Arctic cat tunnel with a 6.5hp 4 stroke motor. the motor has a tuned carb,exhaust with muffler and a ported head. I'm guessing it makes around 8Hp now. the headlight is powered by the motor so there's no battery's to worry about. I used it to get to haul gear to my property during the winter, ice fish and just cruising around the hills. it has pulled 4 guys and all our icefishing/camping gear for 2 days so it does pretty good. it does not come with the sleds to stand in I will be keeping those. let me know if you have any questions thanks!
