GPM Racing Aluminium 7075 Front & Rear Wheel Pattern Buckle for Losi Promoto-MX Motorcycle RTR FXR (MX0606FR)

Front and rear wheel buckles for Promoto-MX applications

The MX0606FR set replaces the standard plastic wheel hubs on 1/4-scale Losi Promoto-MX models with machined Aluminium 7075 pattern buckles intended for improved durability at the model level. These buckles clamp to the rim pattern and limit spoke movement under repetitive impacts and load cycles encountered in off-road use.

The kit is supplied as a matched front and rear pair including the specified fasteners so installation is straightforward without extra hardware. Correct alignment to the rim pattern and incremental, balanced screw torque are key to avoiding wheel distortion during fitting.

In operation the buckles serve a tuning function by stabilising spoke geometry and helping wheels retain trueness after aggressive sessions, which improves tyre seating consistency and handling repeatability.

What rim pattern must be matched?

Match the rim pattern to the compatible model codes in the compatibility box. These buckles are engineered for that specific pattern and may not seat correctly on other designs.

What torque practice is recommended?

Tighten screws progressively and evenly, checking seating after each pass. Avoid single-point over-torque to prevent rim distortion.

Is re-torquing required after first run?

Yes. Inspect and hand-check screw torque after the first few runs, and re-torque incrementally if any loosening is observed to maintain secure seating. Write Product Review Please sign in your account before you can write any review. Sign In Close
