For the GV125, GV250, and specific GT125 Naked models, fixing these leaks is essential maintenance for life on the road. This kit provides a reliable, direct replacement to restore proper front suspension function.

🔧 Install Tips

Inspect Tubes: Thoroughly clean your fork tubes. If you find rust pitting or deep scratches, these seals will fail quickly until the tube is replaced/repaired.
Use a Driver: Use a proper fork seal driver tool (or a carefully cut PVC pipe) to press the new seals evenly into place.
Manual Required: No instructions are included; please follow your service manual’s guide for correct disassembly and reassembly steps.
