This anodised purple aluminium rear brake disc is made as a direct replacement part for the Team Losi Promoto-MX motorcycle scale model, offering a corrosion-resistant metal alternative to the standard plastic disc for improved durability.
Installation on the standard Promoto-MX rear hub is straightforward: remove the original disc, align the replacement on the hub face and secure using the existing fasteners. No specialist equipment is necessary beyond the model's normal hex driver; spacers and retainers fitted to the hub remain unchanged. Always confirm correct thread engagement and tighten to the manufacturer's recommended torque figures.
When tuning and maintaining the model, this aluminium disc helps provide a more reliable braking feel and reduces surface wear in comparison to softer materials. Enthusiasts frequently choose an anodised metal disc when they require repeatable braking performance or need to replace a worn component.
