Here's a brand new, aftermarket 43T/18T starter reduction gear.
This fits the 1987 Honda ATC250ES Big Red three-wheeler and replaces the Honda OEM part #28140-HA0-770.
This aftermarket starter reduction gear is made to meet or exceed Honda OEM specs!
*PLEASE NOTE: Often the cause of broken/damaged starter gears is a faulty one-way bearing. Inspect and replace the bearing, if necessary.
