This aluminum front wheel hub hex is a direct-fit aftermarket part produced by GPM for LOSI PROMOTO-MX 1/4-scale motorcycles. Built from 7075-T6 aluminum, the design emphasises stronger fixation and increased bearing support to improve the guidance and rotation consistency of the front wheel hub in RC motorcycle setups. The package includes the hub hex, a bearing positioning column, and two 5x14x5 bearings to simplify replacement and maintenance.
Use this part when replacing a worn plastic hub or when upgrading to a more durable metal hub to reduce flex at the wheel mounting point. The added bearing capacity reduces play under load and can help maintain alignment in aggressive riding or during long run sessions on track or trail surfaces suitable for 1/4-scale PROMOTO-MX models.
