Promoto-MX precision chain roller

This replacement chain roller is an RC-scale drivetrain spare engineered for the LOSI Promoto-MX motorcycle platform. It combines a manganese steel chain element with a size 70 roller to restore accurate lateral guidance and consistent tracking on 1/4 scale Promoto-MX motorcycles. The component is produced to support dependable drivetrain operation during sustained running.

Fitment targets the Promoto-MX RTR models listed below; installation requires removal of the existing roller, correct alignment of the chain path and secure attachment to the original mounting points. After fitting, inspect chain tension and lateral alignment, confirm the roller has no play and check the mounting interface for wear or deformation prior to reuse.

As a service-focused upgrade item, the roller is intended to reduce uneven wear on chain and sprockets and to stabilise drive feel under throttle transitions, with material choice optimised for contact point durability.

Does the MX070 require any frame modification?

No frame modification is expected when fitting the MX070 to compatible Promoto-MX RTR units; the part is manufactured for direct integration with existing mounting points provided those points are in serviceable condition.

What inspection steps ensure correct installation?

Confirm the roller is seated square to the chain path, verify axial clearance is within acceptable limits, ensure free rotation under light load and torque fasteners to recommended values for a secure fit.

Why specify manganese steel for the roller contact?

Manganese steel is selected for its enhanced wear resistance at chain contact surfaces, maintaining roller geometry and guidance performance under repetitive RC drivetrain loads.
