Promoto-MX 70 roller maintenance part

This chain roller is a service spare for the LOSI Promoto-MX motorcycle platform, combining a manganese steel chain element with a size 70 roller to re-establish lateral guidance and correct tracking on 1/4 scale units. The component is geared toward dependable drivetrain behaviour during practice runs or local events.

Fitment is aimed at the Promoto-MX RTR models listed below; fitting the replacement requires removal of the original roller, lining up the chain path and refitting to the factory mount. After installation, inspect chain tension and side-to-side alignment, and check the roller bracket for damage before returning the bike to service.

Primarily a routine maintenance item, this roller helps prevent uneven wear on the chain and sprockets and supports a consistent drive feel with fewer surprises under throttle.

Can I reuse the old mounting hardware?

If the original fasteners and mounts show no obvious wear or deformation they can be reused, but replace any suspect hardware and ensure proper torque on final assembly.

How do I check roller alignment?

With the chain fitted and lightly tensioned, spin the wheel and observe the chain path over the roller. There should be no side-to-side hunting and the roller should rotate freely without wobble.

Does roller size affect gearing?

This roller is a like-for-like replacement sized for chain guidance rather than changing effective gear ratio, so it should not alter gearing when installed correctly.
