I bought this quad. It didn't need a motor. Just changed the plugs. Suzuki never did make a 750 but a virtually unknown company, SAZUKI, did. This quad is the fastest and smoothest quad I've ever rode. Jumped over my house without even using a ramp and felt like I landed on a pillow. What's even cooler is the way the controls are setup my dogs can drive it. It gives a new meaning to dune dog.
