Right-Hand Curve With Sand and an Oncoming Truck
Miguel is leading two friends on a 600cc sportbike on a two-lane mountain road at 4:30 p.m. The right-hand curve ahead is posted 35 mph and tightens near the exit; the surface is dry except for a band of sand and gravel along the outside edge. Miguel enters at 45 mph in the center of the lane, and as he leans he sees an oncoming pickup drift about two feet over the centerline. His tires are still cool from a gas stop two minutes earlier, and his front brake lever has about an inch of free play. The rider behind him is following at a one-second gap and is looking at Miguel rather than through the curve. Miguel’s visor is clean, but the low sun is directly in his eyes.
1. Where should Miguel have positioned the bike for this right-hand curve, and how does the oncoming pickup change that plan?
Read the worked answer
The usual line for a right-hand curve is to enter from the left side of the lane, which widens the arc and improves the view through the curve. Here that plan conflicts with two hazards. The sand and gravel are on the outside edge, which is the left edge in a right-hander, so the left side is slippery. The pickup is also over the centerline, so the left side is a conflict zone. Miguel should slow before turn-in and use the center of the lane or the right tire track, staying off the sand and away from the centerline. He should not stare at the truck; his eyes should go to the exit. If the truck drifts farther over, he needs a plan to move right without leaning onto the gravel or grabbing the brake.
2. Miguel realizes mid-curve that 45 mph is too fast. What are his options, and what should he not do?
Read the worked answer
He should roll off the throttle smoothly, keep looking through the exit, and allow the bike to lean a little more if the tires are on clean pavement. If he must slow, he should use both brakes gently while reducing lean angle; hard braking while leaned over can overload the front tire. He should not chop the throttle, because engine braking can make the rear tire step out, and he should not stand the bike up and run wide toward the oncoming lane. Grabbing the front brake on the sand would likely cause a front-wheel slide. The free play in the lever also means the brake may engage later than expected, so he should not rely on a sudden hard squeeze. Smooth inputs and a wider exit are safer than a violent correction.
3. What should the following rider do differently?
Read the worked answer
The follower is too close at one second, especially in a curve with sand and an oncoming truck. A two-second gap is a minimum on a clean road; in a curve, with limited sight distance, it should be larger. The follower should look through the curve, not at Miguel’s back, so he can see the sand and the pickup for himself. He should not copy Miguel’s line blindly. In a staggered group, each rider needs his own escape path and his own view. If Miguel brakes or runs wide, a one-second gap leaves almost no time or space to react. The follower should drop back, widen the gap, and be ready to slow before the sand rather than mid-corner.
