LOSI Promoto-MX Motorcycle Aluminum Chain Tension Adjuster set by JAZRIDER JR-LMX08-GD  [JR-LMX08-GD]

Chain tension adjuster for Promoto-MX

This aluminum chain tension adjuster set is designed as an RC-scale replacement part for the Team Losi Promoto-MX Motorcycle model. The components provide a gold-colored aluminum option for fine control of chain tension and lateral alignment, intended for tuning and routine maintenance on RC dirt bike models.

Use the adjuster to make small, incremental changes to chain tension and to correct lateral play between the sprocket and chain. Proper alignment helps reduce premature wear on the chain and spur gear in RC setups, and the machined aluminum parts offer a stiffer mounting point compared with many stock plastic adjusters.

Installation notes: the set fits the adjuster mounting interfaces on the Promoto-MX chassis and replaces the existing adjuster hardware without altering drivetrain geometry when adjusted correctly. After making adjustments, verify tension and alignment with a short test run before full operation to confirm the setup.
