5-Pin AC Racing CDI Module for 50cc - 125cc ATV & Dirt Bike

GOOFIT High-Performance 5-Pin AC Racing CDI – Unlimited Power Series

Remove the restrictions and let your engine breathe. The GOOFIT 5-Pin AC Racing CDI is a high-output ignition module engineered specifically for the Chinese 4-stroke horizontal engine platform. Designed as a "No-Limit" upgrade, this CDI eliminates the factory-set RPM ceiling that prevents your bike from reaching its true top speed.

By resetting the ignition advance curve, this racing unit provides a more aggressive spark timing, resulting in sharper throttle response and significantly faster acceleration. Whether you are hitting the trails or the track, this module is the easiest way to gain immediate performance without mechanical modifications.

Why Choose the GOOFIT 5-Pin Racing CDI?

• Eliminate Rev-Limits: Factory CDIs often "govern" your speed by cutting the spark at high RPMs. The GOOFIT Racing CDI allows your engine to rev freely to its physical maximum, unlocking higher top-end velocity.
• Aggressive Acceleration: The remapped ignition advance curve fires the spark earlier in the compression stroke, providing a more powerful "kick" during take-off and through the mid-range.
• Stable Energy Discharge: Engineered for the high-vibration environment of off-road racing, this module ensures a consistent, high-intensity spark even at the limit of your engine's performance.
• Hassle-Free Install: No wire cutting or splicing required. Simply unplug your restrictive stock CDI and snap in the GOOFIT Racing module for an instant performance boost.
