Product Information
The YCF Racing CDI Box for Select YCF Bikes (2024–2025) is a performance-focused ignition upgrade designed to give riders an edge. Unlike a standard CDI box, this racing version features faster-charging capacitors and improved circuitry, resulting in a stronger spark and higher maximum RPM.
This means quicker throttle response, more powerful acceleration, and the ability to push your bike further before hitting the rev limiter. Many racing CDIs also allow for more aggressive ignition timing, offering riders a custom-tuned feel straight out of the box.
Whether you’re chasing faster lap times or simply want your bike to feel more responsive, this racing CDI delivers noticeable improvements in engine performance while maintaining the durability expected for motocross and pit bike use.
