When entering and negotiating a sharp bend or curve on a two-wheeled motorcycle, what is the safest control technique?

1. Accelerate aggressively into the curve and brake hard at the apex
2. Coast through the curve in neutral with the clutch lever pulled in
3. Look down at the front wheel and apply the front brake throughout the lean
4. Complete deceleration and gear selection before entering the curve, look through the curve toward the exit, and maintain smooth, gentle throttle (慢进快出/进弯前减速)
