I should say my cart is modified. Has Yamaha atv front suspension, so it has disc brakes. Motor is a Polaris 500 HO. Does 55 mph respectfully. A blast on the trails. I plan on tearing it down, full clean and paint after a few add-ons and some engineering changes to a couple areas. The cart we picked up last night has blown motor, so I will ponder that for a while before anything happens with it.
