This aluminum chain tension adjuster is an RC-scale replacement crafted for Team Losi Promoto-MX motorcycles and identified as JR-LMX08-GR. It provides a stable, corrosion-resistant stop for final chain tension and lateral alignment tweaks on Promoto-MX style dirt bike kits.
Produced in aluminum with a green anodized surface, the unit replaces the original plastic or alloy adjuster while using the Promoto-MX factory mounting points on the rear end. The firmer construction preserves geometry during micro-adjustments, helping to keep chain slack consistent under typical 1/10 scale riding stresses.
Hobbyists familiar with motorcycle hop-ups will find installation direct: remove the old adjuster, position the JR-LMX08-GR at the factory fasteners, and tighten to the chassis specified torque. Verify chain tension through full wheel travel before running to ensure tracking is correct.
In tuning terms, the adjuster functions as a repeatable endpoint for small chain length and tracking changes. This helps when refining rear wheel tracking or when swapping chain types, with the aluminum body reducing setup variance between sessions.
