The MX142SP set contains two POM bushings intended for the fork tubes on 1/4-scale PROMO-MX motorcycles. Supplied as the front wheel pair, they replace worn factory bushings that cause excess steering play and inconsistent fork action.
POM material gives improved wear characteristics and a smooth bearing interface for the fork tubes, helping to reduce lateral movement and maintain consistent fork travel on track or trail.
Installation is direct: remove the fork assembly, replace the old bushings with the supplied POM units making sure they seat correctly, then reassemble and test for smooth, minimal free play. These parts are designed for service replacement rather than performance tuning.
