This GPM MX142SP set supplies two plastic bushings intended for the fork tubes of 1/4-scale PROMO-MX motorcycles. The pair is designed for front wheel position use and is supplied as replacement bushings to restore correct fit where worn or loose factory parts affect steering alignment.
The parts are upgraded to POM material for improved wear resistance compared with generic plastics. In practice these bushings act as low-friction seating for the fork tubes, helping to reduce lateral play and maintain consistent fork movement during track or trail running.
Installation is straightforward: remove the fork assembly, replace the old bushings with the supplied POM bushings ensuring orientation and seating, then reassemble and check for smooth, minimal free play. They are intended as like-for-like service parts rather than performance upgrades.
