Genuine OEM CDI unit with a 5 pin plug, will not only help starting but will also produce smooth power delivery, with a good racing ignition advance curve.

Do not confuse this item with similar cheap Chinese copies that last only a short while until final failure.

It will work with kick or electric start engines and has an AC input so will work without a battery as well as with one.

Easy to install with no instruction required (plug & play)

Please check images against your current part for compatibility, typically used for bikesbetween 50cc and 140cc.

We also sell the high performance easy-start version if you wish to upgrade.
