Racing CDI 5-Pin DC for 50cc, 70cc, 90cc, 110cc, 125cc ATV & Scooter

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

Take the leash off your small engine. The GOOFIT 5-Pin DC Racing CDI is a premium "No-Limit" ignition module engineered specifically for DC-powered 50cc to 125cc machines. While standard CDIs are designed to restrict your engine for safety, this racing module is built to unlock your vehicle's full RPM potential.

By utilizing DC-fired technology, this CDI draws steady 12V power directly from your battery rather than the stator. This results in a consistent, high-intensity spark that remains stable across the entire RPM range, ensuring your engine doesn't "break up" or stutter at high speeds.

Why Choose the GOOFIT 5-Pin DC Racing CDI?

• Eliminate Restrictive Rev-Limits: Factory ignition units often cut the spark before your engine reaches its peak power. Our racing CDI allows the engine to rev freely to its physical maximum, increasing your potential top-end speed.
• Enhanced Acceleration Curve: This module resets the ignition advance curve, firing the spark plug earlier during the compression stroke to provide sharper throttle response and harder mid-range pull.
• Battery-Powered Stability: Because it is DC-fired, the spark intensity does not depend on engine RPM. This ensures easy starting (even in cold weather) and a perfectly smooth idle.
• Rugged Racing Construction: Housed in a durable, vibration-proof shell, this CDI is designed to survive the rigors of off-road trail riding and track use.
