This MX142SP kit supplies two POM bushings made for the fork tubes on 1/4-scale PROMO-MX motorcycles. The two-piece set fits the front wheel positions and replaces worn or loose factory bushings to help restore correct steering alignment.
The POM construction offers superior wear resistance versus generic plastics and provides a low-friction seating surface for the fork tubes, which helps limit lateral play and keeps fork motion consistent during track or trail use.
Fitting is simple: remove the fork assembly, swap the old bushings for the supplied POM parts making sure they seat correctly, then reassemble and verify smooth operation with minimal free play. These are intended as service replacements rather than high-performance upgrades.
