This sled has a 4-stroke turbo motor. The track is in good shape with 96 studs. The sled also has heated grips and a thumb-warmer. The electric start and mechanical reverse both work well. The motor comes equipped with the 120V block heater for the cold days when it is hard to start. There is also wiring for a heated shield. We installed battery tender leads for easy battery charger hook-up. There is a spare key included with the sled, but there is no Owner's Manual or tool kit.
