The MX0606FR replaces the standard plastic wheel hubs on 1/4-scale Losi Promoto-MX bikes with machined Aluminum 7075 buckles built for durability at the model level. These pattern buckles clamp to the rim geometry to reduce spoke movement under the knocks and jumps common in off-road running.
Delivered as a front and rear pair, the set includes the matching fasteners so you can complete the swap without sourcing extra screws. Careful alignment of the buckle to the rim pattern and gradual screw tightening are important to avoid wheel distortion during installation.
Once fitted, the buckles help keep the wheel true after heavy use, which supports more consistent tyre seating and predictable handling during practice or track days.

For riders aiming to cut down on wheel-related adjustments, the MX0606FR Aluminum buckle set provides a robust upgrade that fits the listed Promoto-MX kits and reduces the need for frequent spoke truing.
