Uprated Ignition Coil Set :: Hyosung GV125 GT125 GV250 GT125R GT250 Carby ⚡️
🏁 Give your bike a noticeable spark boost! This upgraded ignition coil set is designed to improve spark strength and consistency across the entire rev range. You’ll likely notice smoother cold starts and more responsive throttle feel as you accelerate through the gears. Reliable ignition means your engine runs more efficiently and confidently.
📦 What this upgrade does: It provides a stronger and steadier spark compared to the standard coils, which can fade over time due to heat and wear. This is especially useful for carbureted Hyosung models that might struggle with weaker ignition output as they age.
| ⚡ Ignition Coil Set Includes: 2x coils (front & rear) |
🔧 Easy Fit: Direct replacement for the stock coils |
| 🧰 Installation: Simply remove your old coils and swap them for these upgraded units. (Need help?) |
🏍 Compatible Models: Hyosung GV125, GT125, GV250, GT125R, GT250 (Carburettor versions only) |
⛔ Not compatible with EFI models

These upgraded ignition coils are ideal for carbureted Hyosung motorcycles that need more consistent sparking power throughout the rev range. Standard coils can weaken over time due to heat and age, leading to sluggish cold starts and less responsive throttle action. By installing these coils, you can expect your bike to start quicker in colder conditions and feel smoother when accelerating.
For best results, consider pairing this ignition coil upgrade with NGK spark plug caps and NGK Laser Iridium spark plugs (available in our shop). This combination ensures you get the most reliable ignition performance possible.

Life changing part of you are looking to change coils. I’ve put my new coils through a lot during the problematic idle and power problems. Works so well with the regulator you can purchase here. A total must have.

Just changed these on a GV125 and it starts and idles so much better. They make life much easier on cold mornings
eman ellul –
Just upgraded to these coils, the uprated regulator, the uprated stator and ngk caps with iridium spark plugs. I have to say it made an amazing difference, the bike almost no longer needs choke (less than a minute and only on first start in the morning), acceleration has improved significantly and my bike is now charging (which was my original problem :p). Very happy with all items 🙂

Ordered these from Norway. Fast delivery and fantastic support from the team. Bike start much easier and feels snappier in the throttle response. Fitted this together with NGK Caps and Iridium spark plugs.
