This lean bar wheel set is designed for the LOSI Promoto-MX 1/4 scale motorcycle platform and comprises CNC-machined alloy components that hold shape on impact while allowing controlled flex for believable leaning behaviour.
Use scenarios: components are suited to applications where predictable movement and impact resistance are required, such as tuning sessions or durability upgrades on Promoto-MX RTR units. Fitment details: the wheels and included hardware replace the original lean bar assembly and act as a tuning part to influence lean behaviour and longevity without touching the electrics or drive train.
Fitting guidance: check the listed Promoto-MX RTR part numbers for compatibility, confirm bearing and shim orientation, and apply moderate fastener torque to avoid over-clamping which can prevent designed flex. Installation requires only common RC tools and standard chassis mounting points.
