I was given this atv for my son from my friend. She isn't sure what kind it is. Its a 90cc 2 stroke. Any help greatly appreciated!

 

Very shiny plastic, I would guess at an Apache, as they have painted, hard plastics. They are regarded as about the best circa 100cc machines you can get. That engine is much better than the gutless 90 used by Suzuki now, and the quality and parts availability is better than the Chinese Kids Quads. It is Taiwanese.
