Promoto-MX Front & Rear Wheel Buckles Upgrade MX0606FR by GPM  [MX0606FR]

Front and rear wheel pattern buckles for Promoto-MX

The MX0606FR kit swaps out the standard plastic hubs on 1/4-scale Losi Promoto-MX motorcycles for machined Aluminum 7075 buckles that improve component longevity at model scale. These pattern buckles clamp to the rim layout to reduce spoke distortion during hard landings and rough terrain.

The set is supplied as front and rear pieces and includes the fasteners listed below so installation does not usually require extra hardware. When fitting, ensure the buckle aligns with the rim pattern and bring the screws up evenly to avoid distorting the wheel.

Fitted buckles act as a simple tuning upgrade by limiting spoke flex and helping wheels stay truer after aggressive sessions, which supports more consistent tyre seating and handling on track or trail.

If you want to reduce wheel deformation and keep spokes aligned run-to-run, the MX0606FR Aluminum buckle set is a practical upgrade that fits the listed Promoto-MX kits and lowers routine wheel upkeep.
