I'd have to say back in the day at Honda Hills, um..let's call it 1986-1987ish on my buddies dad's 350x trike...Came off the top of the old ski jump when the teack ran opposite of the way it last ran and I thought I almost jumped to the bottom. Foot came off the peg, the knobbies tickled my heel, and I shot the corner. Rode back to the pits thinking I'd done something nobody else could have possibly done and still talk about it....
Been many 'o times I have reset that standard, but you said first....
