X-PRO^® Starter Relay for 4 Stroke 50cc-250cc ATV Dirt Bike Scooter Go Kart
[270-999001]

Used this solenoid to replace a failed solenoid on my kids 110cc Coolster 4-wheeler. All the connections where the same and it worked as expected. It does come with the rubber boot to protect the battery terminal and starter terminal connectors.
