How should a motorcycle rider position their body when riding through low-speed tight U-turns or slalom maneuvers?

1. Lean the body far to the inside of the turn while keeping the bike vertical
2. Counter-lean: keep the torso upright or slightly to the outside while leaning the motorcycle beneath you, maintaining balance with clutch friction zone and light rear brake
3. Drag both feet on the pavement at 30 km/h
4. Lock the front brake and turn the handlebar
