    • Great seller, arrived quickly
Color: 150CC 4-Stroke, Electric/Kick Start
The motor arrived quickly by UPS and the motor was packaged in styrofoam so there was a decent amount of protection for it inside of the box. Came with the accessories as shown in the images. Great seller, quick shipper.
