The U-Turn That Dropped the Bike
Priya has been riding her first motorcycle, a 300 cc single, for three weeks. In a 24-foot-wide practice lot, she tries a U-turn at about 8 mph. She keeps two fingers on the front brake, looks down at the painted line, and lets the clutch out fully halfway through the turn. The bike lurches, she grabs the front brake, the front wheel washes out slightly, and she stalls and drops the bike at walking speed. Later, at the lot exit, she must stop on a downhill slope covered with a light layer of gravel before entering a 35 mph road. She is shaken and wants to know why the bike fell and how to handle the downhill stop.
1. Diagnose why the bike fell during the U-turn.

The fall is a slow-speed control failure, not a mysterious loss of grip. Priya made four compounding errors. She kept fingers on the front brake during a tight turn, which makes it easy to apply a sudden front-brake input when the bike lurches. She looked down at the line instead of through the turn, so her steering and balance followed her eyes downward. She released the clutch fully at low speed, removing the friction-zone control that keeps power smooth. When the bike lurched, she grabbed the front brake, and at full lean the front tire had little reserve for braking. The fix is to use the friction zone continuously, keep the throttle steady, look through the turn to the exit, and use light rear brake rather than the front brake to control speed in a tight slow turn. At walking speed, smoothness matters more than any single control.
2. Describe the correct slow-speed U-turn technique for this lot.

Set up wide, shift into first, and slip the clutch in the friction zone before turning. Keep the throttle steady and use the rear brake lightly to regulate speed. Turn your head and eyes to the exit, not the painted line, and let the bike lean while you stay balanced. Do not grab the front brake; if speed needs correction, use the rear brake or a small clutch adjustment. Keep the turn within the available width and be ready to straighten the bike if you drift wide. If the bike starts to fall, the immediate priority is to stop smoothly rather than fight the lean with a sudden brake. Practice the same turn both directions at a consistent low speed before attempting the exit onto the road.
3. Explain how Priya should handle the downhill stop on gravel.
Read the worked answer
She should reduce speed before the slope and avoid carrying unnecessary speed onto loose gravel. On the downhill, use both brakes progressively, with the front brake doing a large share of the stopping because weight has shifted forward, but apply it gently rather than grabbing. The rear brake can help stabilize the bike, but it has less effective traction downhill and on gravel. Keep the handlebars straight, look at the intended path, and pull in the clutch as she nears a stop so the engine does not push her forward. If the front wheel begins to slide on gravel, she should ease off the front brake rather than clamp harder. She should also choose a spot with better traction if one exists, and she should not enter the 35 mph road until she is stopped, in first gear, and has checked traffic.
