CDI Box 5 Pin Plug for XR CRF 50 70 90 110 125cc Quad ATV Taotao Kazuma Chinese Sunl

This 5 pin CDI box replaces the ignition control unit on 50cc to 125cc four-stroke machines, delivering the spark timing signal needed to start and run the engine, and cross-references common 5 pin CDI units found on XR, CRF, Taotao, Kazuma, and Sunl models.

Overview

This CDI box is a 5 pin ignition control module built for 50cc, 70cc, 90cc, 110cc, and 125cc four-stroke engines used in quads, ATVs, and dirt bikes. It manages spark timing so the engine starts reliably and holds a steady idle through the rev range. It suits riders and mechanics replacing a failed or intermittent CDI on XR, CRF, Taotao, Kazuma, or Sunl machines.

Built For Performance

• 5 pin plug layout matches the stock connector on most 50cc to 125cc four-stroke engines
• Solid-state ignition control for consistent spark timing across the RPM range
• Sealed housing resists moisture, dust, and vibration on off-road machines
• Direct replacement footprint for common Chinese ATV and dirt bike CDI units
• Compatible with CDI-style ignition systems on XR, CRF, Taotao, Kazuma, and Sunl models

Fits These Machines

• for Honda XR and CRF 50cc to 125cc models with 5 pin CDI
• for Taotao 50cc to 125cc ATV and quad models with 5 pin CDI
• for Kazuma 50cc to 125cc ATV and quad models with 5 pin CDI
• for Sunl 50cc to 125cc ATV and quad models with 5 pin CDI
• for generic Chinese 50cc, 70cc, 90cc, 110cc, and 125cc four-stroke quads and dirt bikes with 5 pin CDI

On-The-Job Use

• Replacing a failed CDI that causes no-start or intermittent spark
• Restoring reliable ignition on trail quads and youth dirt bikes
• Servicing 50cc to 125cc four-stroke ATVs used for recreation and light utility work
• Keeping spare ignition modules on hand for multi-bike workshops

Specs At A Glance

Good To Know

Q: How do I know this CDI fits my machine? A: Count the pins on your existing CDI connector and confirm it has 5 pins in the same layout. Also check the engine size falls between 50cc and 125cc four-stroke.

Q: Will a new CDI fix a no-spark condition? A: A failed CDI is one common cause of no-spark on these engines, but stator, pickup coil, and wiring faults can produce the same symptom. Test the ignition circuit before replacing parts.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
