Front Fork Race and Bearing Kit for CSC Go and GY6 50cc Scooters

This kit is made for CSC Go and 139QMB 50cc scooters and works as a full OEM replacement for the upper and lower fork bearings. It is one of the GY6 50cc scooter parts that supports smooth steering and stable handling.

Purpose and Replacement

The kit contains the upper and lower bearing cups needed for correct fork assembly. These parts play a key role in keeping the steering system working properly. If you notice steering problems or have taken the front fork apart for service, replacing these bearings is a good idea.

What Comes in the Box

You get a steering nut and the lower bearing assembly, so the kit covers a complete replacement. Bearing grease is not supplied, so you will need to buy it separately for proper lubrication.
