Break through the factory-imposed speed limits of your Kymco or SYM scooter with the Naraku Performance Unlimited CDI. Most stock 4-stroke scooters are equipped with a restrictive ignition box that "cuts out" just as you reach your peak power band. This high-performance Naraku unit features a de-restricted ignition curve with no RPM ceiling, allowing your engine to rev freely to its true mechanical potential. Expect improved throttle response, smoother acceleration, and a significant increase in top-end speed.
Advanced Ignition Technology
- Unlimited RPM: Completely removes the factory governor, allowing for higher top speeds—especially when paired with performance variators and exhaust systems.
- DC-Fired Reliability: Designed specifically for DC (Direct Current) ignition systems, providing a consistent, high-energy spark regardless of engine RPM.
- Optimized Timing Curve: Features an advanced ignition map that provides better "snap" off the line and more stable power through the mid-range.
- Taiwanese Precision: Manufactured in Taiwan by Naraku, a world leader in small-engine performance electronics, ensuring maximum durability and vibration resistance.
