LOSI Promoto-MX Upgrade Chain Adjuster Gold Aluminum JR-LMX08-GD by Jazrider  [JR-LMX08-GD]

Promoto-MX chain adjuster features

The gold-finished aluminum chain tension adjuster set is an aftermarket option for the Team Losi Promoto-MX Motorcycle RC model. These components are intended to assist with precision tension adjustment and side alignment for RC motocross setups.

Adjust the unit in small steps to dial in chain tension and to remove lateral play between chain and sprocket. Correct alignment reduces the chance of premature chain or spur damage, and the machined aluminum provides a more rigid mounting surface than common plastic adjusters.

Fitting details: the adjuster set is compatible with the Promoto-MX adjuster mounting arrangement and replaces the stock adjuster hardware without modifying drivetrain geometry when installed properly. Always verify tension and alignment with a short test before full operation.
