Tsubaki Offroad Chain 520 MXC 118 links 55316520118
The Tsubaki Offroad Chain 520 MXC 118 links 55316520118 is a premium, non-sealed motocross drive chain engineered for competition-level off-road use, developed in collaboration with leading MXGP racing teams to deliver maximum power transfer and reliability on the dirt track.
As part of Tsubaki's MXC series, this 520-pitch chain combines lightweight construction with high strength for professional dirt this version, the chain is supplied with 118 links, making it suitable for many off-road motorcycles that require a 520 transmission with a 118-link chain length.
Main features
- Off-road performance chain: Designed specifically for motocross, enduro and trial applications, where rapid acceleration and precise throttle response are essential.
- Non-sealed construction: O-ring/X-ring-free design minimises friction and rotating mass, allowing engine power to be transmitted as efficiently as possible to the rear wheel.
- 118-link 520 setup: Standard 520 pitch with 118 links for wide compatibility with modern off-road motorcycles using 520 final drive systems.
- Developed with MXGP teams: MXC chains are developed together with top European MXGP racing teams to withstand intense race conditions and professional-level loads.
- High-strength construction: High tensile strength and robust components resist shock loads, torsion and the repeated impacts typical of motocross and enduro racing.
- Lightweight, low-drag design: Reduced rotating mass and low internal friction support fast revving and responsive acceleration, especially beneficial on technical tracks.
- Gold-coloured finish: Signature gold outer plates provide a distinctive look and additional surface protection against the elements.

Design advantages
The MXC series focuses on minimum mechanical losses and maximum absence of sealing rings reduces friction between pins, bushings and rollers, resulting in a free-running chain that supports quick acceleration and strong drive out of corners.
At the same time, high-strength materials and careful heat treatment provide the robustness required for jumps, landings and continuous load changes typical in motocross and enduro balance of low weight and high durability makes the 520 MXC 118-link configuration well suited for high-performance off-road drivetrains.
Typical use cases
- Motocross race bikes using a 520-pitch, 118-link chain length.
- Enduro and cross-country machines requiring a lightweight, free-rolling chain for technical terrain.
- Trial and extreme off-road motorcycles where precise throttle control and low rotating mass are beneficial.
- High-performance off-road builds where a non-sealed chain is preferred for reduced drag and quick adjustment.
Position in the Tsubaki range
Within the Tsubaki motorcycle chain line-up, MXC chains occupy the dedicated motocross and dirt racing segment, sitting alongside road-focused and sealed off-road chains in the broader other Tsubaki chains prioritise long-distance durability with sealing technology, the MXC 520 118-link chain prioritises reduced friction and immediate power delivery for competitive off-road use.
