Durable medium carbon sprocket set

The MX3511S sprocket kit is a scale replacement for the LOSI Promoto-MX 1/4 motorcycle RTR line. Both the rear hub sprocket and front sprocket use medium carbon steel to resist wear better than common stamped alternatives while keeping a direct fit to original components.

Made for plug-and-play swapping, the set focuses on long-term durability and consistent drivetrain behaviour without changing the installed gearing. The supplied screw pin mirrors the factory mounting approach to make fitment straightforward on compatible RTRs.

Installation notes: remove the stock hub sprocket and front pinion, retain any spacers or washers as required, install the 35T rear and 11T front sprockets, and tighten the screw pin to the manufacturer's torque guidance. Check chain alignment and run-in at low speed before normal running.

Packing includes

  • Hub Chain Sprocket 35T - 1pcs
  • Front Chain Sprocket 11T - 1pcs
  • Screw Pin M4x2.5x14 - 1pcs

Original Name / Part No:

LOS262003+LOS262004

Compatible Models

  • LOSI-1/4 PROMOTO-MX MOTORCYCLE RTR, FXR-LOS06000
  • LOSI-1/4 PROMOTO-MX MOTORCYCLE RTR, FXR-LOS06002

Use this set to replace worn sprockets or if you want less frequent part changes during practice; always recheck chain engagement and bearing condition after fitting.

Do these sprockets fit my Promoto-MX straight away?

They are intended as a direct fit to the listed Promoto-MX models and use the same mounting style for an easy swap.

Is the material stronger than stock?

Yes, medium carbon steel gives higher wear resistance compared with typical stamped sprockets, improving longevity under normal riding conditions.

Will I need to change chain length?

No changes to chain length are expected since this kit keeps the same 35T and 11T tooth counts; just check alignment after installation.

Any pre-fit checks recommended?

Confirm spacers and washers are transferred correctly, tighten to recommended torque, and run at low speed to confirm smooth operation.

How do I spot sprocket wear?

Look for hooked or uneven teeth and increased chain play; those signs indicate it is time to replace the sprockets.
