, 130-link base length.
MXE X-ring technology benefits
As part of the MXE series, this chain incorporates Tsubaki's sealed X-ring technology and high-quality materials to optimise performance in harsh conditions.
- Reduced friction: X-ring profile lowers friction between plates and pins, improving efficiency and helping maintain engine response.
- Improved sealing: X-rings help retain lubricant inside the chain while keeping out water, dust and abrasive dirt, which is especially important in enduro riding.
- Longer service life: Superior sealing and high-quality materials support longer wear life compared with non-sealed off-road chains.
- Consistent performance: Factory pre-stretching minimises early elongation, assisting in stable chain tension after initial setup.
Design and construction
- Heavy-duty construction tailored for repeated high-load impacts from off-road riding.
- Gold-coloured plating on the outer plates adds corrosion resistance against moisture and mud.
- Optimised plate and pin design for rigidity under acceleration and braking loads.
- Available within the MXE family in additional link counts for different gearing requirements (this version: 130 links).
Installation and setup notes
The Tsubaki Offroad Chain 520 MXE 130 links is compatible with sprocket sets designed for 520-pitch 130-link length offers flexibility for various front and rear sprocket combinations and is commonly shortened to the exact length required for a given motorcycle and gearing setup by removing links during installation.
