oh that, They were filming it for a Extreme video I think.
I dont think it is really trailrideable.. sorta like running a rail on a gravel road.. just not made for it, bet its very hard on nitr as well
Because it is running on nitro, it said they had to pack a generator ,blankets etc to get everything warm enough to run where they were filming. They had to find a long enough hill to allow for its speed, he has come off it at 120 mph. At his shop he had a pic on his computer of one of his other sleds about 30 ft in the air at the top of a hillclimb.. one that most machines donot get up or barely make it.. His 2 stroke wouuld do 8 sec 1/3s on pavement..
