Construction and Performance
The 428 MXC chain uses solid rollers and robust, quad-riveted pins to achieve high durability while coping with frequent acceleration, braking and impacts from offroad non-sealed layout eliminates O-rings or X-rings, significantly lowering internal drag so that engine power reaches the rear wheel with minimal loss.
By combining low friction with a strong, precisely manufactured roller and pin assembly, the chain helps maintain stable chain tension, smooth drive operation and predictable throttle response during racing or intensive training sessions.
Typical Use Cases
The Tsubaki 428 MXC 128-link chain is intended for offroad motorcycles equipped with 428-pitch sprockets and a 128-link chain length is particularly suited to:
- Motocross bikes used in practice and competition on natural or artificial tracks.
- Enduro motorcycles ridden on technical singletrack, special tests and hard enduro stages.
- Trial and light offroad machines where precise clutch control and instant power delivery are important.
- General offroad use where a strong, low-friction non-sealed chain is preferred over sealed chains.
Installation Notes (General)
The 128-link length allows adaptation to various 428 sprocket combinations by adjusting wheel position and, where necessary, removing links with appropriate chain alignment, tensioning and lubrication are essential to maximize service life and maintain the performance benefits of the MXC series construction.
