That corner is called the Snake At Mulholland, it's a 25mph turn uphill and a steep bank to the left but flatten out at the top. You really have to drag your knee or extreme lean angle otherwise you will go wide every time if you don't do the speed limit. When you first take that turn you would think with the steep bank you wouldnt have to lean as much but you do. Thats the mistake people make. Just about every time I go there somebody lays their bike down. Most people try to take it at 45mph and that is really pushing it and it's definitely not for the novice. It's has gotten too crazy with cars trying to drift around that corner and end up crossing the yellow line.
That girl in the video is there every Sat and Sun with MickeyMouse taking photos of you leaning and sells the photo if you want to buy it. All the celebs hang out there and it's just down the road from the famous rock store.
