My buddy works at an ATV shop. He had recently bought a race car, and needed money. so he sold me his quad. This thing is a beast. I grew up on 2 stroke dirt bikes, some quads. This thing is a torque monster. My buddy done alot of work to it. I wanna get new plastics eventually. This is the first Yamaha Ive owned.
