How should a motorcycle rider navigate a curve that has visible patches of windblown sand on the road surface?

1. Accelerate hard and lean as low as possible to cut through the sand
2. Slow down before the sand, reduce lean angle (keep bike more upright), steer smoothly, and avoid sudden braking or throttle changes
3. Lock the rear brake and slide through sideways
4. Close eyes and coast with hands off the handlebars
