JOYOR S8-Z Old Model Stem Bushing

The JOYOR S8-Z Old Model Stem Bushing is a precision-molded rubber or polyurethane bushing designed specifically for the steering stem assembly of the original (pre-redesign) JOYOR S8-Z electric scooter. It sits between the stem and headset to dampen vibration, reduce play, and ensure smooth, stable steering response. This part is installed at the top of the fork steerer tube, inside the headset cup, and works in conjunction with the stem clamp and top cap to maintain proper preload and alignment.

Replace this bushing if you notice excessive handlebar wobble, creaking noises during turns, or uneven steering resistance — signs that the original bushing has compressed, cracked, or lost elasticity over time. It’s also recommended to replace it during routine headset maintenance or after any front-end impact that may have compromised its integrity.

This is a genuine JOYOR replacement part engineered for direct fit on the legacy S8-Z model — no modifications required and fully compatible with the original stem and headset geometry.
