Description
Hyosung silently changed the flywheel size on their facelift 125cc carb models, making the smaller OEM replacements difficult and expensive to source. This HyoRiders conversion kit solves that problem while offering a genuine performance upgrade. We combine robust, upcycled hardware with a brand new uprated stator to give your bike a punchier idle, stable electrics, and the reliability you need for touring.
💎 Performance with the reliability!
A bigger flywheel isn’t just about reliability; it delivers a better feel where you need it most—punchier acceleration and stable electrics at high RPMs.
| Better Torque Pulls harder from low RPM. |
Stable Electrics Consistent power delivery. |
| Fast Starts Shoots up to 1500 rpm cold & quick. |
Cooler Running Thicker stator reduces heat buildup. |

This custom kit is brilliant and well worth the money. My old stator was fried by faulty electrics which had to be replaced.
This stator is much better and the new flywheel gives a big boost in torque. Throttle is much smoother and responsive. Handles lower speeds in a higher gear perfectly where as the old stock one felt really flat. 30mph in 4rh gear no problem.
The bike just loves this.
Again decent service and quick delivery. All parts and tools needed are supplied along with excellent step by step instructions by Marcel. I never attempted anything like this before and with the step by step guidance fitted it perfectly.
If you’re ordering a new stator definitely consider this full kit.
