Aftermarket chain tensioner for Promoto-MX

This aluminum chain tension adjuster is an RC-scale replacement intended for Team Losi Promoto-MX motorcycles and listed as model JR-LMX08-GR. It offers a corrosion-resistant mounting point for final chain tensioning and lateral alignment adjustments on Promoto-MX style kits.

Machined from aluminum and treated with a green anodized finish, the adjuster replaces stock plastic or alloy pieces while retaining the Promoto-MX rear mounting locations. The stiffer material helps maintain factory geometry and reduces deformation during repeated settings common to 1/10 scale motorcycle use.

Installation follows the original mounting layout: remove the existing rear adjuster, align the JR-LMX08-GR with the factory fasteners and secure to the chassis recommended torque. Check chain tension through the full travel range to confirm correct alignment before operating the model.

Functionally, the part serves as a reliable endpoint for small chain length and alignment adjustments, aiding in rear wheel tracking refinement and reducing setup variance when changing chain types or performing maintenance.

How should I prepare the chassis before fitting the adjuster?

Ensure the rear mounting area is clean and free of debris, remove the original adjuster, and inspect fastener threads. Align the JR-LMX08-GR to the factory points before tightening to prevent misalignment.

Will this part keep settings stable during repeated runs?

The aluminum construction and anodized surface help resist deformation and wear, which makes chain tension settings more repeatable across multiple runs and maintenance cycles.
