Aftermarket Ignition Coil – Carby Hyosung GV125 GT125 GV250 GT125R GT250
Solve starting and running issues instantly. This aftermarket coil set provides a stronger, more consistent spark compared to aged OEM units, ensuring snappier throttle response and easier cold starts for your V-Twin. Original factory makers in Korea are no longer manufacturing these components as they shifted focus over to modern fuel-injected setups, making a fresh Hyosung ignition coils kit the single best way to restore your spark system during a maintenance project.
- Snappier Throttle // Noticeable spark boost across the rev range for sharp power delivery during your daily riding.
- Easier Cold Starts // More reliable ignition when the weather turns chilly or when prepping the bike after winter storage.
- Stable Idling // Helps maintain a consistent running engine and removes erratic drops in your RPM needle levels.
- Box Contents // Arrives as a set of two (you get 2x coils), including both the front and rear cylinder coils required for a full ignition service.
❌They are NOT compatible with later EFi models which use two spades. Check your connector type before ordering.
Description
If your carbureted Hyosung is actively struggling along with sluggish cold starts, unstable idling patterns, or random misfire issues during daily riding, the high-voltage electrical coils are a prime suspect. The original factory equipment parts fade heavily over time due to continuous engine bay heat cycles and wiring age. Because original factory makers in Korea are no longer making these specific components as they moved on to fuel-injected machines, sourcing this quality aftermarket Hyosung ignition coils set is a crucial step. It is a direct, reliable replacement designed to restore and improve spark strength and consistency across your full rev range during a restoration project.
This aftermarket set provides a stronger and steadier spark compared to standard coils, which is especially vital for maintaining optimal performance for your V-twin layout. Many owners find that weak electrical fields look like fueling bugs when the real issue is simply tired core windings inside the frame rails. This package comes complete to handle both front and rear cylinders simultaneously on your workbench, giving you absolute peace of mind during long road trips or daily commuting journeys.

🔧 Installation Tips & Recommended Synergy Upgrades
Replacing your electrical coil units is completely straightforward, but maximum ignition performance relies heavily on the full secondary setup. Follow these pointers on the workbench:
- Easy Fitment: Simply unbolt your aged original factory hardware units from the mounting brackets under the panels and swap them for these upgraded components using original screws.
- System Synergy is Critical: The standard black spark plug caps are often made from cheap plastic compounds that gather green rot and break down under heat. They frequently look like a full coil failure, but the cap is the real culprit short-circuiting your lines!
- Upgrade Your Plug Terminal Caps: Move away from fragile factory plastic and fit a set of high-durability rubber covers to secure an absolute weather barrier: [View NGK Plug Caps].
- Maximize Combustion with Precision Plugs: Ensure your fresh electrical current burns your fuel charge completely. Combine these aftermarket coils along with premium dual-precious metal firing pins to optimize throttle crispness over long road trips: [View NGK Laser Iridium Plugs].

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.

Martin –
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.
