This one has a 740 cubic inch Arias blowr motor,about 3,000 horsepower at full throttle.Which is in your right hand,steer with brake pedals when its riding high.Thanks Mike,it was a rough rider as the video shows,the last bounce at the end got my attention pretty good,neck is still sore.But it was fun. If you think the video is loud,you should be sitting behind that brute,even with ear plugs and a helmet you cant hear your self scream.
