Collection: CDI

The CDI (Capacitor Discharge Ignition) unit controls the timing and firing of your spark plugs. When it fails, the engine may misfire, run rough, refuse to start or cut out unexpectedly.

4Drive stocks CDI units and ignition components for:

  • Motorcycles — Honda, Yamaha, Kawasaki, Suzuki, KTM, Aprilia and many more
  • Scooters & mopeds — 50cc, 125cc and larger models
  • ATVs & dirt bikes — off-road and powersports applications

CDI units are often model-specific. Use your OEM part number for a guaranteed fit, or select by make, model and year. Free UK delivery on orders over £150.
