Promoto-MX Motorcycle Chain Tension Kit — Aluminum Precision JR-LMX08-DB by JAZRIDER  [JR-LMX08-DB]

Precision axle adjusters for Promoto-MX swingarms

This chain tension adjuster set is produced for the Team Losi Promoto-MX Motorcycle platform by JAZRIDER and machined from aluminum with a blue finish. It replaces the factory plastic adjusters to give a more stable adjustment point for chain tension and axle alignment on RC dirt bike chassis.

The kit is built to let you dial in chain slack and to maintain driveline alignment after suspension or drivetrain changes. It mounts at the swingarm axle position and is compatible with the existing axle hardware, providing controlled movement so you can match chain tension on both sides accurately.

Installation tips: locate the adjusters at the axle slot, ensure the axle seats evenly in the adjuster, and use incremental adjustments to reach the desired chain tension before securing the axle. After final tightening, confirm the chain runs true and the rear wheel spins freely. Intended for RC dirt bike maintenance and users experienced in chassis tuning.
