I'd probably just rent a dirt bike for a day and slide that around, wouldn't want anything to happen to a new scr950 and that kind of riding requires more control than I have. Did you see him fishtail a bit when he pulled it upright again?
Or just hope that Yamaha plans to have some test day for regular folks and not just the media. It's the only way i would do this sort of thing, aside from that i'm mainly a street guy. The most off road I get is with the grass and pebbles surrounding my cottage
