Description

Here is a part that is sometimes hard to find; the 9 tooth starter motor for 125cc/150cc, 250cc, & 400cc ATVs & dirt bikes. It features clockwise rotation.

This 12 volt starter motor is compatible with the Baja Wilderness Trail 400 (WD400-U).

The starter motor does not include the mounting bolts, so you will need to reuse your scooter or ATV's original bolts.
