Gravel in a Blind Right-Hander
On a damp October morning, Priya rides a 400 cc standard at 52 mph on a two-lane Indiana county road posted 40 mph. A blind right-hand curve is ahead. She sees gravel scattered across the outside half of her lane, a fresh deer-crossing sign, and a pickup about two seconds behind her. The pavement is wet but not raining. Her tires are warmed only by 5 miles of riding. She is in the right tire track, and the curve tightens near the exit. She must decide entry speed, lane position, and brake use. She has ABS. A deer could appear at any point, and the pickup is close enough that a sudden hard brake without warning worries her.
1. How should Priya set up for the curve: speed, lane position, and braking? Explain the trade-offs.

Priya should do her braking before the curve, while the bike is upright and the tires have maximum traction. At 52 mph into a damp 40-mph blind right-hander with gravel, she is carrying too much speed. She should progressively squeeze both brakes-ABS helps but does not create traction on gravel-and slow to roughly 30–35 mph before turn-in. She should flash the brake light early to warn the tailgating pickup, then release brake pressure smoothly as she leans. Lane position should avoid the gravel on the outside while giving the best sightline; that may mean center or a clean inside line, not the right tire track. She should not trail-brake hard across gravel or fixate on the pickup. If the pickup stays close, the safest response is still smooth, predictable speed reduction, not a sudden panic stop mid-corner.
2. What should she do if the rear tire steps out on the gravel mid-corner, or a deer appears at the exit?
Read the worked answer
If the rear steps out on gravel, she should stay light on the bars, keep a steady throttle or slight roll-off, and avoid grabbing the front brake; a sudden brake in a lean with poor traction can cause a low-side. She should look through the curve and let the bike stabilize. If a deer appears at the exit, she should straighten the bike as much as possible and brake hard in a straight line if there is room, rather than swerving into the oncoming lane. ABS helps prevent front-wheel lockup, but it cannot overcome gravel or wet pavement. After the hazard, she should pull over when safe, check tires and brakes, and adjust speed for the remaining damp county road.
