Aluminum tensioner built for Promoto-MX durability

This RC chain tensioner is intended for Team Losi Promoto-MX motorcycle models and carries the model code JR-LMX08-BK. The anodized aluminum pieces offer a firmer pivot and mounting face compared with OE plastic adjusters, helping to resist flex and maintain alignment in rough conditions.

Fitting is direct on compatible Promoto-MX chassis using the original mounting points. During installation, verify axle alignment and tighten fasteners to the manufacturer's recommended torque, then check chain slack and lateral play before riding. This item is an RC replacement part and is not suitable for full-size machines.

For setup refinement, use the adjuster to set target chain sag and check alignment when compressing the suspension after any change to ride height or damping. Periodic inspection after hard off-road sessions will help reduce wear on sprockets and the chain.

How does the aluminum part hold up to repeated impacts?

The machined aluminum offers improved stiffness over plastic and resists deformation from typical trail and track impacts, though major crashes can still damage any adjuster.

Is there a coating to prevent corrosion in wet conditions?

Many aluminum adjusters are anodized to resist corrosion; confirm finish characteristics for JR-LMX08-BK and rinse the part after salt exposure to prolong life.

Will this reduce wear on sprockets and chain?

By maintaining more consistent alignment under load, the adjuster can help limit uneven wear, but routine lubrication and correct tension remain essential.
