Butterfly Quad 2014 Black (Chinese) I don't know about its engines, I last knew it was working last winter. Comes with two keys. Needs an oil change and battery, costs less than 70 SAR. I used it only 4 times last winter and then stopped using it. Note: (The plastic body of the quad is broken, but it doesn't affect the appearance of the quad). Price is negotiable. Bidding via private message with phone number. Sold as is. Sold as is. Sold as is.
