Wear-resistant medium carbon sprockets

The MX3511S sprocket kit is designed as an RC-scale replacement for the LOSI Promoto-MX 1/4 motorcycle RTR. Both the rear hub sprocket and front pinion are manufactured from medium carbon steel to give improved wear life over standard stamped items while retaining a straightforward fit to factory parts.

As a direct replacement, the kit emphasises consistent drivetrain performance and part longevity rather than altering gear ratios. The included screw pin matches the factory mounting approach for a simple swap on supported Promoto-MX RTR units.

Installation notes: remove the original hub and front sprockets, move across any spacers or washers as required, install the 35T rear and 11T front sprockets, and secure the screw pin to the recommended torque. Check chain alignment and perform a short break-in before full-power use.

Packing includes

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

Choose this set for longer service intervals and a more durable drivetrain under practice use; always verify chain tension and alignment after fitting to protect wear items.

Will these sprockets fit my existing chain?

Yes, the tooth counts match the original parts so your existing chain should work without length changes, though alignment should be checked.

Are these parts more durable than stock?

Medium carbon steel is chosen for improved wear resistance over standard stamped sprockets, giving longer service life in typical riding conditions.

Do they affect handling or power delivery?

No handling change is expected since gear ratios remain the same; the goal is steadier drivetrain behaviour and reduced wear.

Can I reuse the original spacers?

Yes, transfer any original spacers or washers as required to preserve correct chain alignment and bearing preload.

Recommended break-in procedure?

Run the bike at moderate speed for a few minutes while monitoring noise and alignment, then recheck chain tension before normal operation.
