For me to get it to slide well, I've found that I have to brake WAY later than I think is possible and keep hanging on to the front brake. When I've been out at IMI trying to figure it out, at the end of the back straight I have to brake after Bjorn's slide marks start, then my bike slides well. Otherwise it just steps out a bit then snaps back in line.

So, just go so fast that there's no way you can make the corner. For me being a slow guy at least. If you were already fast, that might not work so well...
