JOYOR S10-S Steering Stem Tightening Wrench

The JOYOR S10-S Steering Stem Tightening Wrench is a precision tool designed specifically for adjusting and securing the steering stem on the JOYOR S10S electric scooter. It fits the headset assembly at the top of the fork, where proper torque application ensures stable, wobble-free steering and safe handling. This wrench enables accurate tightening of the stem cap bolt without over-torquing or damaging threads.

Use this tool when performing routine maintenance, after replacing the stem or headset components, or if you notice handlebar play or looseness in the front end. Its custom shape matches the unique hex profile of the S10S stem cap, providing full contact and preventing slippage during adjustment.

This is a genuine JOYOR service tool engineered for direct fit and optimal function on the S10S model — no adapters or modifications required.
