Rieju Chain Slider Kit for MR Series (2021-2026) & GasGas EC/XC (2018-2020)

Product Information

This OEM Rieju chain slider kit is designed to protect the swingarm from chain contact and premature wear while maintaining proper chain alignment.

Mounted directly to the swingarm, the chain slider reduces friction between the drive chain and aluminum surface during acceleration, deceleration, and suspension compression. Over time, sliders wear down from constant contact. Replacing them before excessive wear helps prevent costly swingarm damage.

This kit is engineered for direct fitment on 2021–2026 Rieju MR models and 2018–2020 legacy GasGas EC and XC platforms that share the same chassis architecture. Installation is straightforward using factory mounting points, making it a practical maintenance item for trail riders, racers, and high-hour bikes.

Whether you're refreshing your drivetrain during a chain and sprocket service or replacing a heavily worn slider, this OEM kit helps maintain drivetrain longevity and proper chain tracking under real-world riding conditions.
