Team Losi Promoto-MX Rear Brake Disc Upgrade, Anodized Purple - JR-LMX07-PU by Jazrider  [JR-LMX07-PU]

Anodized purple rear rotor crafted for Promoto-MX

This anodized purple aluminium rear brake disc is manufactured as a direct replacement for the Team Losi Promoto-MX motorcycle scale model, giving a durable metal option that stands up better to wear and environmental exposure than the standard plastic disc.

Installation on standard Promoto-MX rear hubs is straightforward: remove the factory disc, align the replacement on the hub face, then secure it using the hub's original fasteners. Typical hobby hex drivers are sufficient and existing spacers or retainers remain in position. Always verify correct thread engagement and tighten to the chassis maker's specified torque.

For tuning and upkeep, the metal disc reduces rapid wear and provides a more consistent pedal response across repeated runs. Model builders often choose an anodized disc when they prioritise repeatable braking characteristics or replace a degraded original component.
